Thanks, I don't trust wiring 40 of these suckers (4pin and 9pin, which can be used via the same layout) by hand, so a daughterboard it's going to be. Now, let's see if I can find someone reading this, willing to do so for a fee. €30,- is the avarage hourly wage in the Netherlands these days. 😌

Update: Someone's helping me out!

Isn’t this pretty much the same as running a parallel blender? I use one of those Sonicake Portals, before owned an OBNE Signal Blender, to mix my wet delays or whatever in. The Portal can be set to run in series or parallel.

Terribly sorry, I somehow missed this question.

A: NOPE!
It is NOT like running a parallel blender, which mixes two (or more) audio signals together — can be dry & wet (ex reverb/delay), fuzz & chorus, OD & Phaser, etc. I've known of at least one bass player who blends up to four parallel audio signals at a time.

↱FUZZ ⤵︎​
↱CHORUS ⤵︎​
DRY > Dry > > > > > > = FOUR-LAYER CAKE
↳REVERB >⤴︎​



In the scenario I describe in post #651, there is but one (1) audio path in series, and two identical side-chain dry paths whose sole function is to trigger something such as the envelope of a filter (manipulating the audio path) and/or the compressor.

So, as mentioned in my previous post, when the I have some heavy fuzz with the Quack Machine after...

...without side-chain, the fuzz compresses the signal which dulls the attack of the filter's quack (which can be a good thing for an excessively quacky circuit like the DOD FX25), but I PLAY BASS, which already dulls down the amount of perceived quack so ...

...with side-chain, I route the audio-signal through heavy fuzz, but the Quack Machine after it isn't being triggered by the heavily compressed-by-fuzz audio-signal and going "QUACK" it's getting the DRY-TRIGGER direct off my bass with all my playing dynamics unsquashed for a full-bandwidth broad-spectrum fuzzed out
QUACK!

SO it doesn't matter if I have in series OD > TREMOLO > EQ > FUZZ > QUACK > COMPRESSOR > OCTAVE-DOWN > PHASER-SYNTH... whatever the series-order, any effect that gets triggered is being triggered by the raw unaffected signal right off my bass.

A matrix mixer? Pladask Matrice maybe there is a second hand mono version second hand.

You could make that work either as a parallel mixer or as a single audio-path with side-chain triggers, but... for the latter, that's overkill and expensive for the basic splitting needed for a side-chain or two.

Even either of my two Klein Bottles is overkill.


All that's needed for the side-chain is Robert's SPLITTER, you don't even need his MIXER.

Maybe that's what people are missing here. There's no need for a MIXER, just need the SPLITTER to do the side-chain dealio.

Is it safe to assume the NE5532 on the top right is from the new process that has the specs changed for the worse? Should I just hook one up to +/- 20V and see if the magic smoke comes out?

I got a mixed bag of both kinds in a single order from a trustworthy supplier. TL072 is included for reference, from the same order. My guess is the date codes mean 2014 on the left (and TL072) and 2022 on the right but I'm not really sure. The pins look different on the one on the right. The TI website wasn't very helpful toward checking the date codes.

I'm really going to treasure the old style NE5532 since they're spec'd for 600 ohm loads.

If you don't mind SMD, check out the OPA1656.

Side-chaining is when a signal output controls a parameter of another effect. So in Feral's example the autowah and compressor would have to have a separate input for the sidechain trigger that routes to one of those particular parameters, which in the case of the autowah would be the split dry signal routed directly to the envelope follower part of the autowah

There was a pedal kickstarter a while back (edit: oh, there's still 28 available) that made sidechaining any effect easy. It's all digital, but I'm sure analog is quite feasible as well, considering the sidechain implementations in analog performance mixers.

Can I swap this hardware store rocker switch in for a standard Tayway/Tayda SPDT ON/ON? Will the high voltage rating be of concern since I'd be running a mere 9v?

There's a weird thing happening where "sidechaining" is being used to refer to something like parallel effect sends or busses - not using a signal to control the reactivity of something like a compressor or a filter, like a compressor on the guitar being sidechained by the kick drum, or a filter that uses a bandpass-ed version of the input signal as the control so that excessive lows aren't triggering it.

I've heard it as part of what (excuse me while I put on my boomer hat) seems like YouTube Mixing Tutorials, and it starts to create some miscommunication in forums.

If you want to control an effect with a different signal than the input signal, that's sidechaining.

If you want to blend an effect in parallel with your signal, that's an effects loop, effect send or bus, or wet/dry blend or mix.

Notice the empty slot on the right?

Notice only two contacts wired?

So that pictured switch will be open in one position (no continuity from tab to tab) and
closed in the other.

The middle connects to one end in a SPST 1783540824749.png and the middle connects to either end depending on which position the switch is in on a SPDT 1783540812456.png

For just open / closed that switch will be fine
 
If I 3d-printed a little parts/component drawer and then lined it with those pink ESD-resistant bags we have a bazillion of, would that protect them about as well as the bag itself?

Just thinking of ways to have parts out for more streamlined assembly. For regular storage I'm going to keep the ESD-protective bags + folder approach.
