On a separate but related note, there was an ampeg head and cab on fleabay about a yr ago. The seller had replaced all the internal speaker and main amp internal cable with heavier duty wire which he claimed improved the sound - his point being that it's all very well spending gadzillions on premium gear but the bits of wire inside the speaker and amp are typically cheapest thin bit of wire, so by replacing same with heavier duty stuff, vastly improved the sound. No idea if he was right as I din't buy the amp and cab he had for sale....but it seemed logical Captain!

I had a GK 200MB (that's the little combo, forerunner to the MB150) that I had to replace the driver on. When I opened it up, I was very surprised at the thinness of the wire going to the speaker. I think the outer sheath was no more than 1.5mm diameter, and that was for a 25cm or so cable run.
