Dirty sanchez= Brilliant design

I have this layout of the simpler, original design (which I much prefer).  The original is a filthy, nasty beast. 

- digging up an old thread...

I just built this last night, does it really need an electrolytic cap at the input? I saw other layouts with a 1uf non-polarized in that spot.

Also mine sounded kinda weak and sputtery with three NS3904 transistors. I am going to try some 5088's in it tonight to see if that brings it up a notch. I may swap R3 and R4 to bigger values as suggested in this thread.

Wow, socketing transistors makes it so easy! Found a good combination of transistors I liked.

I put a MPSA13 in Q1, a 2N3904 in Q2 and a 2n5089 in Q3. I also swapped R3 and R4 to 100k.

It sounds great now, good sustain and heaps of dirty fuzz, and no more AM radio and loud hiss

Now to build the "ultra-lord" version with the 4 knobs

Yep, socketing transistors is a great way to fine tune a pedal.

Glad the layout worked for you.  I can't find my copy of this pedal.  I think I gave it away.  I guess I'll have to build another; it is one of the nastier fuzzes I have found.
