Smash Drive is a DIY classic built around the LM386. This is a great sounding project that is easy to build with just a few easy to find parts.

I used 9mm pots when I designed the board. After ordering the boards I realized I couldn’t source a 500r pot from Tayda. If you have problems sourcing this value you can use 1K pot and bridge legs 1 and 3 with a 1K resistor. This worked for me. See the images below.
