Menatone - Howie

Hi.
I own a Menatone Howie ( the latest version with a clean and a drive channel )
It´s a dumble-in-a-box pedal and it sounds great.
I could draw a schematic and shoot some pics, if someone is interested.

For sure, we are interested!

Okay!

I would have to desolder many parts to draw a schematic. If you want some special pics, let me know

Hi folks,
This forum gave me so much information.
This is my way to say thank you

Thanks a lot!!!

Thanks!
Drain and Source of the 2n7000 (Vg and V- in your schematic) are referring to nothing. Maybe Vg goes to Q2 and Q3 trim pots? Thanks again

hey torben, thanks a lot!!

I redraw the schematic at this moment for better reading

nice to see mr. mark hammers SWTC...

regards, kusi

@ ik6gpy: V- goes to the DC-jack or battery-
Vg goes to the output-jack (it´s that little green wire)

here my redrawn schematic, please let me know if there are any errors.

torben, could you messure the drain-voltages if you reassembled the circuit? thanks a lot!

regards, kusi

Great info guys! R17 = 47M ohms! Whoa, I think that is the largest value resistor I've ever seen in stompbox...

That's a lot of self-biased JFETs.

that's gotta be 4.7M, right?

No, it's actually 47M. If you have a look at the real #124 Dumble Ods schematic you'll see the same values on that stage.
