Product Description

Double your power with BOSS's new GT-8 floor-based mega processor. Loaded with twin COSM modeling engines, it brings unprecedented performance and tonal control to the stage and studio. The Dual COSM amp section provides two discrete amp channels; you can layer and manipulate each engine independently to create wildly expressive sounds. Thanks to the Solo Switch function, lead sounds can be immediately activated -- perfect for ripping through the mix. 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.

Features
BOSS's most powerful floor-based processor!

Dual COSM amp engine allows two different amp types to be assigned to the two channels

Amp channels can be switched, layered, or panned in real-time; dynamic mode allows channel switching by picking dynamics

200 stunning preset patches and 140 user patches; 44 effects categories, up to 13 simultaneous FX blocks

User configurable effect chain; any effect can be in any order in the signal path; independent external effects loop section for inserting external effects anywhere in the signal patch

Solo switch on the COSM amp section for instant lead tone

Amp Control jack for switching external guitar amp channels

24-bit converters and coaxial digital output for high-resolution recording applications

Dual COSM amps
The GT-8 boasts the latest top-quality COSM amp models with complete dual channel configuration. Explore new sonic dimensions by combining two amp models, or by switching between them during performance. Select a high-gain amp such as Metal Stack and set it for deadly distortion. Then add clarity to the raw power by using the Smooth Drive model on the other channel. Prepare to be impressed as you tap into the expressive Dynamic mode, where two channels can be controlled based on picking strength. Transition smoothly from clean to mean by simply picking harder or softer.

Solo switch
Step into the spotlight with the new Solo Switch feature. Each of the 46 COSM amp models contains a specially programmed variation that's optimized for soloing. Simply click the Solo switch to activate the lead tone, and off you go -- it's like having a separate solo channel on every COSM amp!

Extreme effects
Forty-four effects categories are built into the GT-8. Up to 13 effect blocks can be used simultaneously to create complex textures and routings. All of your FX bases are covered -- compressors, reverbs, choruses, EQs, COSM-modeled wahs, and much more. There are 200 preset patches built into the GT-8, plus 140 user patches for storing your custom amp/effects creations. As a special bonus, there's a selection of synth waves onboard, plus sitar and an acoustic processor. From subtle to sizzling, where will you take your tone?

Effects chain
Another area where the GT-8 stomps the competition is in its powerful effects routing. Internally, the 13 FX blocks can be configured in any order you desire (for example, you can freely assign an equalizer after a distortion effect or before it). And if you'd care to take your tone "outside the box" and incorporate some external effects into the GT-8's signal path, you can do so with the Ext Loop send and return. Flexibility in routing is the name of the game.

Connectivity
The GT-8 is stocked with enough I/O options to satisfy even the most demanding pro. In addition to its stereo analog outs, it offers a 24-bit coaxial output for ultra-clean digital transfer, an amp control jack for switching between two amp channels on an external amp, an external expression/control pedal input, effects send and returns, MIDI in and out, and a headphone output.

