Cheap delay with PT2399 module

[Domin]

Hi! I made delay pedal with this cheap module which costs less than 3€ and i put dual buffer as well, one for input impedance and second is connected to pot and module output to make blending. Is there any way to improve this module to have less dirty repeats with longer time? I know, its normal for Pt2399, but maybe there is something...

Is there any info about this module..??

if i recall there was a thread a while back about these modules...

You could use two of them in series so that you don't have to go so extreme on the pot and still get decently long delay times. Of course, like that it would probably have to be a dual gang pot, or you'd have to accept a reasonably long "minimum" delay time and only vary the time of one of them.

Otherwise, I don't see how it's possible. You can only stretch the PT2399's delay so far, and the longer it gets, the worse the quality and noise gets.

You could increase the filtering, but you'd need a schematic or reverse engineer it to see what it currently uses
