Just dug out some old stuff and tested the RM Classic X Fuzz... Works fine with a 9v Battery...
So, I plug in an adaptor where the Battery goes and it passes the Guitar thru when 'Off'... When 'On' all I get is a Horrendusly loud Hummmm... I checked the + and - to be correct, just like the 9v Battery...
I'm stumped... I thought DC was DC...???
TIA for Ya'lls Help... :)
