high resonant "feedback-ringing-decay" with delays @ highgain patch

[grax]

i guess this is not a bug so posting it here:

rehearsal situation - axefx2 - vht2902 into 4x12 & 2x12, all mono:
when using high gain patch (dizzy ch3) with a very simple delay (digital, mono with approx 1,5 "repeatings") I get a kind of high resonant feedback ringing delay "decay" sound, which is audible right after the delay repeatings should have already faded. It is not that loud but clearly audible and sounds also a little bit "flangy" (hard to explain this better).
This happens at reasonable volume levels, we have a loud drummer.

Anyone experienced this?
Is this a basic (physical) problem due to high volume settings?
Any tricks to prevent it?

(I cant send patches because my axe is 25 miles away @ rehearslroom, anyway i think there is nothing special about this patch, really basic ampblock into delay)

Thanks for help!

What kind of delay is it?
Where do you have it placed?
Have you considered just using the dual delay with no feedback to have exactly "1.5" repeats?

-digital mono delay (will check the settings next time in rehearsal)
-located after amp block
-no, didnt try this, will check this up, tnx matt!
