Has anyone tried this and got good results?
Very few clones of mutron out there. Would’ve loved if PP carried it.

I know they're two different beasts altogether, but I'd really recommend something based on the Mu-Tron III envelope filter, like the Fuzz Dog MOO-Tron, rather than the Vutron which is based on the Mu-Tron V envelope filter. If you're looking for a V-styled filter, I'm sure any of the available PCBs are great, but if you're looking for the classic Mu-Tron sound, as well as what I consider to be a much better filter in every way, you'll really want a III-styled filter.
Good to know!
Any chance you’ve a voltage map with 13700 IC? I pretty much traced the entire circuit for smoking Gun and I’m ready to give up.
Bypass works fine. When effect is turned on, I only get cleanish with less treble. No filter effect at all. I’ve checked wiring, component values, solder shorts and replaced ICs. I do get supplies correctly at IC pins vc 9v and vb 4.9ish. And have traced the Transistor voltages and pinouts. Using exact components per BOM, except 5088 instead of 5089. Rest are all per BOM.
Gotta check out other options from you guys .

Madbean does a better job with layouts and documentation. pcbguitarwhatshisfuck lifts Madbean's designs, poorly. Just go to the source and talent and support a better human being.

Has anyone ever successfully built one? I've never seen it
Will do in a bit. I did have to go through lot of pain to replace stuff due to troubleshooting. It is definitely not a pretty sight. Interestingly, whatever I’ve done to it hasn’t changed the behavior at all since the beginning, which means I’m not looking at the right place or something weird with pcb. I did find one of pots needs 2-3 to be shorted per schematic but are not shorted on pcb.
Even if it is not the best effect out there, I’d like to not let this board go to waste. So hopefully I can resurrect it. If not then I’ll move on to better options suggested by pretty much all of you.
Lesson learned: First check in here with the pros before taking up a non-ppcb project.
Same with the vu-tron. I haven’t seen any activity online. Although they’ve a “5k+ strong private group” on Facebook. I could go join Facebook just to get an idea about troubleshooting from that “private group”. But I prefer here and worst case I’ll Chuck the pcb and go other options.
Only thing I have seen is troubleshooting requests on aforementioned Facebook group. Only reason I joined the group was for that build. For what it’s worth, I did build the vu-tron and their master phaser (maestro phaser) which both work, but have not bought anything from them since, nor will I
Edit: the only reason I built the master phaser is because they sent me that instead of the vu-tron. Had to contact them to send me the right board

It looks bad but I’ve made sure no blobs and accidental shorts are there. Again, not my usual work style but never had so much bad luck with any ppcb boards so far.
Let me know if quality of pics is horrible. I’ll try to zip higher quality pics.
Hope I can resurrect this board by comparing your notes. Or if you see any visual obvious stupidity that I will gladly rectify.

I did try nte47 prior to that as well- which is claimed to be a direct equivalent of 5089. Those are only ones I could source in USA. I do rightly have 5087 for the pnp.
What would be the differences in the context of this circuit? Do you mean pinout wise they’re different or straight up completely different parts from functionality and bias requirements?
I’ll dig in too. 5089 is npn and 5087 is pnp. I’ve in the past successfully used 5088 in place of 5089. But this could very well be circuit dependent. Not sure.
From what in remember, 5089 is low noise brother of 5088. But maybe I missed something major in the context of vu-tron.
