Geeze... I think we already established that I'm bad with time estimates!
Almighty... for the pickups; I'm starting to fabricate the parts needed to build them. I went through several revisions/prototypes on how to make them. They are very labor intensive, and I'm trying to streamline that. I also changed the design to allow them to be shallower so they will fit into people's basses and not require a 2" deep cavity!
This required doing a few things differently that won't impact the tone of the pickup. I'm still deciding on the best way to wire them up, since there are two different ways to do it. Actually there are a lot of different ways. I'd like people to have some options.
So this should be happening in the next 5-6 weeks.
The preamp is another matter. After working on a home brewed version that had the same features, but wasn't the same circuit, I'm now tracing the real thing (thanks to MPU). I will be making some changes to it, but it won't affect the overall function. This will take a little while, and once I'm finished circuit boards have to be made etc. So for the preamp I won't even try and guess, but it should be ready sometime in the summer.
