I'm putting the 6 most influential hard rock rock guitar speakers in the same Marshall Stack to get the ultimate tone! :-)
The speakers are:
1971 Celestion G12H30 55Hz Greenback
1983 Celestion G12-65
1990 Celestion G12T-75
1989 Celestion V30 Marshall
1989 EVM 12L
197X JBL D120F
These speakers really complement each other and the combined tone is huge! The amp is 1977 Marshall Superbass modded into the #39 SIR studios mod (Appetite for destruction) and the guitar is a 1975 Gibson Flying V. I'm only using close mics here.
