Audiogabby,
I take it that you mean that you're pairing it with the Eastern Electric Minimax PREAMP, not amp?
I've never heard the Minimax, but if it's like a lot of tube preamps, then it may be a little soft in the bass. Don't neglect the importance of the preamp in the overall bass response. You might find that you won't have the deep bass that you want until you find an amp/preamp combo that can achieve it.
