I'm assuming the OP means fluorescent lights rather than neon.

Also, anything on a simple thyristor/triac control will cause some noise as at settings lower than 100% it will switch on when the ac waveform is part way through its positive or negative cycle.

I walked up and unplugged a neon bar sign that was directly behind the amps ( and sharing power) and everything immediately cleared up.

Things like that are always good.  One of my friends would comment "Now it's your turn to wear the smug hat".

Nope - neon. http://www.jantecneon.com/Neon-Sculptures.html  Ubiquitous in bars in the states, but slowly being replaced by LED.  I would say we only have about 40 years to go in the transition.

O.K. I stand corrected!

I made the assumption because I have lost count of the number of times I have heard fluorescent lights referred to as neon.

Over here it's very common to see neon lighting externally but I haven't seen much inside a building.  When I have, it has usually been in a US themed diner!

No, the OP was asking about neon and sound system issues. Everybody jumped over to guitars.
