Aint Nobodies Fault But Mine by Carl Wallace published on 2013-11-17T11:46:21Z The tune is an old gospel number used to demo the sound of box guitar build #18 and amp #3. It's a matching set. I found the boxes at two different thrift stores in Pasadena, Tx. Same specs as usual three strings, piezo pick up, three inch speaker and 2 watt circuit board with internal gain trim pot. You open up the amp and I wrote the directions inside. The gain, up or down makes in sound clean or nasty depending on your choice and who you intend to drive crazy today. Amp is powered by a 9 volt battery and has a surf green LED light when it's on. John Lee Hooker album not for sale. I'll sell both as a matched set for $120.
