Great stuff. Love this circuit. Love those knobs. Nice job

Awesome. Thanks for the clarification!

Is the PPCB 3 Channel Splitter and the PPCB 3 Channel Mixer essentially doing the same thing as what the JHS Buffered Splitter and Summing Amp are doing in this video? I'd much rather build something like this than buy it from them. Sorry if this was addressed before but I couldn't see it in a...

Great stuff. It was cool to see Effects Layouts give you a shout out and praise on Instagram too.

Is the PPCB wiki page down or is it just me?

That was it. Bad TL072's. Swapped out and it rules. Thanks @Cybercow

Just came to say thanks for linking this! This is great and didn't know it existed. Love it.

Good call. I did get them from Amazon so they are likely bunk. That is pretty easy so I'll try that first. I got some good ones from Mr. PPCB so I trust those ones.

I get a bad squealing/whistling when I turn the gain up at all on the Proposition Distortion. Gain knob all the CCW it does not squeal. At first I thought it could be the charge pump but it makes the noise without it in. Could it be bad biasing with Q1? I populated RB1 and RB2 and R13 exactly...

Right on. Apologies if we took the thread off the rails. I don't want to take away from the excellent layouts you are putting out there.

This is cool stuff. Thanks for posting this @Feral Feline. I've been looking to try perfboard after doing a handful of stripboard. Probably not the best place to ask this but can you recommend some quality perfboard to buy?

Nice build! Is that a black SPST footswitch?

Very interesting one here. It's a harmonic tremolo but it really has a Vibe feel to it. Gets a "chewy" pulsing to it. It sounds great. The depth knob is the key. It can really shape the tone. Component sourcing was a but tricky but nothing crazy. Got the XR2206 on Amazon and the 2N5485's from...

Cool looking diodes in D4/5. Which are those?

Thanks. Check out the demos on the site. Mine sounds almost identical. HMT-2 Page They do a much better job at demos than I will.

Thanks for that chart and info. I figured I had to dig into it more. On paper I think I should I will go with the suggested transistors. Luckily Aion Fx has them in stock

Boss HM-2 + Boss MT-2 = Dirt Monger Instruments HMT-2 I am a big fan of the chainsaws so I had to build this one. The heart of the HM-2 with the EQ of the Metal Zone. I think it sounds pretty damn good. Very happy with how it sound and looks. No complaints here. DMI makes some cool stuff.

Didn't need the build doc as all the values were all silk screened on the PCB.

I'm building the Mesmerizer PCB but I ordered 2N5458's instead of 2n5485's. They are both switching JFETs. Are the 2N5458's suitable for this circuit? Or is it picky with those transistors? From the schematic it looks like they are not biasing so it might be ok? I have the 2N5457 for Q1 and Q2...

That does make sense. I'm sure now of what to do with the ZO. I'm still not getting how the Fat Bee layout is getting 9V to the rail that it's on. I see it goes from the hole where it's marked to the CLR. But, where is the CLR connected to +?
