Hi there folks!
I was messing around with my pod hd 500, but i had some feedback problems while rehearsing with my band...
When i'm at home, i usually amplify the sound around 65~85dB* which is a casual/domestic loudness.
When i am at a live situation or rehearsal, I frequently pull the volume up to something around 95~110 dB, and in this situations I get an annoying feedback (not the nice one usually brought by valves).
This problem, though, is not exclusive to the pod. With the Zoom G2 and G9.2tt i had, this also used to happen, although more easily. So i guess that the problem is not hardware, but tweaking.
My signal chain in POD HD 500 is:
Fassel (Wah Pedal) - Tube Comp - Noise Gate - Treadplate (4x12 Tread V-30 + SM57 on X) - Volume Pedal - Digital Delay (turned off by default)
I am using an Epiphone LP Standard.
Seems like turning off/reducing compression works for the feedback, but it destroys timbre.
Raising noise gate, at the point it already is, would decrease sustain in an enormous way.
What can i do?
