I can't believe I haven't heard/read about this - I wonder if I'm not the target audience or the PR campaign is not off the ground yet or something.

I live in Portland, OR and several generations of Sunn gear were made around here. It's always sort of been part of the scenery and local lore. Its hard for me to look at the prices on thi8s website because other than the handful of extremely sought after items that are universally expensive, Sunn gear shows up very inexpensively on Portland Craigslist, even moreso if you don't mind some dings and restoration. During the pandemic I put together a Sunn folded horn cab bass rig that I'm restoring, and also a Sunn PA system gotten for $125 (came in as a donation to the place where my kid works, and they outgrew it). Its honestly a bit frivolous in my studio to have a bass cabinet the size of a washer/dryer, so a little bit midlife crisis projects or just basking in the Oregon heavy rock energy of it or something.

I do think new generations might latch onto this stuff for the prevalence of Sunn gear in heavy and doom bands (including but  not limited to Sunn0))) but price would be a barrier for

It's been 15 years since I built this but I can open mine up and try and trace some of the spaghetti. I did all off-board wiring and had to have help from a more experienced friend at the time. There was no wiring diagram and some of the switching is counterintuitive. There's something slightly wrong with mine too- this was not a footswitch bypassed pedal IIRC, it's "always on" and it has an expression pedal input or something for activating the ring mod. On my build, sometimes on first power up I get no effect until I plug something into that jack. Still, even with a flawed distant memory and a slightly buggy build I might be able to trace connections

Hey Madbean! Been a while since I worked on one of your wiring diagrams and can't remember some of the labeling + conventions.
J1 is output right? and J2 input?
The LED - cathode is the square pad facing the SW pad right?
Thank you again!

I've gone on tour with modular synth equipment and that draws a lot of questions, including being required to power stuff up to see that it's real electronics, not prop gear concealing something illicit, etc.
Mainly just in the U.S. of course.

Hi anyone who can help, I dug a half built project from the very bottom of a project bin - Sabertooth V4. (build doc dated 2011!!) -- the PDF has no wiring diagram, anyone have clues as to the switching and LED wiring on this one?
thank you!

PS @ matmosphere if I'm not mistaken, the Maestro Ring Mod and other circuits of that period are Tom Oberheim designs but the later wave of Maestro stuff ('silver wedge box with large control wheels' era) were Moog designs. -- could be wrong?

I'll see if I still have a schem for the power supply. If not, I'll post pics of my ring mod guts with values. My friend really thought it would be best with an internal transformer but mains power is dangerous stuff that I would not try myself and feel that an AC wall wart would have been fine going into this.
I'm trying to remember what stood out as pretty odd in this project (Toppopiccione, who had a cool DIY site that I think since went offline, was the originator of this GGG project IIRC.) It starts out as a regulated bipolar PSU like in synths, so it spits out a fairly conventional +/- 12V (IIRC) but then there are additional taps out for a less commonly seen psu voltage that goes elsewhere in the circuit maybe +/-10V? Sorry it has been so long since I worked on this I can barely remember and can't guarantee my accuracy here. Also can't guarantee I still have files! will dig up whatever I can, this is really a cool sounding machine that plumbs back to the origins and basic building blocks of synthesis and Tom Oberheim circuit designs. It's stayed obscure in DIY becuase of the learning curve but deserves more airtime IMO.

The GGG one was one of my first builds (15-ish years ago) and it was very complicated, had help from an older friend with DIY knowledge, but it entailed assembling my own power supply on perf and lots of trouble shooting. At the time you could buy the PCB's from them I think. But, it has been really musically useful for me over many years. It sounds amazing, really very musical. It is the only version of the project that I'm aware of. I built it as kind of a desktop / keyboard-top module rather than as a switched pedal.

Glad to hear you're all well Gordo!
What a relief.

This coming Friday I have my first Pulmonary Function Test. Depending on the outcome of the first one, I might have to do something called a "methacoline challenge" that involves testing while asthma attack is somehow induced. On the horizon, a friend who teaches medical informatics at the state medical school, may refer me to one of their research studies on "post-acute covid syndrome". I am happy to donate my time or blood sample to becoming a data point in research, if it will help further the science about "covid long haulers."

I play this into a solid state Polytone Taurus amp with only clean channels and it sounds awesome! More "textural" than my Red Llama for lack of a better way to describe it. If I can pull the time together I'll try and post some samples but I'm reluctant to make forum members suffer through my guitar "playing" though

Gotta plug this one as I just built it from Lacensensor's trace, and it is really a keeper...First of all it sounds very different than the earlier Brown Source version that floated around DIYSB and FSB ~10 or so years ago. I built that back then and did not like it. The Brown Source has some trash talked about it online in the endless overdrive wars, but I don't see why, really -- it's just as deeply musical and responsive as any of the other Lovetones. I don't use overdrive a lot, and lean towards projects in the Red Llama family when I do, but this provides a totally different flavor.

Re: Madbean's post, I think this will be bubbling up as a major public health issue that may affect a generation of people, the way post-polio syndrome has / had.

I read an article in Wall Street Journal this morning covering post-acute covid syndrome and there was one in the New Yorker a couple of weeks ago. This is where I'm at - inflammatory response that has never gone away long after I cleared the virus. For me it comes in the form of new asthma and constant chest pain, shortness of breath. I consider myself one of the lucky ones, the WSJ article describes people with chronic GI dysfunction, chronic fatigue, and more severe memory problems, etc.
