I had been playing bass for a while, started off with a beginner bass amp. That lasted for about 2 years and I gave it away to a friend. Decided to upgrade to something more worthwhile. Mesa Boogie Subway TT-800. Needed a cab to start with, decided on the subway 210 and subway 15. Eventually added another 15 and a 12. Well damn, this rig just shakes the house to no end. You know how it goes, new amp leads to other things like better bass guitars.
