I am still waiting for the Rumble 1x15 cab to show up in store so I can physically eyeball it and try it with my 500 combo.
Could have used some extra power last night,as it was the first gig where my 500 combo finally struggled for volume.
I arrived thinking we were in a marque but instead we were in a converted chicken farm warehouse that was huge !! Could hear my bass fine to begin with, but in the last set the drummer and guitard got really loud and as they were having a great night I didn't have the heart to spoil their fun by telling them to peg it back a few notches.
But that is no black mark against the Rumble by any means (even my Genz rig would have struggled).
But on a real positive note I did manage to eq the Rumble well with lots of high mids and treble,very little gain,no buttons pushed, and when standing right in front of it the tone was amazing.
