Sonic Titan note decay Fizz - non Madbean

[Guybrush]

Hi all

I have recently built a tagboard version of the DAM Sonic Titan. I love the sound of the pedal but I am getting some strange note decay when a note is left to sustain. The distortion kind of farts and fizzles out before the note dies leaving a clean tone for the last few seconds of the sustain.

I've done some Googling and this seems a common problem with the LM386-1 chip the pedal uses. I've switched the chip for a LM386-4 as many suggest but this has little to no effect on the issue.

Just wondering if any of the clever folk here could offer any suggestions that might help?

Thanks

FWIW, I've had best results with LM386-3.
