UTILIZATION

The manual is well done.
Like any guitar amp, it takes time to find good settings ...

SOUNDS

I play (I try ...) mainly blues.
Difficult to play loud and clear with this amp. It saturates quickly quelquesoit modeling chosen.
Sounds more or less saturated are correct.
I did not find Jazz sounds convincing (despite my rather versatile Godin ...) or when low volume!
The effects are well done (settings quite tedious, but doable nonetheless ...).
Major flaw: the bass and midrange are very poor when the volume is mounted slightly (change the dish or opt for the XL model with its 12-inch HP!)

Changes in November 2008: I go back a little on what I said.
Always with my Godin LG now equipped with D'Addario strings to 11/50 mesh dish, I can get some nice jazz sounds reasonable amount to work alone ... (Example: http://www.valvetronix.net/preset/jazz/for-godin-lg-hmb/details_930.html ). It's less beautiful, but it still happens when I play with my partner Thurs He plays accordion and believe me chorusser "above" you have to push the amp!

Edit December 2008: refined settings, buying a amp stand ... Sounds much more satisfactory, including high volume (knowing that this is only a 30 W transistor, do not ask him too!).

OVERALL OPINION

Used for 2 years (not excessively, as I play more acoustic), I think this device fulfills its function amp booster or work for a game rather than rock but also jazz. Somewhat limited in its clear to the repeated group ...
Sufficient quality to consider to keep it!
