Glad your enjoying the preamp as it is, simple is good. Now for that power amp project of yours,
those heatsinks look like it's ready to put out some serious wattage. Do you have that build going on another thread?

no, not yet
but its from apexaudio's '1000watt Simple PA Amplifier'

well, I really dont need it, but since I already got most parts, why not try it
besides, it might be fun to have such a power monster

Hi Tin, I actually thought you mounting your fet preamp into your bass to make it active. But saw from your other post that it is some pickup rewiring.

sorry, I got busy, and was confusing

broke one coil wire, but managed to fix it, and it works ok again, in parallel

nah, I hate batteries, and prefer passive

like said, it works fine again
and I like the parallel pickups too
but had to change tone control cap
or else it was way too bright

found a wire had been jammed by magnet
and I broke one coil wire
I suppose it burned from too many solderings, when testing the different configurations
not all worked well
(as a warning if you try this)

Hi Tinitus, yes those really small wires can be tricky. I avoid touching them if at all possible. If I do I rewire the other end of the cable connections with a switch. In my case it's a 5 way switch for strat style 3 pup. While you have the pickups out you may want to look at the shielding inside the cavity of the bass. Get some copper tape and line the insides, as well as the cover, and connect to your jack ground. Should be a big improvement to reducing hum and interference.
