I found this one out pretty quickly. I have an Ashdown ABM combo amp, and the blue speakers tend on the mellow/indistinct/lacking clarity side when you're just doing the 'thump thump' thing, but after a short while of not being able to hear
anything I was playing over drums or guitar and getting really frustrated at their unwillingness to sacrifice "their" sounds and volumes for the good of the band, I disconnected the tweeter, pumped the treble and raised the lower mids slightly, lowered my bass's action and started 'tapping' the strings against the frets with my fingertips to produce a percussive clack ala John Entwistle (no, I'm not suggesting I'm at his level of playing, thank you.)
Anyway, got the deer-in-headlights look at first, but all it took for them to quicky get over it was for me to explain that this was "my" new sound and that I'd only mellow it out if they did the same for "their" sounds. Needless to say, thanks in large part to their stubbornness, you hear can most definitely hear what I'm playing on the bass.
