I have a friend who want to turn his Vox Amplug into a pedal - says he likes the AC30 tone he gets from it. The Amplug (as seen here: http://www.voxamps.com/amplug/#page_specifications) runs off of 2 AAA batteries, or 3V.
Is it possible to use a road rage board (or something similar) to actually drop the incoming voltage to 3V? What would I need as far as IC/regulator for that? Thanks friends!
You need two capacitors, a tiny strip of vero board and a 78L03. Look in the data sheet and you should find a general schematic to make the Vero. 9 volts in on one side and 3 volts out.
If you get a chance post some gut shots of the amplug. Just for curiosity sake. ;)

Josh - you know I will! ;)
Jake - is the following schem correct? It's the closest I found to what you described. Not sure why it specifies tantalum...

Exactly :D
it will just be a 3 strip piece of Vero. Two capacitors connect the outer two tracks to the center for ripple filtering. Just connect 9 volts to the input lug, ground is the center lug (usually, you may want to double check as my track record for this is pretty bad ;D) and the output lug will give you 3 volts. I usually use bigger caps than that though, mostly 1-10uf I think should be fine.
