So parts come in today for looper pedals I’ll sell. But not really happy. The bleeding is fixed with the 4PDT but there is noticeable click noise. Not a big deal if switching between hi gain fx loops but noticeable with cleaner loops.
1st Solution is try the Demont soft click switches https://lovemyswitches.com/super-premium-3pdt-latched-foot-switch-soft-click/. But they don’t make a 4pdt version, price is high and there still will probably a little bit of noise.
2nd Solution add filtering with resistors and caps
Only issue is that it will possibly change the tone and not completely kill the pop. When analyzing the pops with spectrum analyzer. The 3pdt analysis popped across the whole spectrum, the 4pdt popped more towards highs and low mids. The filtering wouldn’t completely tame it and most likely fuck up the tone. The RC filters are just never really pinpoint precise, or I’m just not an expert at it, failing to tone shape the DS-1 how I wanted, which was keep it stock with the JHS mods, but ultimately defaulting because there where probably so many filters. But definitely something I can but try but leaning on the last solution.
3rd solution is to use a relay device

This will allow me to not use the mechanical switching for the audio, which is causing the issue I think. If can I use the relay for the switching , which carries the audio, I can use the mechanical switch for just turning on the relay and maybe the leds. Audio is completely removed from the mechanical switch causing the popping sound. I can also keep the mechanical switches I have and just purchase the relays.
4th solution Use the best relay module by Lehle
https://www.amplifiedparts.com/products/relay-module-lehle-relay-true-bypass-switching-unit May be overkill for what I’m trying to accomplish, and 2 of these is pretty pricey.
Of course this is all theoretical. Will this open another can of worms? Here is an example of a clickless design. Unfortunately they discontinued the clickless version for some reason?! Think he uses a flip flop to engage relay. Not sure.
Other things I’ll change, is design a pcb that will clean up all the excessive wiring.
I can cut this easily on my cnc. Have a few copper blank pcb boards I can try. Also can’t forget to increase resistance to lower the blinding light leds. Also wondering if I can maybe cut out shapes for the LED lights. Instead of just a circle I can cutout the letter “A or B” and place LED underneath. Maybe protect the cutout with acrylic? or epoxy?
Relay not worth it?

Article states that it is not worth it. Kind of have to agree. I’d have to purchase 3 relays per box and it will probably prone to more failure. This box is going to be stomped on like crazy. My other a/b broke within a month. The one I made is going strong but I did have to retighten some jacks. On the fence on this but I’ll buy 3 of them and test them on my homemade one. The cost would only be about ten dollars in parts and redesigned the pcb board. Think I can buy 10 on alieexpress to test. The premium ones look nice. https://mas-effects.com/relay-bypass/ Nice one but cost 18 bucks.
