[WIP] PedalPCB SideEffect Relay Bypass Module

Asking for a friend I see

Let's just say I acquired two cream-colored enclosures at a closeout price that may or may not have been decaled and drilled at the time of purchase

Another option would be pairing an EQ with any dirt. The order flexibility would be useful, and a solid EQ (graphic or parametric) is such a simple and impactful way to voice distortion/OD.

 

[Robert]

Absolutely. One of my first personal projects will be some form of dirt with a switchable one band EQ in front to boost the midrange through the roof.

Exactly.

Careful though: A neutral OD/Distortion with pre-gain bass emphasis / active mids controls paired with an active EQ would make over 200 pcbs redundant...

How about a doom pedal called the ED-209? Like, it starts off sounding really good…but eventually falls flat.

This is very cool! I think the momentary function on the VIIB board is really perfect and this gives that option for a lot more builds.

Will switch pop be a concern for high gain circuits activated on the momentary side? I'm thinking about the differences between true-bypass and buffered modes in the VIIB.

Maybe a Mercurial Boost?? Seems an ideal way to put an otherwise unused pedal into action.

I just discovered this thread. Pumped!

For combination ideas: I love putting a sub-octave in with a fuzz. Imagine pairing a Captain Bit with a Bayonet Fuzz? (Or Corduroy Fuzz, or pick-your-favorite.)

Also love throwing in auto-wah effects where they don't belong. Phaser + Distortion is always a favorite combo.

Possibilities = endless. People are already thinking about putting 2 Salvager 9k relay bypass modules in one box, I'm so sure.

I missed this thread the first time around. My brain just exploded.

Another possible use case:
Use momentary mode to activate the 2nd channel in the FreakZEQ. Oh, @!#?@! yeah.

Hmm Use the second relay to control switching between two pots — as mentioned earlier, delay feedback, reverb swells, spiky-trebly breakdowns on bass, "AM-Radio" EQ on intros outros...

I'd forgotten about this little MUST-HAVE.

 

[Bricksnbeatles]

any updates on this?

 

[Robert]

Just need to finish up the code.

Very cool! Is the switching of the relays done via the 2n3904? Or are these for switching the LED? The 2n3904 don't seem to be used on the through-hole version?
And why two big caps? One before and one after the voltage regulator?

As you can tell I'm very interested in learning more about the circuit

@Robert any chance this and/or the intelligent DPDT boards will be available soon?

Just need to finish up the code.

How’s that coming along? I just happened to run across this and it looks awesome.
