Re: VFE Windbag (delay/reverb) - volume drop/muffed sound when engaged
IC1 may be faulty. Try another TL072 or a similar dual op-amp.Bobb_Lobblaw wrote: ↑22 May 2023, 01:42 The signal going in to R1 is strong..coming out the other leg it's severely dropped and muffled. I reflowed R1, I switched R1 out for another 220K and the same vol. drop/muffle happens.
Also measure R24 (10 Megaohms).

Re: BYOC Bass Overdrive (DIY Clone) Fade in issue
...Using an audio probe I listened at various points on the board while turning the effect on and off and here's what I found: Pin 2 of Q1: No fade. Pin 1 of Q1: Fade on. So I swapped out the transistor (I originally used a 2N3904) to a 2N5088. The problem still persists. Which one is 'Pin 1' of Q1...
