So i know this is probably a long shot with all you guys using boutique amps and what not but have any of you got a classic 30 and modded it? I've been reading up on the "blue guitar" mods as they seem to get called. I'm specifically thinking of changing the speaker over first. Possible a Celestion Heritage G12M or a Celestion Gold but the gold is twice the price of the g12m Basically has any one modded their classic 30 and how successful was it and what does it sound like compared to how it did as standard? Steven.
