I got a guitar a while back, but no amp to go with it. So I decided to make my own practice amp mostly using electronics parts that I had lying around. The amp cabinet is based on a vintage Fender Champ (5F1) practice amp that was introduced in the 1950′s. For my version, the cabinet is constructed from a single select pine board and joined together with finger joints. The speaker panel is 1/2″ plywood and holds a single 6″ speaker. The back panel cover pieces are 1/2″ birch plywood with edge banding on the tops. The cabinet is finished with Minwax golden pecan stain and two coats of tung oil.

The amplifier section is my implementation of the Noisy Cricket Mark II schematic from Beavis Audio. The Noisy Cricket amp is designed around an LM386 1-watt audio amplifier chip that is intended for clock radios, boom boxes, etc. The amp circuit is constructed on a small project board with only a few resistors & capacitors as support components. The three knobs control volume, gain, and tone. The switches control power and grit (distortion). The amp is powered from a 9v battery.

To my ears it sounds pretty good. Here is a video demonstrating the Noisy Cricket amp:
