I Invested in Boogie heads and 2x15s in 1988 and haven't wanted any other amps since. My amps and cabs have changed but only for lighter Boogie gear making the same sound.
Bass-wise, I'm a dyed in the wool Precision player and have only bought other Pbasses so I don't have to take the old Fenders out on the road.
I'm the epitome of dull (and should be a Boogie endorsee by rights!!!).
