I've built a simple flashing circuit using a 555 timer IC, along with a 470 and 1 K resistors, a 1uF 16V radial capacitor, and a 9 V battery. The original circuit called for a second resistory (220K), but that is the one that I am using the volume pot to replace. The volume pot in the guitar is a 250K pot, and I am quite happy with the variey of flash rates I get with it. The Led's are running some fiber optics which will show up on the front of the guitar. I will also wire a switch to the circuit so it doesn't drain the battery when not in use. My problem is the volume pot also has the pickup signal running to it, and my circuit puts out a signal as well to the amp, which is the one I want to seperate after the pot, so only the pickup signal goes to the amp.
Possible? cowboy Bob, i would love to see the plan you have, to see if it would work....
