Spitfire fuzz schematics

[ile]

Hi,

I just build the Roger Mayer's spitfire fuzz referring to the vero layout I found from http://aronnelson.com/gallery/Martys-layouts-and-photos/Spitfire_Fuzz1.

I'm having a problem to get it work and I would appreciate a lot, if someone could post the schematic of the spitfire fuzz or send it as email to me.

When my fuzz is turned on, the clean signal goes through the circuit and the gain pot just adds some noise to signal, the circuit does not process any fuzz.

I have been trying to find the schematics with bad results. Has someone built the spitfire fuzz succesfully with referred vero layout?

Thanks in advance,

-Ile

Hi, that's my layout and it does work
If you do a "Spitfire fuzz" search, you will find the schematic in a post
from me.
Check the following with your vero build :

All the "red squares" are track "cuts" and have to be complete and clean
even a microscopic trace of copper left will cause problems.
All the traces under the opamp are "cuts"  !!
Check also that your solder does not "bridge" over any two strips of
copper, run a knife/small screwdriver between all "strips" to ensure this
and check with a small magnifying glass too

Make sure the caps are the right way around ( + is marked on the layout)
Check all the resistor values are correct and that your "gain pot" is wired
correctly for lugs 3&2&1

Cheers,
Marty.

Hi,

Ok... There was nothing wrong in the layout. I had done one mistake, when  I first time tested the pedal. There was one capacitor leg placed in a wrong hole. Anyhow I noticed that an I fixed it also before I posted here. So everything was fine in my build, except the sound was weird, no fuzz just some noise.

Then I noticed that the temperature of op-amp got pretty high and I thought there might be something wrong. So I changed it and it started to work like it should.

I think the op-amp has propably burned somehow at the moment when the capacitor leg was placed in a wrong hole...

Glad that you got it working corectly  
How do you like it now ?

I build also Axis fuzz at the same time. I compared those two and for some reason the spitfire fuzz won. The sound of axis is also pretty nice, but that wasn't the sound I was currently looking for. Axis fitted may playing style better, but I liked spitfire sound more.

For my purpose and style to play; spitfire worked better if I added some delay after it. But anyhow I like it a lot. Of course I need several weeks to learn how use it; how to get the great details of sound by different picking styles etc...

Anyhow, it works as a nice lead sound.

Next I'm going to try the ts-808 if it might be a replacement pedal for my boss sd-1. And also I need a switch box between the lead fuzz, overdrive and clean amp sound.
