Sorry for this thread, but I've no idea where else to ask. I have Nordstrand 3-band preamp in my bass and I'm thinking to switch it to match the preamp with custom pickups local guy is wiring. The question is what is the Nordstrand worth? I think it's one of his older models and it's 5 knob (vol, vol, treb, mid, bas) + 1 switch for bypassing active circuitry (bass then works even without battery). The mids are fixed frequency, i.e. no push/pull pot. There's still [i]"that turning device I can't translate"[/i] right at the circuitry. It's in very good condition, none of pots is scratching or anything, works flawlessly. Any idea what should I ask for it? Thank you.
