i just finsihed building two Rats in 1590B2 enclosures, both with added eq controls and a relayed true bypass. One with treble & bass (BAX Rat Bass) and the other with treble, mids and bass (3 Band Rat), and they both have an additional clipping option switch. Anyway, here's a pic of each of them:
I find them a lot more versatile than a standard rat, especially for use with a bass.
