Title: Bazz fuss deluxe transformer and layout questions
Post by: meffcio on December 10, 2010, 05:31:18 PM
1. Here in Poland it's rather hard to buy some parts such as the 42TM018 transformer used in BFD. But actually it is used only as an inductor. How can I make that kind of an inductor? Or maybe I can take it out from some other audio device?
2. Anyone seen the Bazz Fuss Deluxe pcb layout? Or do I have to make one on my own?

guitar pickups, small transformers from small stereos and such, contact microphones and other elements with copper coils and magnets.

Dude, I seen that page about 2 days ago, and totally forgot about it...
I've got a mess in my head. I wanted to look for the Bazz Fuss v3 pcb, and look for the inductor for the deluxe version at the same time, but why build v3 when I already have the deluxe version pcb? That's stupid. But thanks for the reminder ;p

Ok, I have some old old old crappy polish pickups, old radios, cfl lightbulb, etc, but what now? I mean which parameter is the most needed one? Do i just have to measure and find the same resistance and impedance (how to measure that sh..t with only a standard multimeter?)?

Well, I am no expert on transformers but I actually use the pickup simulator quite a bit in all different kinds of stuff. Though I can't tell you what sort of tech specs you want to be looking for, I can tell you that I have used a bass pickup and a strat pickup in the bazz fuzz circuit. Both sounded different and both gave good results. I also used a 1:1 transformer from RadShack and got the as well as the transformer listed in the schematic from home-wrecker and again they both sounded different but both gave good results. Here is another question that deserves some attention though:

You can also use the other side of the transformer from mouser to make a passive tone control that does a mid attenuator. A cap from the input signal into one end of the transformer and the the other end to ground. Using the center tap for more/less mid control. Could you use this in the bazz fuzz or would plugging a wire into ground kill all the signal?

Is there an expert among us here that can clear up both our questions?
Here is a scheme of the tone control i speak of...

I scanned this from an electronic projects book by craig anderton. It doesn't say who designed the circuit so I am guessing that is also by craig anderton.
