how can i get rid of some bass?

[mkstylee]

Hi all .
My jtm 45 reissue was comverted back to 65' specs by the previous owner and i was warned 'don't have the bass past 2 or it gets boomy' i believe the conversion included KT66 valves and all the mods from the raw sawage jtm/bluesbreaker site to bring it in line with a 65'
Well he was'nt wrong 2 is far too much .i know the originals were just a bassman clone of sorts and would be bassy but i would like to clean it up a bit i've ordered some higher gain pre valves to pust it a bit harder and would like any thoughts guys? Are stock jtm 45 with the 5881 valves bassy?

Have you tried all of your guitars? And also maybe some effects?
