I don't have one, but there is talk on many forums yet I haven't heard one bad word about Erich's stuff.

I also emailed him once, and for the Muff Divers he says he uses rugged NOS Phillips transistors with a Hfe of 500, but would not say the particular model which I found kind of...strange.

You can see them here on the left:

And a few gut shots I've collected:

One of these popped up on Devi Ever's forum for sale.

Looks like BC327 transistors. I'll have to give those a try in a Muff.

BC327 are NOS Phillips Rugged transistors??? yeah...right... I have a hole bunch around, they are as common as dirt

Is this just a modified muff?

Of course it is. The "rugged" transistors are just BC327s - they have a high Vce, I suppose, but they're not particularly "rugged".

BC327: Vce= 45V
BC 560 (BC 550): Vce = 45V

Battery Voltage: 9V

I dont think I would describe a transistor as anything other than rugged. Rugged just mean its not going to have a mechanical failure in most cases and I have never seen a transistor fail for mechanical reasons.

The wiring looks like vomit. How do they have that board mounted? A dab of glue on one of the pots? :lol: Cheap shitty New Sensor boxes and cheap shitty parts. Vomit paint job. What a piece of crap.

The thing I don't get about fuzz pedals with a bunch of switches is each so called pedal they switch into functions half ass. "24 pedals in one"? :roll: I guess this thing could be useful in one way. You could find out that you prefer their crap version of a Tonebender over the rest of the switched in "pedals" and then sell it and get the real thing? You're most likely going to find one setting you like and leave it there anyway?

Cornish muff? Not even close. :applause:

Don't even post a schematic for this piece of shit. It's not worth soiling the carpet over. :lol:

Thank you, my pleasure.

I don't think I'm being too harsh. They want $250 for this box of shit? :shock:

What kills me is that he doesn't even bother to make a decent label for the things. If you pay over $200 for a pedal, it had better look good! These things look cheap cheap CHEAP! I honestly don't know how they sell... I thought good looks were the #1 selling point on boutweak pedals.
I'm obviously trying way too hard... since it doesn't require any actual work to build something that sells... just copy whatever thing (preferably a fuzz...) that is popular.

...and how is lifting the diodes on the second clipping stage of a Big Muff supposed to turn it into a Tone Bender? :roll:

My tracing is slightly different and shows a 22k collector resistor on stage 1 and 3.

It should be. I found that you also have to reduce the gain of what was the first clipper stage to make it sound like a Jumbo Tonebender. I had a 100 ohm resistor at each emitter, and increased the one in the first clipper stage to 330 ohms when switching to JT mode. It really wasn't a big enough change in sound to bother with . The JT had lower sustain, but the overall "voicing" wasn't changed. I gave up with it, and used the second switch on the box to switch in a clean compressor before the Big Muff, or on its own when the BMP was bypassed.
