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? ---------- *deciBel leves considered at 1 meter from the speaker.
---------About quality------------ A friend of mine uses a tube combo (50w) and he says that it is about 9/10 It helps very much in, like you said, creating a "brain" for the rig. I have plans of doing that too... The only bad side is that you will lose some sort of "brightness" of the original tube timbre. Let's imagine you clear the whole signal chain within the pod and you are using the 4-cable method. There's only a little difference in some high frequencies, that would not be easily noticed if your ears are not in good "shape"... In an abstract, there's not much to worry about. By my own experience i can say that at live it wont change anything (how it sounds), and things will remain great. On studio i suggest you to do the obvious: nothing between guitar and amp. So, yes, you will just WIN by using the loop. ---------About how to do--------- There no great mysteries there. (as long as you're going for a 4-cable) 1. Take the "send" output of the amp and plug it in the "return" of the POD 2. Connect the 1/4" output to the amp "return" and you're good to go. If it works with analog pedals, i believe it wont be any different with multi-effects. ------------------------------------------ Fear no technology! :D
