Hi (again) I was getting weird feedback noises when plugging an amp in to the power station and being too close, especially when using gain pedals.
The answer I got made sense.
My question is, if I use a preamp instead of an amp, would this reduce the issue?
At the moment I have the tone king imperial head but now that it’s out as a preamp as well, I’m thinking it may work better?
Any feedback on this?

Dan, It may be a little less of an issue, but remember that it is the proximity of your guitar’s pickups to the transformers in the amp or preamp that can cause this issue and since the a preamp can still generate a lot of gain, the issue could persist. It’s best to adhere to the general guidelines of keeping your guitar away from the equipment as much as possible when playing.

Hi Dan
Gil’s right, and also check this great series of videos from Joe on how to eliminate ground loops.
When the magnetic field of your picks comes close to the magnetic field of your amplifier’s output transformer, you have made a magnetic feedback loop. This tends to sound more like a squeal than musical feedback. This has nothing to do with the Power Station or attenuators in general.
Watch Joe demonstrate the mysterious squeal here:
A second type of mystery squeal is caused by having multiple paths to ground: “ground-loops”. Most users will have ground loops and will not even …
But doesn’t the preamp not have an output transformer?
