Tails bypass loop pedal idea... Thoughts or suggestions please!

[Myampgoesto12]

Hello all! Been a while since I have been on here. I'm planning on getting a new reverb soon-ish and it'll have tails all ready, but it gave me the idea to look up a way to add tails to my delay, which led to finding a couple of tails loop schematics and layouts, found one on here too.

After attempting to trace and failing to build them functionally in my cheap sim on my phone I decided to "design" my own using what I know from my own couple of builds and mods.

Came up with this



The signal waveforms seem to function the way I think they should.. so

I'm really curious about using a latching foot switch possible noise as a result. As well as the power supply design, noise filtering and such. Any help would go a long way folks!

I don't understand your diagram, sorry.

Delay or Reverb tails is pretty simple though. The basic idea is that instead of turning the delay/reverb off by disconnecting the wet-signal output from the final mix, instead you disconnect the *input* of the delay/reverb (or better, connect it to ground to prevent noise). This means there's no more signal going into the delay, but anything that's in there can still come out, so you get tails.

Not without something to push (or pull) it..
(what happens in the delay, stays in the delay..)

Yeah I didn't really describe it.. sorry.

It's a 4 Jack pedal, input on the left buffer stage(the guitar "signal" is just a sine generator in the sim, the wavy thing in the circle, then the send (to delay) in the middle area from the blue point which would be on a switch, then return and output at the green point.

The voltage source is at 14.whatever volts just to test the power supply in the sim. The ICs are to be powered by the regulated power but the sim omits those connections in the schematic by making me choose the IC power specs when placing them.

I used two ICs because at the first stage the signal from the guitar is split when not in bypass to both the delay and second stage,  and the second stage is a buffer because from what I understand tails needs to be buffered at both input and output to prevent signal loading.

I get the idea of tails, but implementing it on my own seems difficult. And I'm hoping to build this whole thing because I don't want to even attempt modding my CC Deluxe, packed full of tiny components.

Hoho sounds like it!  Enjoy!
