In 72 due to complaints from guitar player a circuit change was put in place on the 250 and 150 amps to provide more gain.

This worked great for the guitar player, but I find that for bass I like the pre 72 non mod better , there more dynamic range for bass use and as such less chance of driving the amp into clipping

If you have one of these amps it's all of 5 bucks worth of parts to put it back to it original production form.

Another thing that helps when you have a active bass with hot output is to run the volume on the bass down to 3/4s or less and turn the amp up more.
