Here is my latest guitar rig.
Complete rig (4string home built cbg and 1.5watt battery powered cigar box amp):
It all works pretty good. The amp is very responsive and I have a gain adjustment to get a real dirty sound or I can clean it up. Volume level is pretty good for a 1.5watt solid state amp. 9volt battery supply and my strat sounds pretty sweet through it. Perfect for the cbg's. I'm working on a 7watt version at the moment. Will probably upgrade from the 3" speaker to a 5 or 6". Also working on some new steel reinforced maple neck cbg's and a fretted version. This stuff is like crack. I need rehab or something. :D
