Hello, My tastes in my bass tone have become quite specific, and when it doesn't sound right to me it really bugs me. One of the key pieces to my sound is an onboard Nordstrand 3b-4a preamp in my Fender Custom Classic Jazz. I have this preamp in 2 different jazz basses (one is a backup) and have found I can't live without it which is where my dilemma comes in. I own a 1975 Fender jazz and for obvious reasons don't want to modify it to fit this preamp in the body. I really want to play this bass more, but every time I take it to a gig, I'll play half a set with it, and then pickup my other CS jazz that has the Nordstrand preamp in it because I'm jouncing for that sound. So my question is this: How can I take a Nordstrand 3b-4a (or other version of Nordstrand 3 band pre) and put it into a box, where I can run the 1/4" out of my passive 75, plug it into the outboard boxed preamp and then run another 1/4" to my amp?? Is this possible?? Easy I hope?? I have tried many other outboard preamps (Sadowsky, Darkglass, Sansamp, Aguilar, etc....) and none of them give me what I get out of the Nordstrand. Thanks TB for your input/advice!!
