volume knob, "clean", high and low pass filters and gain control.
super compact size smaller than TC almost like a BOSS
I use a 12 'celestion blue, ca gouache and severe, is a 25% to 50% stronger I become deaf.
I like the clean sound ca decrease the overall level so we can ramp up without peter ears. Forgot your filter on the "sun" too keen on satu ... (Fat guy either thin or in medium with the bulk I have too much volume.)
Qd is super easy to use even
Les paul for rock (U2. .. and others) I am rather a guard has its own slightly distorted clean well. To send the large gouache is simple you need a little because the HP on a 12 rapidemment we become deaf. Do not be fooled by the size and power of the machine.
A small pb on the switch changes that make a small "tsit" on his rule on the interuptor qd.
The fan makes noise (always the same problem on the gear rack PEIT ventilos turn ities and loudly ....)
prefer a model in late 2005 with a fan with lateral recess for the screws ... less noisy.
Support for US Zvex is fantastic, cheap, fast, easy no complaints.
