As requested on the forum, this is the original version of The Dane based on schematics found on one of the effect PCB sites.  A Drive only version was requested so I've done this on two separate boards for Drive and Boost, each with their own independant supply filtering and Vref components.  If you want to build the whole thing you can either do it on two boards as shown, or it should be easy to adapt to a single board, and you could even potentially make them a bit smaller by removing the duplicated filtering and Vref parts. Info about the original:    Here's what Peter ..read more

I recall reading how most of the Mudhoney DIY builds were just not sounding right.. Recently re-traced on FSB by Kasper, from his V1.1 version of the pedal - there may have been a fault with the schematics that previously floated around the web. When i saw this, i thought "the switch shouldn't work like that".. But it seems like it really does, and with this configuration, instead of the Ruetz-style mods on the Rat, one may finally get that Mudhoney (err.. tuned Rat?) tone out from a stripboard. There are the BJT transistor buffers in place to keep the topology close to an idol, but obviously ..read more

This one was recently traced on FSB and as i have a soft spot for Devi & Dwarfcraft circuits alone and together, i had to draw it up.. A bit like original Soda Meiser, or at least some revisions of it, but this time with a Chaos switch and a Drone-knob ..read more

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 bia ..read more

Happy holidays! We hope you have a good one! ...and there's number of unverified layouts for you to try out this holiday season! Like this one ..read more

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 is the loop - may it ..read more

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 re ..read more

Someone mentioned that the circuit in an earlier post would have possibly been an inspiration for this one. Not sure if i share the sentiment, since that 80's japanese design and this have basically, or in quite broad terms, just the gain pot method in common with each other. Anyway. Quite a few people seem to lke this ultra-cheap OD. And what's not to like. There's a nice, loud clipping amp followed by tuned TS-style tone control. Not that complicated, but sure does sound nice ..read more

Second post for today is the Overdrive from Manfred's trace (at FSB). This comes from the same series as it's distortion brother (see the earlier Vesta Fire Distortion post), but the design is slightly more obscure. Still, the inverting input filter path to ground gain pot method on a non-inverting gain stage is used. However, the clipping isn't your bog standard feedback loop diodes. The original diodes in series with 10K resistor are something that hasn't been identified (at least not yet), so i figured this would be a nice board to try on your stash of non-conventional diodes. Maybe some ze ..read more
