Three models to choose from, Red, Black or Blue. All have a handy pre-gain trimmer and funky Hendrix etch.
#1 (red) is for the purists, positive ground, battery snap, no Led and a pair of high gain NKT 275 transistors.
#2 ( black) Has two high gain NKT 275s, a charge inverting IC to allow it to better work in modern negative ground rigs and blue led.
#3 (Blue) Has a charge inverting IC, blue status led and a special combo NKT 275 and a Russian UFO tranny. This one sounds a little more compressed and has a bigger range of (mis)biasing options.
