Specifically I'm looking for a peavey classic 30 or an orange th 30.

Head or combo, I don't mind.

Looking to spend no more than £400.
I can get you a MG100HDFX that I just put on sale today. The price, if I see it as suitable, is completely your call.
^ That MG isn't even in the same league as either of those amps.

Stop trying to sell it in every thread you post in.
Main Rig:

Epiphone MKH Les Paul Custom 7 - Ronda
Ibanez RG8 "Scarlet" - AKA The Rambanez
Fender Strat "Danielle"/"Dani"
Line 6 POD HD Pro
Randall XL 4x12
