HELP!! USA>UK Converter Buzz - PQ3 + HUSH

[ol753]

Hey all.
I'm in the UK and incorporating 2 pieces of USA gear into my rack. A Furman PQ3 (reissue with input on front) and a HUSH Rack Guitar Silencer

I bought a USA>UK power converter to be able to power these in the UK, but no matter what I do, or where I put it in the rack, there is a HUGE buzz from it even being plugged in. I've gone through all different possibilities of turning the PQ3 and the HUSH off to see if their proximity to anything causes the buzz but it isn't. As soon as I take the adaptor out of the equation the sound is drastically improved. There is a USA 6-gang extension plugged into the converter to power the PQ3 and the HUSH.

Does anyone have any tips for what I could do to power these in a more efficient way. It's quite urgent

The adaptor says
"Input: 230V / 50Hz - Output 110V / 100VA"
plugged into a USA 6-gang extension (which I power the PQ3 and HUSH from)


my rig is as follows

Fender EVH 5150III
Furman Power Conditioner
Voodoo GCX
Voodoo GCP
Voodoo Control Switcher (for amp channel switching)

Guitar>
Furman PQ3
Guitar Silencer
Micro POG
Homebrew Mini CPR
Homebrew Powerscreamer
>Amp In

FX Send>
Homebrew Mimic Delay
MXR 10 band EQ
>FX Return

PS - What is the "right" way to put the EQ and Delay in the FX chain? I always thought putting the delay first is "right".

The PQ can be noisy on its own. It has a pile of gain and drive. However, if I recall, this has a two prong, ungrounded plug. You have this competing with the rest of the grounded system. Those converters aren't top shelf either and it can probably contribute to the problem. Sometimes a HUSH can create more trouble than it is worth.

Two things I would suggest is to run the PQ through your GCX and in the FX loop, instead of up front. Ditch the HUSH for now and take it out of the equation. Also, try a more industrial grade power converter/conditioner/regulator that will allow you to input to wall power and put out both 230 and 110. Plug your complete system into this. That way, everything is coming from one ground power source.
