This is a Pedal Board I built to hold and transport my guitar effects pedals. The particular group of pedals I have require different voltages and current levels. There was no single power supply on the market that would provide power for all of them, so I designed and built one of my own. It provides 9VDC, 16VAC and 120VAC for an amplifier. The power is isolated and filtered, with no ground loops, so no noise ever gets into the signal path. Stained Oak and Birch Plywood with a Polyurethane finish.
