Pretty...uh, well, I would say it's kickin' but you can hardly say that about a drone, right?
Man...I wish this build had an external pedal I/O on it. You could take this even further without a buttload of $$$ by snagging a bunch of the stranger/more interesting Chinese stompboxes. Normally, you would just use a pedal I/O...but it might also be interesting to feed the whole thing into an array of 'em. To that, you might want to see THIS: https://www.sweetwater.com/store/detail/TriParMix--electro-harmonix-tri-parallel-mixer I've had one for a while now, and it's awesome...three parallel I/Os, controls for send and return levels, phase flip, and a "tilt"-type tone control. Takes a hot minute to wrap your head around it, but once you're there, damn...and with a bucketful of Chinese stompers, it's downright jaw-dropping.
