LM386 Chip Guitar Amp

Guitar Amp based on the Ruby/Little Gem schematics.  Uses a LM386 chip to amplify the signal, has volume and gain controls, red l.e.d. power indicator, and a built in voltage regulator.  Power from 12v dc adaptor only.  I have used it with my 8ohm speaker, it will apparently work with 4ohm and 16ohm speakers as well.  For a 1/2 watt amp its surprisingly loud with a nice crunchy overdrive using the gain control.
