As it understand it, EHX pedals – like those you mentioned, don’t like to be daisy-chained. If you do an experiment; take all the pedals off the board, and plug each individual unit into it’s own power supply on a power strip… Or surge protector… See if they still make that whiney hiss. Once you’ve determined that to be the issue, to continue to power each EHX pedal independantly, get a 1Spot power supply with the multi-connector cable. About $39.95 if I’m correct…
I have a Voodoo Lab PP2+, but have both 250mA AC outs in-use by a DD-20 and an EHX Micro Pog… Is it possible to use one of the standard 100mA Boss-type outs on the PP2+ to power the Holy Grail +???
Or, can I use one of the PP2+’s 250mA outs and daisy-chain the Micro Pog and HG+ together?
Any help would be great…
