This video is a 3/4 watt, 4″ speaker model with a 100 ohm volume pot. My new amps feature a linear volume pot and dual power capability! I used to use a 1k pot for the volume, but it did not have a linear function. The volume went from low to high in about 1/16 of a turn. Now the amp works much better. The original schematic calls for a 25 ohm pot, but I believe that the 100 ohms pot works perfectly.

These are the CBGAs that have been built by me. Each one is unique, and I try my best to make each one special. As with most of my cigar box amps, I try not to deface the cigar boxes. I like to leave them as natural as possible. Sometimes I do break this philosphy, but I try my best to stick to it. Most of these are sold on eBay, and the owners have full creative rights to customize them as they please.
