i just joined a wedding/corporate band, and we've got a LOT of 90's R&B, so i'm in the market for an envelope filter. However, i'm low on room on my board, so it's gotta be at least regulation size, if not 1590a, which is preferable. And i'd like a blend, if possible. I've seen the MXR BEF & Aguilar Filter Twin have blends, and both sound all right, but i'm curious what else is out there. Saw the Idiotbox Bass-o-Matic, but no demos or reviews. Any suggestions?
