You can freely set the order in which the GT-8’s effects are connected as well as the send and return levels.

BOSS’s mega-popular GT-6 was a smash hit with guitarists, now the GT-8 is destined to become the go-to box for gigging and recording guitarists alike. This DVD is a must have for anyone who buys a GT-8. I have already learned to navigate, with confidence, my GT-8 and I am very pleased with my results. If you ask me Roland would better serve their customers by including a copy of your DVD with every unit. Invaluable toll well worth the price. M M.V.D.(. FAR MORE THAN A TUTORIAL FOR BOSS GT-8 PEDALBOARD David Wills has the ability to make learning far more easier than just reading word by word from a text manual that may have terms not in the vocabulary or pictographic knowledge for musicians in different professional stages. My personal experience with this video and others in areas (software) definitely makes proaudioexp an excellent option to recommend for any musician that is in search towards improving their skills and making the best out of their professional equipment. At a proper time rate and full understanding in the easiest way. Highly recommended. J J. Great product!

If you're new to the GT-8 and like it, this DVD will incredibly cut the learning curve!! An excellent product! A A.D. Excellent starter for the GT-8 I have 2 instructional DVDs for the GT-8, the other being the Lick Library Ultimate Gear Guide. I found I knew much more about the GT-8 (and effects, amps, and so on) after watching this DVD than the Lick Library DVD. This manual taught me about what the GT-8's functions mean as well as how to manipulate the unit to get what I want, and that extra understanding is really where this DVD scores over others. Highly recommended. K K.D.H. Boss GT-8 This is a very complex piece of equipment,( GT-8 ) I for one am not very tech savy. This video is helpful, along with the owners manual, I can get the effects desired. Even with the video's help, time is required to get all possible out of the Boss GT-8's potential. I do recommend the product for those who could use the extra help with their GT-8. M M.L.M.i.F.(.A.U. Highly reccomended I ve learned more within the first hour of watching this DVD; than I ever had in reading the instructional manual that I ve owned for months. If you are not technologically adept I recommend this buy. K K.D.H.K.D.H.(.N. Make complex GT-8 easy This is a very complex piece of equipment,( GT-8 ) I for one am not very tech savy. Even with the video s help, time is required to get all possible out of the Boss GT-8 s potential. I do recommend the product for those who could use the extra help with their GT-8. O O.M. Very clear and useful DVD manual The Boss GT-8 is rather easy to operate and the DVD just make it easier to learn all its main features. I warmely recommend it. Unfortunately, the pot is a little plastic thing and it's not bolted to the metal chassis. So, it's not difficult to break this thing if you use it quite often. In this case, the pot was cut in half and didn't work anymore. So I bought a metal mini-pot (dual 50kA) which could be mounted to the metal chassis of the gt-8.
http://dieter-sauter.com/images/boss-gt-8-manual.pdf
When disassembling your pedalboard, be careful NOT to remove the on-board mini ROM battery as it this the one that keeps the memory settings and gt-8 firmware stored. The tricky part was to unsolder the old pot and solder the new one in. I decided to solder 5 small leads to the pcb and then connect them to the metal pot. This way, I could place the pot on the same spot on the back of the gt-8, without having to match the location of its lugs with the pcb traces(that would be impossible). Once the new heavy duty pot was soldered, I secured it in place and tested that everything works. And it did! Now the level knob is sturdy and secured in place. It's way less fragile than the old one and I don't think it will ever break again. So, if you encounter problems with your pedalboard's volume control pot, try swapping it with a heavy duty one. And if it gets a bit noisy when you turn it, just spray some contact cleaner on its back and it will work just fine. Here is the schematic diagram of the boss gt-8: UPDATE. Sorry I couldn't get clear photos using my phone. You could easily find a stereo (dual) pot on ebay or something. A small metal housing pot will fit in there and will last long(longer than the plastic ones). I used this one (you need the A50K model): You 'll have to unsolder the old pot and wire 6 short cables in its place on the pcb. These are the pcb traces where the 6 pot lugs (or the 6 short cables connected to the pot) should be soldered. Mind you, I used a A50k stereo pot and NOT a A500K one as pictured below. If you don't feel confident about this, save this email and visit a tech or an amp repair shop that could help you out. Cheers,Thanos And here are some pictures taken during the repair: Andrea Zok Dell'Aria9 ? 2013 - 8:50 ?.?. Hi! What type of potenziometer have you used. Dual Unit? 50k Ohm? 9mm? I have the same problem with my gt-8 ?? ? gothico manhathan16 ? 2015 - 1:24 ?.?. i haven't opened the gt8 yet.
I bolted the pot on the metal chassis of the gt-8. Thanos S.16 ? 2015 - 1:36 ?.?. Hello Gothico, the gt-8 can be repaired, especially by a boss dealer or authorized service. The Volume pot is easy to replace and they will not charge you a lot. Don't try to fix it yourself if you are not familiar with electronics or you may damage something else. The repair shop will have to estimate how much the repair would cost and notify you before proceeding to the actual repair. Cheers, Thanos ?? Thanos Sottos10 ? 2013 - 1:35 ?.?. Hello! Yes, it's a 9mm dual pot, rated at 50k and it is audio-taper(log). I bolted the pot on the metal chassis of the gt-8. ?? attilio mucciardi14 ? 2013 - 1:52 ?.?. hI THERE!! IT'S POSSIBLE TO HAVE THE ELECTRICAL SCHEME OF THAT REPARATION.You could easily find a stereo (dual) pot on ebay or something. Cheers, Thanos ?? Esma Ezhar20 ?? 2013 - 4:47 ?.?. Hi, do u know, how to repair my gt8 is keep on changing the sound by itself? ?? Thanos Sottos20 ?? 2013 - 11:22 ?.?. Hello Esma, I haven't encountered this problem yet. Your gt-8 has probably as software issue but it could also be the onboard memory battery. I would suggest checking the onboard 3.1V battery that's inside the pedalboard. Cheers, Thanos ?? Anonymous13 ? 2014 - 11:30 ?.?. Hello! Where can I find plastic replacement buttons (like write, or exit) for boss gt8. Mugur ?? ? Thanos Sottos13 ? 2014 - 12:16 ?.?. Hello! These buttons are custom made for Boss, so I couldn't find them on the market. There are two ways to address this issue 1) The best solution would be to contact Boss and ask them who sells replacement buttons. Maybe they can even send you a free set. 2) The 2nd DIY solution would be to remove and old button and search for a new one that has the same size and shape. Then, you can replace the old ones very carefully. Sometimes I cant get any sound at all, then all of a sudden it crackles in at full volume and frightens the life out of me.