"Pretty cool, for the $$$"
Sound: Sound quality is great. However....Depending on what type of amp you are playing through, you may be a bit dissapointed. I am currently using a Roland Cube 30. For those of you not familiar with this amp, it is a small pratice model, but sounds similar to a jc-120. The GT-8 has an "Output selection" function, designed to maximize the true sound of this pedal. I can't vouch for all of the output selections (JC-120, MS combo, etc)but the "Small amp" output leaves somthing to be desired. That aside, the effects sound awsome. Amp modeling is very good (through headphones, and probably through a larger amp than my own)The Uni-Vibe sounds very nice, as does the "Another Brick" patch in bank 24.....if you dig Gilmour's solo in the song from the same name (part 2?). "Slow Gear" in bank 79 is great...It reminds me of an Alan Holdsworth type effect, very cool...The distorions are decent, many selections to choose from. Everything from Arbiter fuzz to Rfier to MS 1970. Obviously, these sounds are not dead on, but for all intents and purposes, they sound great. If you are looking for an "expressive product" this is it man...I've had this unit for 4 weeks and I still haven't fully utilized all of its functions. I play a wide range of stlyes, and so far, I have found a factory patch that suites my needs. As far as other products in this class go, you may want to check out the Zoom G92TT, the sounds are comparable and the G92TT has USB conectivity, is tube driven (1 12AX7) and comes bundled with Cubase LE. Currently I am using an Electro-Harmonix HOG and a Synth pedal with this unit. The GT-8 has both of these features, but not in the capacity that I would like. Feature: The Pre-amp section is nice, a good tone can be achieved if you play around a little. Octave, Pedal bend and Harmonist are awsome, many ways to tweak and eq. Compressor and limiter are decent depending on which patch you use them with. Wah is lacking a bit, sounds like when you run a wah pedal straight into an amp. Uni-Vibe is balls on accurate. The Guitar Simulator function is interesting...you can combine your tone with solid body/semi hollow, hollow, chambered etc, the coolest thing about this feature: If you are playing a strat, or any other solid body, and select the Hollow body guitar sim function, you will get feedback and sustain at low levels, as if you were playing an ES-335 through an old Marshall at high volume. One annoying thing I have found about this unit is this; While in a patch, if you select an effect and tweak the parameters, you can not select another effect without exiting out of the patch and negating the changes you made to the FX parameters. Perhaps I need to read the manual a bit more...but other than this, the GT-8 is pretty user intuitive. Ah, yes!!! and the reverbs...they sound great over headphones and direct into a board. Selections include; plate, hall, spring, fender tweed, etc. Dealys are nice as well, single voice, dual voice, panning, ping pong, tap, etc. Distortions can be a bit "fuzzy", sort of like an Arbiter Fuzz Face, or a Big Muff, but over all for the price, one should not complain, with a little knob twisting the distortions sound close to authentic. The "Feedbacker" and "Defretter" functions are fun to play around with, particularly when combined with the "wave synth". Speaking of "Wave Synth"... Tracking is great, sounds better than the old Roland GR series, if you are into Pat Methany (eg. Tony Williams: Wilderness), you will probably enjoy this patch. Wave Sythn can also be tweaked, choose from Saw, Sine, Square or one or two other wave forms which elude my memory at this time. All patchs/effects can be tweaked, and EQ'd in their own right, so take your time, grab yourself a cold beer and set aside a few hours. Ease of Use: With a little tweaking you can get any sound you want. Getting a really good sound however, can be a bit frustrating at times. This should be expected though, considering that you are editing on a screen no larger than a Camel Wide. I have had no problems with compatibilty. There is a slight learing curve, but if you have used Multi-effects boards in the past, it might take you about 10 minutes to figure this thing out. Haven't read the manual yet. Bottom line, if you are looking for a mass amount of quality effects to play around with, and don't want spend THOUSANDS on individual pedals the GT-8 is the way to go. Quality: Solid built, made of metal. Knobs are tight. You could probably drop this thing down 3 flights of stairs and it would still work perfectly. Value: For the sound and features, it is a must have for the $$$ Manufacturer Support: Judging by the quality of this unit, I would assume that support is impeccable. I haven't had to call them though. The Wow Factor: Sounds great and is made of black gun metal. What more do you need??? Overall: Great unit, not a 10 as I am sure it will obsolete within a few years.

"Best Effects Pedal Ever"
Sound: Is amazing, I can't play my guitar without this anymore because it sounds so much worse Feature: It has every boss petal built into one big pedal, i havent found an effect it dosnt have Ease of Use: It took me a few months to truly figure it out (but i didnt read the manuel much) but as soon as i started to get the hang of it i figured out the rest pretty fast Quality: Its made of nothing but metal what more can i say Value: Great, and has so many high qulity effects all put in this one box Manufacturer Support: None Overall: Ill probably keep it for several more years because you can only impprove a product so much each year
