I'm thinking about continuing the mods to my VM Jazz and I'm now looking at preamps. I like the form factor of the Aggy OBP-2 (trying to do this without additional routing), but not having heard one, I have no idea if it will fit my needs tonally. This is a fretless bass with Seymour Duncan Antiquity II pickups, and what I'm going for is a big, thick, warm sound, with a clear, clean, but not brittle top end. Were I to go with the OBP-2, I'd go with the two pick-up/three knob configuration, but I have no idea what the best version of that would be. Given that I'm dealing with single coils and hum, does it matter which three knob configuration I go with? I ran both an internal search and a Google search, but didn't find anything that really answered my questions.