Is thus the same issue as you mention in the top post. Thanks Garfield Thanos Sottos21 ?? 2014 - 5:30 ?.?. Hello! Yes, it could be the same issue and this article is a guide on how to have it fixed (diy or by a technician). Your gt-8 should be checked for broken solder joints or anything suspicious before you replace anything. I would check the volume pedal circuit first, clean it with some oil-free contact cleaner spray and resolder any loose joints. Cheers, Thanos ?? Anonymous22 ? 2014 - 5:47 ?.?. Hi The foot pedal on my GT 8 has become way to sensitive. I can not fully press the pedal down without activating the WAH, no matter how lightly I press. It use to require some pressure to activate the WAH as it should. Has anyone had this problem. Thanks Ray Can someone tell me if there is a way to.

Solo Switch You don't have to switch patches to take a solo with the GT-8. Each modeled amp comes with its own Solo sound, activated by depressing the Solo button. Extreme Effects The GT-8's collection of effects is truly extensive. All the effects you'd expect from a Boss multi-effects unit are here, along with simulators for sitar and acoustic guitar, as well as several synth selections. Up to 13 effects can be used at once for deep texture layering. Effects Chain Adding even more potential to the unit, each of the 13 effect modules can be configured in any order you like. Put your wah pedal before the distortion or after. Put your EQ at the beginning of your chain, or at the end. You can shape your sound with this unit any way you can with separate stomp boxes. Connectivity The GT-8 is also flexible in its connectivity. You can output to the stereo analog outs or the 24-bit coaxial out.

I was thinking Delay, Chorus etc. It was the last one. I went back this morning and bought it. Not having much experience with effects I'm probably in over my head but I figured I'd give it a try. Anybody here use one of these. I watched a couple of youtube videos and it looks pretty cool. Last time I was in Vegas I watched a Top 40 lounge band. The guitarist didn't have an amp on stage. I was wondering how he did this but now I think I know. But start a few blank presets and make your own as if they were pedals in front of you. Also the manual mode is great becasue you can make it just like a row of stomp boxes. You can get good sounds out of this. OD and Dist are not brill but useable, the rest are pretty good. You'll be tweaking and playing for hours with this Very flexible floor stomp especially with the effects loop and FX chain feature. I can use my favorite dirt pedal, put it in the loop and assign the loop sequence anywhere I want (usually before the amp models). I don't care for the COSM gain so I turn it off. Other than that a very useable unit. Spend some time over at bossgtcentral and you'll be much better off than you would be by going it alone. But start a few blank presets and make your own as if they were pedals in front of you. You'll be tweaking and playing for hours with this What I'm looking for is a good chorus, delay, lead boost, wah and maybe volume pedal. Having a tuner is also nice (I think it has a tuner in it). I really like the fact that I will have all these effects in one unit instead of a bunch of different stomp boxes.

Given the effects I've listed do you guys think that this is a good unit for would I be better off buying separate stomp boxes? You can create your own custom overdrive pedals and tweak every part of it.I used to use a GT8 in manual mode but switched over to just a simple pedal board in stead. Costs more but more authentic.but the GT8 is great none the less:AOK What one NEEDS is another question. Can make quite the difference between a nice tone or muddied up mess. Got your work cut out for you.Can make quite the difference between a nice tone or muddied up mess. Got your work cut out for you.I know, I should read the manual but I haven't even taken it out of the box yet. It's major downfall is that it's not user friendly and requires a long learning curve. Strongly recommend you join this forum which is by far the best source of info and freebies you'll find on everything Boss GT.With lots of tweaking, it can deliver and has a great layout, once you get familiar with it. The price point you got is excellent. Mine's now gathering dust since I got my AxeFx, but that's a whole other animal entirely. jon.

