Open Discussion / Re: The secret M117 flanger

This topic has already become "famous". If you do searches for anything having to do with a 1996 MXR M117 flanger on Google, the AI machine has already lifted several key pieces of information directly from my post, in some cases word for word. It's happened! As individuals we now have the ability to control the information shared with the entire world on various subjects. Maybe in the near future AI will tell us that 2+2 = 5. If enough blogs were to convincingly promote it, then it will happen!

Happy and Merry belated to all. 2025 was a total kick in the b@lls for me and the "fam"! Seems as though I've had a string of rough years. I'm not gonna hold my breath on 2026 being any better but...I'll try to keep my head up and work through it all. My recent moto has been "despite my best efforts I remain in business". It's been tough. But coming here always helps me "disconnect" and reset a bit.
Hope 2026 is better for everyone!

Sorry for being so negative.

Open Discussion / Happy New Year 2026, Pork barr...

Last post by fair.child - January 04, 2026, 05:19:55 PM

Hello folks, Happy New year 2026!!

This year, I have a personal goal to create a new chorus pedal, though the title says pork barrel which is not new. However, I do want to discuss some ideas and bounce back with you all as a starter

1. Why do I want to do it?
I always have a personal ear lust over a nice chorus and I do have an original CE-2 which is a great pedal. However, after seeing Bonamassa live and Landau often, I come to search for a blue hippo MK2, which is hard to find. So basically, because I see a lot of players that I love have BH MK2 on their chain then that's the spark on me.

2. Why Pork Barrel?
BH MK2 or MK1 is basically a CE-2 with chorus vibrato mod and I really want to go back and study again the porkbarrel or CE-2 original. Basic understanding is already there and I have built tri stereo chorus so I have a further crazy ideas (in an analog way) to start the redesign.

3. Why do another chorus design?
I want to test out the chorus LFO in a manner of slow sine wave where the rate control works not with an op-amp (triangle) wave instead more a sine wave. I know there is Vref on the op-amp network that can do that as well but I want to make it controllable using VTL5C2 or C3, or any type of slow sine wave vactrol (between 1Hz to 8Hz sinewave LFO). I think this is going to be interesting.

So there are some ideas that I write down for starters, any thoughts are welcome (if you're reading til the end thank you)

General Questions / Build doc for the original Pol...

Last post by Caedarn - January 04, 2026, 12:16:12 AM

Life got in the way and I haven't done much pedal building in the last few years. I've got an original Polytrog PCB that I now want to build, but don't have the build doc and couldn't locate it on the site. Could Brian or someone point me to where to find it? Thanks in advance.

General Questions / Re: Blue Steel LED

Last post by greysun - January 03, 2026, 06:18:22 PM

Decided to get the board going while I wait on a couple caps and resistors. Just gonna do the keeley mods - was originally gonna socket em, but life's too short.

Of course I ran out of 2k2, so had get a parallel situation going at r10 - worked great with that open space.

Trying to use up some enormous 47u electros in c28 and c27 cause I'll have a little room with the 125b and really just want them gone.

What I thought was a 100ka in my stash was actually a 100kb, and I only had a 9mm 100ka, so got creative to make that work with some perf board and leads, as well as making the 250ka dual gang - this lets me have a little play, but keeps things relatively stable when I'm tightening everything up.

Once I get the foot switch board and enclosures I'll be good to go (I even have some 10kb trimmers - BUT, if in a pinch for future, I assume a 20k is fine, it'll just be harder to hone, yes?)

Thanks again for all this!

What did you select for volume control?
Tbh those artefacts are only there when not playing, and who expects a big muff to be quiet lol?

Fair enough. It just feels louder than others I've built, but might be due to the volume pot.

I'll poke around and swap it if it's the base 10k. Nope just rechecked my board post, and I used a linear because tradition.

Logarithmic? On an output volume? Who would've thought‽ I was building it to just see if it worked first 😂 but I might could have rechecked.

Verified my board tonight. Am experiencing the 'max sustain artefacts' LaceSensor mentioned over on PPCB, but there's enough to go around without diming it.

This thing is ...gutsy. Just pushes and pushes. I want to play a bit with components and values and see what mayhem I can get up to.
