: Danger!!Be careful what adaptor you plug in to your pedals!Certain pedals have different requirements and are designed to operate at different AMPERAGE(speed of
: current),Htz or VOLTAGES.If the amp value of your adaptor is higher than the amount on your stom-box,you could FRY your pedal(now it's garbage).Sounds to me that A.C. input might be damaged or an internal voltage problem.Find out which adaptor work for you.
: Good Luck

Think of amperage as a rating of draw or capacity.
If your pedal requires ( draws) 300ma, your ac adaptor
will have to be rated for at LEAST 300ma; if it's rated
for more that's cool, the pedal will only draw as many
amps as it needs. The potential problem is having the
voltage mis-matched; too low and the pedal may not work
and too high and you could fry the pedal.
