Operates on a standard 9v power supply. Very sturdy metal case.
A true bypass stomp switch with. Three knobs Gain, Tone and Level.
To change the battery, unscrew the bottom of the pedal with a screwdriver (not very practical) and gives you access to two mini-switches, one plays on the drive gain, the other lets you choose between crunch and distortion. So once you've closed the pedal and that like me you've screwed your pedal board .... you understand me!
New versions of Expandora have corrected the problem, the switch can now be accessed on the top of the pedal, which is much better.
The knob crachouillent with time and it is impossible even through the back of the pedal to access, so no way to put a bomb hit. Do with.
A little trick for knob who spit and you can not dismount. Turn left to right without stopping for a minute and solves the problem for a while.
Mode distortion is the sound used by ZZ Top on the album "Rythmeen" pretty gross. We like it or not. Anyway if you want this sound, this pedal is.
Nah, most owners use this pedal crunch mode.
And because this pedal is neither more nor less than a misunderstood version of the Tube Screamer. Do not laugh, this box contains-boi (little excuse) the sacrosanct JRC 4558C chip. You know, that little thing that makes the "Tube Screamer" are "Tube Screamer" since the '70s. The scheme is said to be based on an Ibanez TS.
And I made the comparison: in crunch mode with the little switch to zero, it is close enough to my TS 10. It is striking that in all cases the same family of pedal. The same type of grain, soft and warm crashing a little low but still a little more shine or nia in the treble. For the blues-rock is great. To give you an example, it's almost the sound of the riff from "La Grange" (the one after the entry of the battery). I also used to play the Status Quo on "Whatever You Want" and the intro to "Money for Nothing" that gives you an idea.
The tone corrector is very effective.
A counselor blues-rock.
I own the Expandora since 1998 and I always use it. I reserve the essentially rhythmic crunch and some blues solos. I have tried many others.
The pros: very good crunch pedal mode, in the spirit Tube Screamer, the chip that goes well, small footprint, efficient settings, true bypass, professional anything. Good value for money.
The -: crachouillement of knobs, switches and accessibility of the stack (on the old version).
