That’s what she said.

I haven’t looked at the schematic but those op amp voltages look off. I’ve never seen OPA2134 ICs with that print before. Where did you get them? Could you swap for two TL072s?

That is immense @chongmagic - I’m definitely interested in building one of these. How does it compare to a hydra?

Where have you grounded the circuit? You are using insulated jacks which don’t connect to the enclosure. I would run a wire from a ground point and touch it to the enclosure and see if that makes the noise go away.

I only ever design two layer boards but I place a ground pour on both layers which can reduce cross talk between traces. That could be causing your issue. Have you also ruled out it’s not your power supply? Try it with a battery only if you can. We’d need to see pictures of the board and...

With out the mod - With the mix pot at 100% wet you get a kill dry type effect IIRC. With pin 3 of the pot clipped you keep the dry signal in all of the time and add the wet signal back in with it. I personally prefer it with the mod but you could always put it on a switch. Great builds...

I think the conclusion that often happens with talk of building a looper is that a used TC ditto looper for £40-60 is so cheap that the massive headache of a project like this isn’t worth it (for most people). I think @BuddytheReow was considering building one? Good luck if you go for it.

Hybrid tone bender?

@andare - I have a PDF with the correct font somewhere. Let me have a look for it.

Great job @andare !!! Sounds (and looks) great.

Agreed @Bricksnbeatles I think mine is better since upgrading to the hobbyist version if you haven’t done that already. I’m too committed to diptrace now to want to learn another CAD system. I find with mine that it often freezes and I need to save a project regularly just in case I have to...

It just looks the the 1st op amp stage is a Timmy and 2nd is a TS. Hardly redefines overdrive.

Great stuff Dan! I always love gawking at your designs when you post a report!

The ruetz mod is a must for me on a rat. It just takes a bit of that harsh mid range out that I don’t like. That’s what I did on my mischief machine build. With the knob all the way CCW it is great on bass and all the way CW it’s the normal rat. I have mine at about 9 o’clock. Great work as...

I like it @Gordo

I didn’t realise that video was yours @scheffehcs - I came across it on YouTube and it is very helpful.

If you look at other build reports they fit just fine but are quite snug.

That’s perfect @SYLV9ST9R - just what I was after. Thanks @Robert - I’ll give that a try too.

This looks awesome. What could be cool it to add a pot/trim to each pair of diodes in the op amp loops to control how much that frequency range is clipped. Like that the 6k8 does in the loop of a blues breaker style pedal.

Does anyone have any experience of adding an LFO to a deep blue delay style pedal or any other PT2399 delay for that matter? Fuzz dog includes a pad available in the link below for one and I was interested to see what others had done. The pad attaches into the delay pot and the resistor of pin...
