My gear is almost all home built by me.
I got lots of help from a couple of bros here and on AmpGarage. Schematics from Sloclone.
I run preamps I built into my home-brew 2203 thru a passive loop, into my reactive load, line out into my DAW
@T Wilcox helped me build "teh Snorkler" preamp, which I use on all the Cantrell solos
