Ross Nicol from Abbey Sound is a New Zealander!
I guess that had a lot to do with him having his business way out in the sticks at Seaford. (Not too far from the sheep, heh, heh.)

Ross builds and sells and hires P.A. systems, and repairs them and guitar amps too.
Ross at one stage manufactured very high quality guitar amps and if you see one second hand in your travels, snap it up!

He can also often be found manning a mixing desk at live gigs.

His web site has a section titled "Abbey School".
There is some excellent information there about (valve) guitar amps, P.A. systems, and a glossary on mixing.

I have found Ross to be always cheerful and ready to go out of his way to help and to offer good advice.

He also has a life outside music, hence the picture.... Perhaps another reason his factory is in Seaford is he's only about 300 metres from VicRoads!
I hope he doesn't mind me posting the pic here!