The number eight is considered lucky in Japan, which may be why Boss jumped straight from the GT-6 to the GT-8. Whether that's the case or not, this updated incarnation of the well-respected FX processor packs in some exciting new features and effects not found in its predecessor. And what's more, it is less expensive than the GT-6 was when it first appeared. For those not already familiar with the Boss GT range, what you get is an extremely solidly constructed floor unit with a large array of knobs and switching pedals, plus a pedal treadle for volume, wah or parameter adjustment duties. Additional external footswitches can be added to the system to increase this facility.
The main starting block is the amp and speaker simulation, and the GT-8 has a dual COSM modelling engine allowing two different amps (or two instances of the same amp) to be assigned to a patch, providing twin channel operation and various options for combining or switching amps. Hands-on tweaking of any amp sound is instantly carried out with front panel knobs controlling the gain and tone parameters. For more detailed editing of these and the effects blocks without rotary knobs (compressor, EQ, wah, FX1 and FX2), there are more parameters in easily accessible menus to be adjusted using the rotary dial and cursor buttons. For both FX1 and FX2, you can choose one from a large variety of effects including all of the more usual stuff like tremolo and phaser, plus more esoteric effects like guitar synth and sitar simulator. New to the GT-8 is a solo mode: a specially programmed variation in each of the 46 amp models that is optimised for soloing. Basically, it's a boost that you can kick in using the control pedal. Solo is great players' facility and evidence that Boss has been working hard on features to better integrate the GT-8 into guitarists' rigs. Another new feature along those lines is the amp control function that allows you to switch between channels on your amp by connecting a lead from the GT-8 to your footswitch socket. This switching can be done automatically with each effects patch or can be assigned to one of the pedals. Existing effects pedals can also be fully integrated by being connected in the external loop of the unit, which can be placed at any point in the signal chain and switched in with a GT-8 pedal. Switching from patch mode to manual mode can even be assigned to a footpedal. Sounds Straight out of the box, the GT-8's preset patches are designed to show off the unit's attributes but, overall, they have been well chosen to cover plenty of disparate guitar styles.
There are some neat switching options too that are programmed in with the control pedal - selecting channels, bringing in solo mode, turning on an effect or doing several of these things at the same time. The 46 amp models are made up of variations on old favourites - Twin, AC30, Marshall etc - and, as simulations go, they sound pretty authentic with a detailed sound that imparts the flavour of the real thing - excellent for home recording or practising with headphones. Whether you'd want to use a load of amp models plugged into a real amp for gigging is a matter of taste but, if not, there are options to set up a neutral sound or bypass the block entirely for live work. Certainly if you were to use the sims live then the solo mode and channel switching are particularly useful. More quirky, but potentially adding an extra dimension to your playing, is 'Dynamic Sense', a new feature by which you can switch amp channels in response to picking strength, playing quietly for a clean sound and digging into the strings for more distortion. As for the effects, there is some gorgeous stuff on offer. At the same time though, there are some impressive effects, potentially delightful to studio boffins, that you would be hard pushed to find a practical use for in a live situation. The GT-8 is not without duds either - forget that sitar simulator, buying a Jerry Jones is the only way. The convenience of setting up patches for recall in each section of a song is tempting but there are those, this writer included, who prefer to be able to switch individual effects in and out on the fly. To a certain extent this can be carried out from within patches by using the control pedal, expression pedal switch and other functions that allows an extra press on the pedal of a selected patch to change amp channel or switch in solo mode. However, manual mode has to be the way to go if you are a traditionalist.
As an exercise you might want to replicate your existing pedalboard set-up, in our case: compressor, two overdrive levels, fuzz, tremolo, delay, reverb, tuner, volume pedal. Using manual mode, with amp simulation standing in for overdrive and the control pedal switching channels for the two levels, we were able to assign fuzz, delay, tremolo, reverb and compressor to the remaining three patch and two bank pedals, with the expression pedal controlling volume and its switch calling up the silent tuner - job done. This was just one example but there is huge potential available in tailoring the GT-8 to suit your needs exactly and in creating some very special sounds. That said, it does require some thought and a lot of menu hopping. The amount of versatility in the unit may make it seem overwhelmingly complex to the uninitiated but a couple of hours spent with manual and machine are really all that's needed to start unleashing that potential. There are useful aids in the form of some quick settings that can be called up - so you don't need to individually program all the parameters for an individual effect or amp sound. While the GT-8 may come in a hard-wearing practical form designed for stage use, it is every bit as at home in the studio, rivalling the Line 6 POD and others of that genre. The USB connection is available in the more expensive rack mounted GT Pro, but to be fair to BOSS, cost is probably the biggest factor here. And let's face it, there is already an awful lot crammed into the GT-8 for the money. You will receive a verification email shortly. Please refresh the page and try again.
