Ditto! I built one, and it's absolutely the handiest thing to have on your pedalboard for a tailored lead boost. I built mine in a 1590B, but I'm planning on rehousing it possibly in a 1590BB along with an extra footswitch in for a built-in Juggler with FX loop, so I can switch it on the fly from post distortion (like I have it now) to pre-distortion, where it can really kick your dirt up a notch with a mid or pseudo-treble boost.
