hi i recently bought a h&k switchblade head that sounds great through the 4X12 in the shop,it was also h&k.but once i got it home and plugged it into my marshall 1922 cab its 2x12 with celestion gt75's in it it failed to deliver any crunch but it has really nice cleans.would i benefir from swapping the gt75's for greenbacks or v30's or am i waiting my time?

p.s a friend of mine who is a guitar builder reckons i should be able to get the sound i want out of the cab by swapping to green backs but im not so sure.
