I sent them to Richard and he calibrated them. I have no idea what was actually done. Plus on the model that was made by ARP - so fixed power cord - he modded it to the original design (which works better with bass).

I'd love to know your opinion when your new Mu Fx Octave Divider lands on your doorstep. It looks very interesting!
I promise I will report. I purchased it more than anything to support Mike as I already have an original and a BYOC. But I can't wait to get it.
Better late than never... I sent Mike an email this morning. It's finally time to get this sucker working!

Remind me mate what some of the mods you did do - like what does the balance mod do? Or the Out/in switch? The rest make sense. Johnk put a level knob on my latest clone and its taking me some time to get used to, but I am sure I am going to love it in the end.
Here's mine... I’ve owned this pedal since Oct 1975 , and it went through these modifications shortly afterwards. It’s been in a box in my old gear stuff since the early 80s when I lost the power supply... which is probably somewhere here still in another box... There is no battery compartment, as its filled with pots and switches - and a stand-mount base.
I really liked the stand mount and mini toggles, as I was in a show band and didn’t have the freedom to bend down and adjust the sound and had to do it on –the-fly. I’d still like that feature.
My Mutron III was wired by a local tech in 'stereo' in 1976. By that, I mean that I had a Fender Jazz Bass that was wired like a stereo Rickenbacker bass. The Bridge pickup and Neck on a TRS Jack/Plug setup. I had the Mutron rewired to accept the TRS signal. This gave a pass-through for the Neck pickup to maintain the bottom end, and the Bridge pup was Mutron’ed. I had a balance control and TRS output. That went to 2 separate amp/speaker (8x10 & 18"folded horn) combinations. It sounded freaking awesome!
It's been gigged hundreds of times, and when I went back to a normally wired bass in the early 80s I stopped using it. I'd like to get it running again. . . ideas?
You're as into it as I am!I like "percolating," "squelchy", "gooey", "punchy" & obviously "quacky" if we are talking filter adjectives
I also like "impolite" or "mean," because a lot of modern filters are just too tame."Chewy" is good, especially when referring to the down sweep. A strong down sweep should sound like it's taking a bite out of something!
@ExaltBass
Right - sorry - should have gone back to the page!
I think I said this in response the first time but what a killer setup!
Are you able to get a somewhat dirtier tone using the "Pre" on the 3x? Is there a noticeable difference when using the "Pre" as opposed to the "Mu"?
Well in my experience with four different versions of the pedal that are in theory clones of each other (original, Lingenberg modified ARP original, Tru-Tron and 2 johnk clones) the pre-amp/gain stages feel identical on the original and the Lingenberg ARP, and identical on the Tru-Tron and johnk clones. From what john posted above the gain stage seems super simple and I doubt that there is any scientific reason behind my conclusions - maybe power-supply differences. But the my two originals seem grittier and grindier than any of the ones made in the last 5 years. With the originals that I have, the gain is always present in your signal chain unless you use a true-bypass-looper (which I don't). And I love what it adds to my sound as an always on pre. Too bad its such a pain to power and is so big. I still whip it out when for an R&B band we have around here but for everything else the modern ones work great.
Thanks, Mosfed!
I once owned a Lingenberg-serviced Mu-Tron III, and I still think my Qballs gets the closest of any modern filter to the Mu-Tron's "grittier, grindier" tone (with the possible exception of the WMD FatMan), even before engaging the Distortion. I'll try the Tru-Tron at some point, though.

Contact with Mike made. Tru-Tron3X on the way. Will pursue the restoration of my Mu-Tron III. May be a while, which is good... considering all my recent pedal purchases.

I have not been able to get dirtier tones. The only noticeable difference to me is the output volume.
On the Tru-Tron or my clones, I fully agree. The gain is not gritty at all. Just louder.

Always planned to put together a Mutron-Only board. But I keep selling them ....
Just picked up my third (or fourth, can't remember) Mutron III
And this is the best phaser ever (never tried a Bi=Phase though)
Had a Phasor I at one point too, which wasn't in the same league. And an Octave Divider.

THis is the first time Ive been over this way Mos. VERY cool thread. Im glad you started it. Ive always had an appreciation for the Mutron stuff but never had an of it. I would like to learn more about it and this thread seems like a good place to start/research. Or at the very least gimme horrible GAS attacks. DOH!
Great circuits! Thankfully these days you can find them in more user and wallet friendly formats.
I hope Mike comes out with some new stuff as well in the new format.
