Hi,

I am having an issue when analog delays are inserted post preamp in one of the loops of my GCX.

I have a G-major as the last element before the power amp and the delays work fine but I also wanted the warmth of an analog delay.

I have the following issue with the three units I have tried (memory man, malekko 616 and carbon copy). As soon as the delay is engaged, I am getting, on top of the delayed sound, a low frequency oscillating sound. It is the most obvious when playing high pitched single notes. I don't think it is a signal level issue as I have experimented with a lower input signal at both the preamp and pedal level.

Is it a well know side effect of analog delays or could there be something wrong with my setup?

Thanks!

How are you powering the analog delays?

Hi John,

Nice to see you here again, you have always been most helpful with past issues!

I have tried a variety of methods:

Batteries
Wallwart (for the memory man)
Voodoo lab power pedal

It made no difference. Once again, what is really odd is that the G-Major delays do not have this issue at all.

If you patch the analog delay directly into the effects loop, do you get the same problem?
