Nitro effects loop volume attenuator control

[lyradguitar]

Hi there,
I was wondering if anyone could shed some light on this...When I first turn on my Nitro, the attenuator volume control doesn't seem to be working to it's full potential right away, amp is quite loud even if the attenuation is at max. After a few minutes it starts to work and the volume lowers as it should. Is it just a dirty pot? Also the tone seems to get a bit muddier when the loop is engaged even if nothing but a small high quality patch cable is in the loop. Any help would be greatly appreciated!!
Thanks! Daryl.

It may just be because the amp takes a minute to warm up. Are you letting it sit on Stand for a minute before flipping that switch to play?

Otherwise - send Scott an email or call him after 5
