Pedal builders REACT to this guy finally cracking the Spirit In The Sky fuzz

A local musician asked me to make him something that would do this, and it really seems to be about that last 5% of "raspberry" at the end of some of the notes and some other unique flavors. I figure some of it is the finger picking (& some gentle palm muting?), and it's possible it was a really small, crappy amp that was being mic'd too. I'm sure all of this has been discussed to death! I kinda love the mystery of it, and I certainly haven't built anything for the guy yet.

The Bosstone is not a bad guess, but it's not necessarily because of the "built into the guitar" SITS thing; it sounds like Greenbaum's was truly built into the guitar while the Bosstone was a little box that connected directly to it. Any fuzz circuit of the time could have been crammed in there.

The Bosstone never had a germanium version as far as I know, but there were LOTS of iterations, including two rather different versions from Alhambra alone - and that was before the Pasadena version and most ubiquitous Nashville ones. The very first one has tropical fish caps and a tantalum as well. The second Alhambra version was more like a Fuzzrite tone-wise, and I think there's a chance the SITS circuit might be closer to that - Fuzzrites can get pretty assy, after all. In a good way. 🍑 Mosrite was in California too, so it's possible NG's guitar tech knew Ed Sanner! Ya never know.

It's been a minute since I went down the Bosstone rabbit hole, but I'm a hardcore Spirit freak so I looked into them way before I was building anything. Here's one of the threads I had bookmarked from DAM, might be interesting. Post #33 here has more timeline pics. This has a quick demo of the trebly Alhambra V2, transitional Pasadena, and classic Nashville versions. There's also an isolated version of the song that helps you hear what's goin' on.

Transistor arrangements in each, at least according to that DAM thread:

Origin story of the bag of dicks

There were variations of the JBT built into pedal steels to emulate string swells and such. IIRC, one did use a germ for the PNP.
Those are what I was referencing.

Huh! I had never seen that mentioned, very interesting. Always liked Gooby’s version- just figured it was your standard Nashville version. The hot-rodded Bag Of Boges is pretty sweet too!

They mention a schematic of the “pedal steel” version in that thread, but the pics seem to have disappeared… Would love to see it! @jwin615 is the schematic mentioned in Post #12 of that Madbean thread available anywhere else? Nuthin there...

In this post, they seem to think it's a Fancy Fuzzbox.


"It can be found as "Fancy Fuzzbox" in any of the "101 Electronics Projects" magazines from 1970 to 1978. In 1975 they started calling it a "Fancy Guitar Fuzzbox". See here for the whole series from 1970-1981 and beyond:"


From 1970

The comment in that thread about it running on 1.5v battery made me curious. The song came out in '69, so if some guy the other guitarist knew, wired a diy circuit into the tele, it would have come from an earlier source.

Here is a very similar 3 transistor version from a different magazine from early 1968.
The Sentry Fuzz-A-Tort

Looks kinda like a Maestro Fuzz-Tone which was apparently one of the only commercial pedals that used a 1.5v AA

Dumb question: but couldn't one rig a pot to mimic a dying battery at various stages on a potential divider? or even just R1=10k, R2=2.2k (assuming ~9V) for a fixed ~1.5V? IDK maybe that would generate excessive heat.

Remember you're not just dividing voltage, also current. So you'll consume a lot more juice, most of which running through that one resistor. Better off with a regulator, maybe even just a diode.

Most of the time I see people just stick a rheostat between the 9v supply and the circuit to starve it… I’ve done it a few times too, seemed to work well. Maybe that’s not the best way..? I realize it’s just a close-enough solution for the dying battery sound, but if there’s a better trick I’d love to know.

Somewhete there's a whole thread from a while back on the "correct" way.
Though the starve pot works fine, I wouldnt go that route to emulate an AA battery.

Maybe it was another forum, or I just can't find it
There's this thread. https://forum.pedalpcb.com/threads/...variable-voltage-pedal-aka-jhs-volture.16811/

Maybe it was a debate about the approach of the JHS volture vs a starve pot. Idk. 3+ years ago...

How would you set it up if you were doing that? It’s rare that I’d need to have a 9v battery feed 1.5v to a circuit, but it would be good to know.

As for general “starve” circuits, I feel like I’ve read different opinions here and never really knew what was what. I just stuck with the rheostat! Ha

I’ll check out that Volture thread, thanks. I do remember a conversation about simply starving power vs actually emulating a dying battery.

For a non-adjustable buck, just use an LDO and build it per the datasheet example.
Like the 5v line in the FV1 circuits.
 
I lived through the entire decade yet I still can't believe the 80s happened.

I'm glad I started the thread, you guys are coming in clutch with the schematic links!
I LOVED the'80s! Everything happened for me in the '80s. I met the girl who eventually became my wife in the middle of the '80s, played in lots of bands and was part of the original music scene for most of it. We were into the alternative stuff so I never had a Kramer with a Floyd! I have a whole jumble of memories of stages, backstages, crazy hair, crazy outfits and weird music. Huge PAs. Plenty of crap but some great times too. Sigh...
