This board contains information on amp building and amp modifications. Performing modifications to amplifiers is a vastly different undertaking than rewiring the innards of your guitar.
GUITAR AMPLIFICATION CIRCUITS CONTAIN HIGH VOLTAGE POTENTIALS WHICH CAN INJURE AND KILL YOU!!!!
Those potentials may be present even when the amp is unplugged or otherwise de-powered.
If you have no experience working on such circuits, you should consult safety warnings regarding high voltage circuits before undertaking any deconstruction or modification of your amplifier. Otherwise, you'll be lucky if all you do is screw up your amp.
Know your limits. Modify responsibly. If you feel like you're in over your head, you probably are. Seek professional help with your project if you're unsure of what you're doing.
We want you to modify your equipment both successfully and safely. However, neither the staff of GuitarNuts 2 nor any members assume any responsibility for any of your shenanigans in so doing.
