A few years back, however, he blew one of his bass cabs (a Gallien-Krueger NEO410/4). Well, he just blew another cab using the same head (not sure which cab this one was).
Either way, I talked him into buying a Helix a few years back, and he's neglected to use or learn it because it's overwhelming for him.
Well, now that he's blown a second cab,
He plays predominately hard rock, with a little metal here and there, and will be playing local bars/clubs, generally with no PA support for the bass, so whatever he uses will have to be able to stand up to being loud enough to fill a decent sized bar without falling apart.
I may try to have him take the amp in to be looked at, as you said, just in case. Though, at 500W, perhaps it might be worth him getting something beefier anyway?
Truthfully, he's not the tone monger that I am, so I imagine how he sets his EQ depends on his mood.
Unfortunately, during our recent audition, his cab was farting on occasion. Not all the time, but definitely enough to be noticed, and more frequently as the day went on.
Something worthy of note, playing at a place with 1,000+ people is kind of a dream in our case. Reality is, throughout the year the places we play will probably have a maximum occupancy of 300 people, give or take.
what I've taken from this is that it would be a good safety measure to HPF 50hz or so, in an effort to protect the life of the cab. Do I have all of that correct so far?
