Everything has already been cited in prior reviews ... Because of the analog connection minimum (in, out and power supply ).... chorus or vibrato effect (+ selection switch setting depth of the effect of the right side) and playing on his foot speed .... Nothing complicated!

UTILIZATION

See previous notices ...

SOUND QUALITY

If you like Jimi, Robin, Franck, Eric ..... Go there with closed eyes by varying the speed as much as possible !!!!!!! We believe it !!!!!!
What is funny is that everyone uses it after the wha-wha, and me the opposite and I find the report much more effective!!
So: Start + + boost + roto + marshall wha-wha lamp = hell!
Small clarification though: I slowed the speed to have a minimum turnover as low as possible and simultaneously rotate max a little slower but much more realistic! To do this, simply release one or two notches of the rack shaft of the potentiometer and voila!

OVERALL OPINION

She never left me for 13 years ..... As is the ability to control speed in real time ... The least: there are certainly better, in Fulltone example, but at what cost!!
Quality / reasonable price compared with the competition even if the price of nine is not already given!
Repeat this choice?? Yes a thousand times!
