Bah it did click, and after whawha.
Analog ...
The mine operates in 18v. And she still works as well.
by Jack, I wanted to edit this to put the Speakon, and in fact it is not practical ... Ok I'll stop.

UTILIZATION

Being able to choose its frequency range is a big advantage that made me choose it. I have one of the first model, with the settings under the pedal. No little red switch on the outside. the boost is activated at the same time as the whawha.
The manual gave some examples of sound. When we know what we want, they're going very well.

SOUND QUALITY

Bah nothing to say to myself, if I had finally been less con was young, I have the chopper power supply at the same time, instead of telling me that it also works in 9v (which is true, but file some hum ...) So today I got older, I'm finally less stupid, then that's all right. And well it may be frothing tjs saying that your guitar player is also playing with idol (NOT THIS IS NOT A SHREDDER! Adam Jones ...)

OVERALL OPINION

Bah I returned to my rig, and in fact it feels good. I try not to put across, but it sounds so good ...
