UTILIZATION

I bought this pedal to be able to quickly switch to overdrive distortion. (No need to put out a pedal to engage the other)
But big problem: the equalization
Distortion in (channel 2) I use a disto acute (knob noon and medium bass and treble to full)
in Overdrive, (channel 1) that equalization is not appropriate at all, the sound becomes quite rickety, need to add bass and treble off

Therefore: I use an EQ pedal to make up for the bazaar

it's really a shame because in fact the sounds are not bad, too bad there have not EQ per channel, or at least a knob to catch up a little business.

SOUND QUALITY

used with a Guild S 300-D and a Fender Twin Reverb

by Channel 2, I am always full to the knob DRIVE. I still have the margin.

OVERALL OPINION

3 months of use.
I think this pedal was eque on estimated, may be a publicity stunt well done?
always looking for the pedal will my Drive!
