I'm interested in making a bass guitar, still in the idea stages, mostly because of a lack of moolah, the green folding stuff. Being in Australia, its not easy to get a huge range of pickups/electronics. True, I can order pretty much everything I want, but at a significant expense. So I'm keen on doing as much as possible myself, hopefully including doing the pickups too. I'm thinking of doing a passive wiring setup, using the 'my amp has an EQ, why double up' kinda logic, along with the 'thats freakin expensive, especially for a uni student' economic theory. I know that I'm not going to be terribly good at this the first time through, so I'm probly going to design them so that I am able to swap in some professionally made pups. I know a lot of the basic sorta stuff, more windings = higher output (due to more resistence) but less treble response, and vice versa. Is designing a pickup more of a matter of trial and error, because I noticed that Aero will custom make pups if you know what you are looking for. Basically what I want to know is how do I design a pickup for certain circumstances, how many windings, what sort of gauge does the winding wire need to be. Josh D PS. I ran a search but didn't find a dedicated thread, so I thought it may be useful.
