Bazz Fuss questions

[343 Salty Beans]

Okay, I'm still waiting for most of the Trem Lune parts, so I figured I'd use the spare parts I have lying around to build the Bazz Fuss. I've got the board, I've got a box, and I just need a few pots...which should be on their way anyhoo...



And naturally, being retarded and all, I have a few questions.

1. The single pot on the vero layout...what exactly does it do? To me it looks like volume...so I'm assuming that drive is preset by a certain component.

2. So supposing that drive (or if I'm wrong, volume) is preset, what do I replace with a pot to adjust drive? I'm assuming it's that 10K resistor...but I always doublecheck online before I screw things up. I don't have a breadboard yet, otherwise I wouldn't be asking these silly questions.

3. Now suppose I'm adding the big muff tone control...would it be better to put it after the 100K pot or just before it?

Thanks in advance for putting up with me I'm still trying to figure out how to recognize stages in layouts.

Thanks a bunch for a lot of clarification.

However, I'm still confused on one thing. Is there still no way to control the amount of fuzz applied (ie the amount of clipping) without adding in another huge stage? It seems to me that lowering the voltage to keep the diode from clipping to much would kill the volume...so would another gain stage be necessary or something?

These are just my shots in the dark. My knowledge of electronics is still pretty limited.

Insert a pot wired as a variable resistor on the emitter of the transistor instead of going straight to ground. To test, I'd experiment with different resistors there to decide the value of this pot.

On that homewrecker link if you look at the deluxe bazz fuss (towards the bottom) they put a 1k pot on the transistor (to ground) to control the amount of dirt/fuzz. Should work for any version you build, although the deluxe is my personal favorite version.

Thanks, bro.

I'd like to keep it simple as possible...a) because I've already got most of the circuit on vero and b) because the box I'd like to put it in is maybe an inch tall, 3 inches wide, and 4 inches tall...not a lot of room in that sucker.

More learning experiences for me.

On a BIG side note, I was dremeling out a space for one of the jacks, and my Dremel TOTALLY whacked out on me...now it's speed won't adjust, and is stuck on super-duper high. I don't feel like sending it in, cuz that's a lot of postage/work...anyone have this problem before?

I'd recommend a darlington transistor.  The note decay gets a little too fizzy wilth lower gain trannies.  I built version two exactly as the home-wrecker schematic describes, and it is great.

sweet, cuz I've got a giant shipment of trannies, etc. coming in so I can home-make a darlington, then put that 1K to ground...and I should be golden.

Thanks a lot all

hi,
i have had more luck with a 5k-10k to ground on the darlington emitter.

Yeah, use an MPSA13 or similair and use a 100k resistor to it's Collector...just use the home wrecker schematic.
