Dylan159's Boot Fuzz

2023. How the heck are we still alive.. No matter. Let's do another layout or two. This time, another nice, loud little circuit from Dylan159's Unrealeased Circuits - From the source:
Boot Fuzz. I found this simple old-school microphone preamp, and noticed the similarity with the Fuzz Face, also claimed to be based around a microphone preamp, but in this case the second stage is an emitter follower bootstrapping the load of the first for big gains. So I thought why not fuzzing it up by increasing the gain? This ends up being similar to an Escobedo circuit, but with a different, more stable biasing. 

Dylan 159's Blendy Buffoon

Next up from Dylan159's Unreleased Circuits is the Blendy Buffoon. We've had a bunch of different blend/mix/loop designs up already, but this idea was still missing. Some may have stumbled upon an issue where you couldn't use a basic blend circuit with the likes of Marshall Bluesbreaker or MXR Dynacomp. That issue is due to those pedals (and loads of others) reversing the phase. Which resulted in minimal signal output as the dry signal is 180 degrees out of phase with the wet signal. Now this one cures this behavior - and you can flip the switch to use this with any pedals in the loop - may it be reversing the phase or not. I believe this may come in handy on various situations, like recording.

Dylan159's Troupple Boost

I'll be posting a few circuits from Dylan159's Unreleased Ciruits. There was the Fuzz Facelift posted earlier and i'll continue with more of these goodies. Next up:

Troupple boost. Gamers might get the reference. This came out from my wish for a simple, clean treble boost that could work from a variety of supply voltages to be even cleaner. The rangemaster's bias varies wildly to the point that barely works at 18v. This one features the same bass cutoff and the same input impedance, resulting in that small resonant peak and treble damping. You can try a 10n cap for a more tube screamer-like response.

Dylan159's Fuzz Facelift

 It's december already!

From Dylan159's Unreleased circuits on FSB:
I'm not done with fuzz faces it seems. This one's goal is to keep all the classic cranked gain tones while making the ill-treated gain knob more useful. This is accomplished by moving the gain control to the first stage. When maxed, you have a classic, low input impedance, high gain fuzz face, because the emitter is effectively grounded. At low gain, the input impedance rises to something close to 200k or more, hopefully giving an interesting sound without the usual dulling that happens. Last but not least, this one doesn't need trimming! the emitter resistor assures predictable bias even with widely differing beta. You can still make it adjustable if you like to mess with it. Care has been taken to avoid blocking, since we're adding capacitors. With these values, blocking is roughly the same as with the original.

Update: Oops. There was a cut missing from the fuzz 3 + 100µ cap.. 8.12.2022, now fixed... and verified.
