Thank you! Nope, the Standard Fuzz is a very different circuit, much more of a modified Super Fuzz. The OD850 is a modified Big Muff that has a reworked tone stack and output stage, as well as some atypical component values (330pF filter capacitors, 180Ω emitter resistors, 1µF coupling...

The Ibanez Standard Fuzz is an interesting variation on the Univox Super Fuzz. The two circuits are largely identical, with the following changes: The Super Fuzz's complex two transistor input stage is replaced with a simple JFET amplifier; The phase splitter transistor is biased using a...

In the latest installment of my Big Muff binge, I built a Violet Ram's Head. Takeaway here is that you should build one, too, if you haven't already. Build it right and you get a smooth and articulate muff that sounds good all the way through the tone control's rotation. I'm generally a...

Three orders arrived today after clearing customs on February 13. No fees on any of them.

I'll have to try that one. Are you referring to the '75 Ram's Head #1? The only '74 Ram's Head schematic that I saw in the Kit Rae archives was listed as #3.

Another amazing build! So much mojo in this one.

Thanks! They're Cliff K1C knobs from Amplified Parts.

Put this together last weekend. I used the @cdwillis schematic from this post as my guide. The Dope Priest is a great sounding Big Muff variant made by D*A*M's Emanating Fist Electronics brand with some interesting component value choices—470Ω emitter resistor on Q1, 150Ω emitter resistors on Q2...

You actually deserve some credit here—your diode data was what tipped me off to the D310.

You should post a picture of the breadboard and show us where you are connecting the red and black probes on your multimeter. It's not possible that you connected everything properly and ended up with a negative voltage on the base of Q3. I breadboarded the third stage, and you should be...

Yet another inspiring build from @Guilherme Collateral (and some inspiring playing, too)! Did you happen to record the gain/leakage/collector voltages for the transistors?

I have four orders that shipped via their cheap option due for delivery in the next couple days. I'll post an update if there are any tariff or fee shenanigans.

If you're powering the circuit with a 9v power supply and have the negative side of the power supply connected to ground, it's not possible that there is a negative voltage at the base of Q3. As an additional matter, are you sure that you have the pinout of Q3 correct? The collector voltage is...

Love it!

PM me your address!

Wouldn’t surprise me if this was a reference to a company selling relabeled NOS germanium, like the now-defunct NTE used to do.

That's actually not terrible. The hFE 63/383µA is a good candidate for Q1 in a Tone Bender Mk. II (with a 10k base-ground resistor). The hFE 107/484µA and hFE 104/512µA is within spec for Q3 in a Tone Bender Mk. III-style circuit. The others are probably useless for anything other than as...

Sounds like someone knows that they're selling junk and is trying to fend off the inevitable refund requests. Caveat emptor!

Get a bag of D9 diodes from Sovtek on eBay and you'll be set for germanium diodes. They're functionally interchangeable with 1N34A.

Are you sure that the Chinese germanium is new production? I've bought some on AliExpress and they all had date codes from the 70s and 80s and oxidized leads. (The 3AG1B in your picture have a 1983 date code.)
