Thanks everyone.
The reverb is a plugin called ambience - it's the free version I'm using.
CJ - you're too much, man. Funny stuff.
The design is a hybrid of vintage circuits - with a little help from John Hinson, too. Thanks John.
Thanks Dave, yes a Musicap on the output - probably overkill - the whole thing might be overkill actually.
The DI can drive either mic or line level, and there's a preamp-out to drive a soundcard or external amplifier directly.
Output tranny is from a redd.47.
Thanks for the compliments on the rack, too - shows you what this place can do.
