Anyone notice a change in tone when playing with a generator? I recently used one with a small SS practice amp and Tele and it sounded very different than usual(220V wall), loud with a higher resolution, more open, but also more fat and gnarly, if that makes any sense... I really would have liked the tone if not for the hum and noiselevel which seemed overemphasized as well. Is this indicative of a wiring problem somewhere, or do I need some sort of power conditioner? Any general recommendation, pitfalls and advice guys?

Assuming that it is a petrol generator, I have one that advises that it be earthed to a
metal spike in the ground. The hum could indicate an earthing problem. arf

Tnx Arfer, yes petrol generator. I don't think the generator itself is grounded, it is however connected to the mains of the house. (In case of powerfailure, we fire up the generator and simply pull a handle that arranges to pull the juice from the generator instead of the powergrid) Is it safe to assume it's automaticly grounded this way?

My gen instructions definitely advise to earth it, which I always do when working outside. I have never used it for indoor purposes. There are many electrical experts on this forum. Perhaps the have the anwer I'll have a wnader round the electric forums. Arf

JUst been thinking Ric, my gen is a small 750 watt type. Yours sounds like it may be a quite big one. Arf

I think it's 1200W Arf. You figure it would make a difference as to the noise and humlevels I'm experiencing?

Just my thoughts but it could be a grounding issue. I'm not a tech but I did take some electronics classes way back. I remember testing a device with an oscilloscope that had the ground prong on the 3 prong plug broken off and it gave some wild signals on the screen due to it not being grounded properly. This could result in "noise". I think I would search the manual or contact the manufacturer or the seller to see if anyone else has had this issue. You may find an answer there. Hope this helps.
