Build Reports / 1776 Five O'Clock Fuzz

Last post by Bret608 - December 08, 2025, 03:26:04 PM

I haven't seen gtr2 around these parts for some time but am still glad to post this build report. I definitely have not had time to start any new projects up since spring/summer, but this populated Fuzz Face board emerged from my stash of populated PCBs as a quick win. And it sounds great! Transistors are some old GE 2n1305, hfe of 73 for Q1 and 103 for Q2, both with leakage around 0.070mA. You know, I had always felt the whole "4.5 volts on the Q2 collector" thing was a bit oversold based on my experience with other fuzz circuits that do not live in that range (e.g. Tonebenders), and RG Keen even said as much over at DIYSB once. But I set the trimmer on this to the historical 8.2k, dropped them in, and damned if that isn't more or less where they landed (4.7v to be exact). Have to say, the volume knob cleanup is great. I also love that bit of fuzzy "rip" these transistors have at the end of a note. Josh's version of this also does very useful OD sounds due to the treble bleed mod--as you reduce the fuzz, you just turn that up to reduce the "blanket over your amp" effect.

*It's designed to fit in a 1590B with top mount jacks.

Autocorrect did me dirty.

Lol that file name. So 1590F is it? 

Jokes aside, nice work!

I'll print something kinder on the actual PCB 😘. The board is designed to fit in a 1590A with too mount jacks (of your into that).

Our repartee got me thinking about the SHO and the Speaker Cranker and how much I enjoy the sound and simplicity of operation. This circuit sandwiches the SHO between a pre-emphasis and de-emphasis stage to create an overdrive while retaining clarity. Gain staging and filter cut-offs can be set internally, then it's all rock and roll!

I couldn't bring myself to do SMD, but I was inspired to make a one knob, mosfet overdive!

Built but need to drill a box still.

Got it. Looking forward to it, but it's behind a few other projects I have to wrap up first.

Just checking in here to make sure firstly that by now everyone that ordered one received their PCBs?

Also, how are people getting on with populating / building this one?

I noticed that you changed Q2 from Ge to Si, did you try both?

I didn't test a Germanium transistor; I generally avoid them as they are both more expensive and less reliable than silicon. The mosfet boost at the front softens things in a similar fashion anyway.
