Which pedal was this again?

Are there still germanium transistors in active production? I didn't know that.

I'm considering buying a Benidub Spring Amp 2. The manual says it can not be used directly with a guitar because it does not send the direct signal through, only the reverb signal, so you need to use a mixer with an AUX send. ...what's stopping me from building a very simple mixer pedal and...

A friend asked me to replace a DC jack on an EHX Holy Grail Plus - well, it's probably the DC jack, I don't have the pedal myself (yet). Anyone know if this very basic style will fit https://www.taydaelectronics.com/dc-power-jack-2-1mm-barrel-type-pcb-mount.html or if the leg position or...

LCSC is also pretty good for IC's, at least in Europe - not sure how the tariffs add up. I figured I'd order enough TI TL072's to last me hopefully forever - 50 pieces were ~15€ with taxes.

I always socket IC's, and sometimes socket transistors. I don't think it's a very big deal if you're good at desoldering and don't make mistakes. However, I use non-leaded solder and it's a pain to desolder. Where sockets shine are mostly the obvious issues, like putting parts in the wrong...

Maybe it's an anti-tracing technique? "They'll never figure which wire goes where, bwahahahaaa!"?

I was gonna make a joke about two YATS'es in a row, but it didn't sound like one. A hard clipper? Something more interesting? High Dynamic Multistage Op-Amp design makes me think there's both a gain stage and an output buffer/recovery stage done with op-amps, maybe even the input buffer if...

Thanks, I'll give that a thorough read. I was wondering if it was better to try and do the "balancing" with a trimmer/pot along with the clipping diodes, since that should help remove the difference caused by a stronger signal hitting the op-amp/buffer/whatever part of the circuit. But then I'm...

Imagine if it was "Single girls want to talk about pedals in your city" instead. Oh, the carnage.

I'll have you know it was mentioned in the opening post. Although I don't really expect everyone (or even anyone) to read the whole thing.

This is more or less what I had in mind, except with "circuit" I figured why not just go input -> diodes -> output. Yes I lose a lot of volume, but I don't think that should be an issue unless I run really close to the noise floor of my interface or something like that. As for gain matching...

Fair point, I guess by measuring I was thinking along the lines of calibrating the signal based on peak volume in a DAW, and checking whether the two signals have a different spectral balance, or if the different knee characteristics cause a compression-like effect outside of the actual hard...

And to clarify on "scientific measurements", I'd accept anything better than "just switch them out, change the gain by ear and listen to differences" since that is very easy to get wrong in either direction - any kinds of measurements might work (but what to measure?), maybe null tests? Or even...

I've been wondering about a way to test and/or measure what different diodes sound like, and more accurately if they indeed sound different when used for clipping. To elaborate, I know the biggest difference between different diodes we use for clipping is the forward voltage. To simplify...
