I've seen requests for this schematic in various forums for years with no responses. It would seem nobody has seen a schematic yet.
Or somebody's holding out. :hmmm:

If I had a pedal worth $1500 I'd sell the damn thing. :horsey:
BTW; just noticed Ronsound has the Mutron Flanger schematic available for $8. Well worth it, IMHO. Probably will go for it when the tax return check comes in. Gotta' pay for the Coolaudio stuff first.

It has some kind of noise gate and I like the start and stop and pedal part. 8)

Thank you Ron! :applause:
I was thinking about an old Tel Ray Morley shell.
Knobs on the top for easy access and all that...

It would be muuuuch easyer to see some gut shoots.......and closer to original one...

so what are the chances somebody really have this baby? :?
and want to take some shoots :mrgreen:

please please.... :|

p.s.
Up for auction is a fully functional and ultra-rare Mu-Tron Flanger. This is one of 1000 ever made according to Musitronics co-founder Mr. Mike Beigel. Here is a link to his website:

Mu-Tron Collection

Here are some quotes from the inventor on the design of Mu-Tron Flanger:

"The design was not that unconventional; most everyone was using a chip called the SAD1024. The SAD1024 was the chip that really let people make flangers and short-range delay lines that sounded okay. We also used a compander chip around it; but it still wasn't quiet enough for my taste so I put a very strange kind of noise gate around that whole circuit, which worked pretty good and was pretty creative. It actually made the sound a little different on the beginning and the end of notes. If there was a unique sound out of the Flanger, it was mainly because we're trying to build in dynamic range and limit noise.

"Then the other main feature of it was that we included pedal control with an oscillator control, so there was more switching. And we used a start and stop frequency control as opposed to a shelf frequency modulation depth, so that with either the oscillator or the pedal it would just go from one place where it started to the other place where it stopped, and you could shift those points. You could get the same kind of sweep as the other method; it just established the limits differently."



Controls:
Sweep Start

controls the amount of delay at the start of an LFO sweep
Sweep Stop

controls the amount of delay at the top of an LFO sweep
Sweep Rate

controls the speed/rate of the LFO wave that controls the flanger
Feedback

controls the resonance/feedback of the flanger
Effect

turns the effect on and off?
Pedal

switches between the LFO wave and the pedal as control source of the delay time
