Paging resident diode guru @thomasbe86

I don’t know about protests (the almost never have any actual impact and when they do have an impact half the time it’s the opposite of what the protesters want), but there are at least three serious lawsuits that are working their way through the courts—V.O.S. Selections v. Trump, Princess...

I emailed them ten days ago and never heard back.

This really isn’t comparable with JLCPCB or any of the other Chinese PCB fabricators. A few months ago I decided to build a clone of the Mountainking Megalith, so I whipped up a PCB and had JLCPCB fabricate it, which cost $3.71 including shipping. The entire build cost just under $30, including...

This is indeed a thing. The Tone Bender Mk. III/IV family tone control is backwards compared to a Big Muff and most other drive pedals. If you want, you can swap lug 1 and lug 3 on the tone control and it will work in the opposite direction. It’s possible that your germanium transistor might...

If I recall correctly, the PNP transistor is part of the octave generator, which in turn is a copy of Tim Escobedo’s Push Me Pull You octaver. Someone else used a PNP germanium transistor in their Push Me Pull You and I think that it sounded pretty cool:

As I explained in my earlier post, the red mark designates the emitter. The middle leg is the collector and the remaining leg is the base. The PCB footprint uses a different pinout. Unless you twisted the legs to match the PCB footprint, you will need to switch the base and collector legs, as...

Well, this is a bit late, but here's the BOM. Value Name Value Name C250k BASS 47n C1 C1k FUZZ 5n6 C5 C5k GAIN 5n6 C11 A100k LEVEL 4n7 C9 B100k MIDRANGE 4n7...

It looks like you’re using a Soviet germanium transistor. Which one? Many of the ones that are good for Rangemasters have a different pinout than the footprint on the PCB. If it’s a GT308 or P416, then the red dot marks the emitter, the middle leg is the collector, and the remaining leg is the...

Have you noticed any difference in noise levels by grounding at a single point vs grounding at both jacks?

Try resoldering the wire connecting the negative side of the DC jack and the PCB. Lug 1 is connected to ground, so you should be getting something close to 0Ω between the negative terminal of the DC jack and lug 1. Edit: Try the diode setting on your multimeter. It probably has a secondary...

Really?! I didn't know that they made multimeters without a continuity test function. Can you also post a picture of your multimeter? In the meantime, try measuring the resistance between lug 1 and the negative terminal on your DC jack. If it's ~0Ω, then there's continuity. If you get a really...

The don’t have a US location as far as I can tell. Tayda used a freight forwarder that was based in Colorado as their economy shipping option until 2022ish, at which point they changed their shipping to the options that they currently offer.

They’ve added faceplate engraving/cutting/printing, too.

What happens if you do a continuity test between lug 1 and the negative terminal on your DC jack?

Looks like what JHS calls the V3C “no brackets” version, as the control and jack labels are not placed inside of boxes. Based on the foot switch date, I’m guessing that it was built sometime between mid-1987 and 1988, when the PCB was redesigned and the LED was added.

You did a great job on this one. I love the touches of yellow on the dauber and their echo on the yellow knobs.

Welcome to the forum! If you post the PDF that you uploaded at Tayda, one of us would be happy to take a look at it for you and see whether we can spot any issues.

Does the Vf change if you hold the diode between your fingers? If it changes, then it’s germanium. If it’s the same, then it’s silicon.

Depends on the fuzz. I’ve built Tone Bnemder Mk. II’s with Q1 and Q3 that leak 500-600 uA and sound phenomenal. Likewise, I’ve used AC187 and GC521 transistors that leak over 1mA in Tone Reapers, and they sounded really good, too. I’ve heard of people using extremely leaky transistors for some...
