Cigar Box Guitar Headquarters - CBG HQ

I had ordered a selection of 5 cigar boxes on line. Three of them will make guitars, one was given to the wife and the last one became my first CBG amp.

I had ordered an amp kit based on the LM386 OP amp. Some assembly required..... just a bare bones kit.

I have done some electronics work over the years but nothing like this since about 1985 in college. I wasn't to worried, for some reason a lot of what I learned all those years ago has stuck with me. There were some options that were explained in the notes on the schematic. I went with max gain and opted to wire the input and output direct instead of using the supplied jacks.

 With all the needed components soldered in place I prepped the box. I added a plate for the volume control and jack, put a hole in the side for an on/off switch and put a hole in the back for the speaker. I mounted the speaker in the back to save the logo on the front of the box.

The finished product turned out better than I had hoped.

With the Amp set up for max gain it works pretty well with the piezo pick-ups in my licence plate guitar, with my Peavey electric guitar it has better volume and plenty of crunchy distortion.

Can you tell me where you got the amp at and the decorative plate for the jacks.

The amp kit came from Nightfire. I used this kit http://vakits.com/lm386-audio-amplifier-kit-1695 it is available pre assembled and tested for an extra $5. They have a few different kits available,  I'm working on the 14 Watt kit now.

The 1/4" jack, volume pot and knob came from CB Gitty. I picked up the power switch at a local hardware store and the plate came from a Habitat for Humanities Restore, it was originally a decorative plate for a drawer pull.
