Hi, I've been working on this design for a while. The concept is to create a feedback drone resonant machine, where an input signal is processed through a spring reverb. The feedback loop includes a low-pass filter (LPF) and an echo (using a PT2399 chip), which works fine. However, I'm encountering a strange issue with the reverb tank (I'm using a small Accutronics tank).
The spring reverb is audible at the output, but it doesn't seem to affect the input signal. The dry/wet control works, but it’s either completely wet (spring reverb) or dry (the input signal, which is a 5V sine wave). When the pot is set to the middle, the input signal isn't affected at all. Additionally, the feedback control doesn’t seem to have any effect, even though I can see the signal being fed back on the oscilloscope.
Any idea what might be going wrong?
