KT88s are generally more reputed to provide rock-type bass and drive than EL34s, but of course other factors in the amp come into play as well, notably the output transformers.
I've been trying to get good bass--weighty, defined, fast, extended--from tube amps for a while. I've found an amp's bass can be improved with a bit of work. Speaker placement and room acoustics count for a lot. Other useful measures include getting the amp down on the floor or near it, on a good platform or stand.
