Only very long power cords can give a problem, over maybe 90 feet, but that loss is dependent on the load, so no worries there. I would not expect that a surge protector will cause any trouble. Why the question do you have issues?
Alan.
I have like 5 different things plugged into a surge protector, and I was reading about guitar amps today and came across something that mentioned and amp might not get the full power if it's plugged in with a lot of other gear. I was just wondering b/c of that really.
Thanks Alan
Maybe if it was in a live gig situation there may be a power loss if the light show, PA and guitar amp were plugged into 1 outlet, but in the studio? No I don't think you will have any issues. If you are concerned bypass the surge protector with the guitar amp, it would have to be one hell of a surge to blow up a guitar amp.
For the record my band did a house concert last Saturday, we had 4 x 300watt par cans, a 200watt a side PA, a bass amp and a guitar amp and we had 1 power outlet. Now it was a quiet gig but there was no power loss and no hot power leads LOL. Note for the tech types, this was 240 volts as I am in OZ (actually in west OZ it's usually about 254 Volts ), so the amps is different from the 120 volt US stuff, but it's all relevant.
Remember when the load is shown on the back of gear it relates to the load at full power, so if the guitar amp is running half volume the load is less.
Alan.
I only have a UPS/power filter on the recorders and computers, amps just get plugged into the wall, to be honest there would have to be a lot wrong to upset a guitar amp.
Alan.
For the record (and just to be pedantic), voltage and current are two different things. Current is measured in amperes (amps) which is why the label on the back of your gear will likely say something like "3 amps at 120 volts".
(actually in west OZ it's usually about 254 Volts ).
Damn Western Australians.... just have to do things differently, don't ya?
