WAH-WAH is all that is simpler
Between a jack / output jack and a mare's
trs solid and heavy chassis which gives confidence in right away (a friend asked me what it would if I let her go on the floor: I told him that was going rpondu Bouzille my floor and c ' is true!)

UTILIZATION

I think it can not be simpler: a high pressure to enable / disable it if WHA-WHA-WHA with the expression pedals
the manual is to Get You Started gnial barbecue

SOUND QUALITY

It is pure good wha-wha screaming in acute as I like!
I use it mainly with a tlcaster and sometimes with a gretsch. (I prfre personal with the business tlcaster gots ..)

OVERALL OPINION

will be ending for a 1 year I use it and I've never needed to change the battery.
I did not try other models but it is perfect for me then ...
it's a bit expensive but good given the robustness of the pedals and chssis warranted.
why I repeat that choice? Now that I have I keep it (not insane say ..)
