I got an idea I might try. If you like the highs on one amp and the lows on another, try cutting highs on the good lows and lows on the good highs and try to blend the mids. Sounds like a plan to me
A mate of mine said, try blending two completely different amps.
One that is dry and brittle with scooped mids, and one that is wet and saturated with some nice Midrange juice.
Smash the Mids out of the dry amp, focus the mids in the wet amp and fuck about with the presence controls etc, Ive found the Fryette 60M and the 5150 blend really well for my setup, massive bottom end and focused tight mids with lots of purr and saturated attack!
