So I have an '81 Ibanez Roadster. You know the one. Looks something like this (not mine in the picture.) I had someone potentially offer me a preamp in a trade deal. I don't really need a preamp but then I thought maybe I could put it in the Roadster. I haven't the first clue how to wire it up - I could most likely have my friend help me with that. But, I'm wondering first if an onboard preamp is a good choice for this bass - specifically I'm curious to know if anyone else has done a similar mod to their old Ibanez. The preamps in question are the Aguilar OBP-3 and a Bartolini 3-band. I'd probably go with the Aggie. Anyone have either of these in an Ibanez Roadster? (or similar old Ibanez?) If so please share your experience with it. I like the sound of the Ibanez as is, but to be honest, it could use a little boost for playing live - especially for cutting through in the upper frequencies.
