Here’s a mod for Jaguars that I done a long time ago. Some may find it cool; I like it.

Another one for the collection. Details of its origin are at the bottom of the 'Write-Up' tab on the attached Spreadsheet.

Anybody have the schematic for a Dunlop Univibe UV-1 Rev F? I'm not getting the effect signal when engaged, only getting bypass. The light is...

This one has become very popular among bassists. It's extremely similar to EQD Speaker Cranker. I've read people claiming that this one is a lot more...

I really hate spam

...and the units keep on coming!!! This is from the September 1979 issue of British publication Practical Electronics . It's different from the...

This is a circuit I've had from something I photo-copied 40-odd years ago. Basically, it's a Fuzz unit, but with a few bells & whistles .
I've...

Good! I am building a Boss TW-1 that I had bought disassembled, I have put the missing parts, but when activating the effect, it does not make the...

Not a vibrato really but a good sounding tremolo.

Hi,

I have some questions about the tweed man overdrive ( from pedalpcb.com) which is a clone of the Catalinbread formula 5F6.
I have just made it...

I took some gut shots when I crossed paths with one of these pedals a while back. I drew in the tracks and mirrored this to make a combined image of...

hi all,

haven't finished tracing this one, but something is immediately clear: this reissue isn't based on the dod 440. I remember back when the...

I’ve got an issue with my small clone clone. It’s not passing signal, but the output has a chorus effect on it, so it’s looking like the first opamp...

I've always liked this Popular Electronic Fuzz circuit because it had the waveforms:

Even in 1968, you could download (with paper en pencil) a fuzz schematic in the local public library:

I built this circuit and modified it from the MXR M108 Vintage Bluebox. Want to know if it was written correctly?

Hi

I've been working on this idea for a while, trying different designs to mix together an overdrive and clean signal using a dual gang pot.
It...

I couldn't find any record of anyone cracking open a Bass RC Booster, so I did one along with the AC and RC traces. (They all share the same PCB, so...

I have more extensive gut shots of these two pedals. If anyone is interested, I'll attach them also.

I cracked up a Joyo Signature Overdrive, a...

I saw some speculation that the Caline White Heat was a DOD Overdrive Preamp 250, so I found a schematic and compared it to the circuit board, but it...

I really like this pedal. I’ll work on a schematic in a bit but here’s pics for now. I’m wondering what it’s derived from.

It’s very warm (no...

Hi,

I hate to drag up an old thread so here's a new one about the same with some questions. I haven't built this yet but am working on a mix of the...

Does anyone happen to know anything about this stereo OD pedal from the late 70s? Sounds and looks interesting.
