Do you happen to have a schematic for Dirtbag BC108?
What’s on *YOUR* workbench?

Made some progress on this the past two evenings.

Is there such a thing as convergent evolution in circuit design? I was bread boarding some ideas and started tweaking...looked down at the revised schematic and realized I had stumbled into an all-mosfet Tone Bender of sorts.

My "T style" guitar that I built from parts finally made it back to my workbench. The volume knob was scratchy from day one. I think it was defective, it didn't seem overtightened at all. I also strongly disliked the audio taper. This is a before pic;
Finally replaced the pot with a linear taper. IMHO way better than audio. Works perfectly now and the sweep is much better. Didn't take an after pic but now it's fixed and improved.

Does the world need another tonebender where you have to order 50-100 obsolete transistors from the far reaches of the earth just to get a few in spec?
I, for one, welcome our new mosfet overlords!

Damn straight it does!

A MOS-Tender? No. No I don't believe it does.Does the world need a mosfet Tone Bender?

I'm using BS170s. I don't know for sure, but it would probably take 2N700s with zero changes. The bias network is just different enough that it should be less sensitive to variations in transistor beta.
it is a little different. It does the bloated histrionic thing that FF and TB circuits do, but it has a certain grind to it that means it can chug as well.
There's no accounting for taste, I guess.
P.S "Moss Tender" sounds like a cousin to the Ents.

Finishing another batch of Morpho Chorus! Guess I’m going to hunt for more MN3007/3101 soon

Damn dude. Your pedals are truly beautiful. How does this one differ from your Demoiselle Chorus?Finishing another batch of Morpho Chorus! Guess I’m going to hunt for more MN3007/3101 soon

Thank you! The Demoiselle uses the MN3207, the rate control goes way faster (47nF capacitor instead of 100nF) and it can do vibrato only (with the D/C/V control all the way to the right). I’ll record a side by side demo, the chorus is a bit richer with the MN3007 and the noise floor is lower on the Morpho.

Hey I built one of those. Careful my board was backwards. The pot needed to be on the component side. Or else everything runs backwards. I still haven't fixed mine.
