While I think possible to achieve what you want, the pitch shifter I wrote/tested was primarily done with the intention of 1 or 2 semitones up/down to not need to retune. For that use, it tracks very well and sounds quite good IMO The algorithm used for pitch shifting from the DaisySP library...

In case this wasn't a joke, this pedal is https://github.com/bkshepherd/DaisySeedProjects and the tuner is just 1 module loaded onto it. I currently have ~10 modules loaded onto it. Really cool project and the main reason I didn't just go with the terrarium from pedalpcb. I knew for a looper...

Sorry for the poor quality, hard to film and play, and show knobs Overall happy with how it is going so far! Code is here for now: https://github.com/bkshepherd/DaisySeedProjects/pull/24

I built this one https://github.com/bkshepherd/DaisySeedProjects/tree/main/Hardware/GuitarPedal125b I assume it has been discussed on this board here and there. I have an extra populated PCB (the SMT components, not the seed) of it if anyone is interested

I have a real LM308 that I could compare it to, but I understand your question based on my previous messages/timestamps! :p

I am now joining the can't hear a difference between OP07 and LM308 club :LOL: In other news with my rat, I do really like the turbo style clipping though. Glad to have a switch between silicon diodes, LEDs and neither (just opamp)

Source image inspiration :LOL:

Not sure if this is a faux pas in the build report forum to not have many words. Figured I would share a few pictures since I have never shared anything here before :) First tayda UV print came out nice, I am happy! I don't wire them for gut shots unfortunately :LOL: Full board...

Found one local to me and grabbed it, it was not genuine, nice I think I will just give up on this and stick with the op07 for my own sanity :LOL:

Yea mine was in a General Tso compressor so it was very noticable/important for me to get right due to it's role. Totally agree with @Chuck D. Bones on it's use in this application!

I also just experienced an issue with one from tayda, not sure where you sourced yours from. The issue with mine wasn't a warmness it was straight up noise and distortion/overloading/clipping/different behavior when it should not have been due to different specs on whatever chip it actually was...

Do I really want to find a legit lm308...hmm... You guys almost convinced me... I doubt I will hear a difference but also have a sick curiosity

Fun stuff then, I put a socket for the compensator cap in case I end up with an lm308, I also changed the 4.7uf C2 cap to 2.2uf and it sounds fine 🤷‍♂️ I couldn't really find any confirmation anywhere that what I was experiencing/hearing was normal, so I am glad you both say it is! It was my...

I recently built a stock rat and think this might be what I am experiencing/want to look into With the distortion anywhere above ~10-11oclock, any amount of power chords or E/drop D string, really starts to sound a bit flubby and overcompressed or overloaded. I have high output pickups and can...

Opamp technology and usage has changed too much in the past year, you would need to start over? /s

@Chuck D. Bones Can you summarize for me what the chargepump is actually offering/bringing to the Greengage (plumes) circuit (all non-inverting)? Most charge pump circuits/rationale I can find is related to bringing the voltage/gnd to 18v/0v for the opamp Vcc/Gnd, but in this circuit it is...

Don't buy all of the sludgehammer pcbs when they come back in stock 🥺, I have been waiting a month or two with components in hand ready for it! I want to replace my BDI21 :)

New OPA2134 from mouser came today Popped it in and the sound I was hearing is gone, General Tso is perfect now. I performed the same test with the unity gain setup and got 8.48mA so basically exactly matching the datasheet (vs the 0.96mA I got for whatever the Tayda chip is/was) Top is fake...

This thread was helpful to me. I just finished my General Tso build and have some strange behavior/noise that I was debugging. This lead me down to considering the OPA2134 I got from Tayda as a culprit. The photo shows a pretty poor looking BB logo (regular font?) and a missing pin 1 indent...
