Less treble from AD-3208 analog delay?

[nosamiam]

I've built an AD-3208 analog delay that I am pretty happy with but I'm wanting to tweak it a bit. I didn't breadboard, so I'm not wanting to really experiment too much.

What I don't like is when feedback is turned up (I modded it to go into self-oscillation/infinite-repeats easily), the repeats lose all their bass and it gets sort of whistley. Is it possible to roll off some high end so that it loses some with each repeat, rather than gaining some. Or at least stays the same without gaining? Anybody have any ideas?

You could put a pot or a trimpot in series with those 10k resistors which are part of the LPF. (The ones just before the 2N5088s, in the upper centre of the page.)

Great! I'll give it a shot!
