Roland AF-100 Bee Baa Layout 2Verified
Based on the Roland AF-100 Bee Baa· 6 other boards clone it
From the post
Had an old unverified layout that were pretty much trash. Got a request to build a stock Bee Baa so I drew a new layout for it. One useful mod is to raise the overall output for the fuzz section by jumper 47k and 68k resistors connecting to the Volume control on the on the right side of the board.
And per request, a smaller layout with the Boost section removed.
