I had gone thru one of this pedal some years back, if I not wrong, it require an AC output adaptor, which is not available with normal adaptors. I had to custom make one myself.
This pedal is old skool and quite thin sounding, but can get quite good sound for some old school metal playing. Actually, I notice more than 65% of multi efx users dunno how to set their efx, and the sound normally thin to very thin sounding too.. heehee..
REMEMBER!!! DO NOT!!! Anyhow plug any adaptor to any pedal. You can fry it, and once fried, its as good as burnt toast...... How many times I see this happening. Dumb asses...
