Boss GP-20 Amp Factory
11 amp types
4 types of speakers
3 equalizer knobs
A gain knob, 1 for presence and 1 for the overall volume
input and output jack
A memory bank.
It's simple, but too limited.

UTILIZATION

Very easy to use because the functions are few ... Too bad there's a memory bank because you have to disrupt the knobs at every turn.

SOUND QUALITY

The sounds are of good quality and are realistic enough for most, I use mostly the "metal stack" slamming pretty even without compressor. The sounds are nice blues aussi.Branché direct the sound card is doing its job even if opportunities are limited.

OVERALL OPINION

I bought it used three years ago, it is almost always connected to my pc so I can record my ideas very fast riffs. on the other hand-no effects (compressor, reverb, chorus ...) that it is an object slightly out of date and can not be used alone either in home studio or a receiver, it must complete with effects. Too bad because the sounds were not bad, but I think today we can have something more complete (+ amp simulation effects) for less. It can not really compete with what is happening now.

Boss GP-20 Amp Factory
2 channels plus bypass pedal (not true, changes the sound, I put in a passive loop before the amp), 11 amp models each with a variation due to simulated hp but then dbrayable is okay ...
What is gnial in this pedal, and would do well to copy Tech21 is a simple three-position switch prs output: to guitar amp / power amp to most speaker / line to. So no need to touch the sounds you apniblement developed each time you change systm amplification g-nial!
No switching noise, and adjustable noise gate hidden bonus in case ..
RCA digital output is not suitable for a recorder cd-dat etc., it is pro level is ten times stronger ...
It operates on six AA batteries, it is life insurance in concert!

UTILIZATION

Well, yes and no. Yes, because everything is very clear, and the manual is well done. No, because that always has the manual handy, and the number of options is very lev. One memory is stingy, the chorus of the series in four ...
In short it is not really empty to find the shoe his foot in it, but I found clinging sounds sublime. A crunch and a lead, of course nots on a scotch under the pedal you never know ...

SOUND QUALITY

It's all good, not inflated or embellished it as GPs gear. Some restraint in the sound, but turn up the volume and it BPS just right.
This dish is that by changing my guitar while Ben is not again, just adjust the volume, but we recognize well even when the instrument.
It is a useful type pedal, pro, not powder-to-eye or I-me-branch-a-son-of-all-suite.
I use it with my bassman 59ltd 2005, pnible amp for pedals of saturax (too flashy for its own good) and it's really a very good tandem with the GP20.

OVERALL OPINION

Very useful, and what's on the bassman! The GP20 gives me the 2 channels I need without making head, and compared with DamageControl womanizer and solid metal, tube factor, simple and full of pedals (ts7, UD100, hothead, Jacques blower tube among others) to see that volume quite nice so the lev GP20 appears very very good. In crunch and lead in, something none of my other pedals is capable of.
The GP20 CHRE silent, if you find okaz in 120euros you make a very good deal especially since it does not grow on trees.
Very recommendable, even if I am quite Contrari a digital pedal fared better than the double-tube Class A on my bassman ... While on the lam!

MJ: With the RG team in Kinman GP20 gnre treble bizarre overruns whatever the amp used. It's annoying because trsdsagrable, but I did not notice This phenomenon with double windings. Try before you buy ...
