My bass teacher had a Glockenklang Bass Art head with a matching 4x10. However, my second amp ever was an Eden 4x10 with a Navigator through a Stewart solid state. Not too shabby, and a good upgrade from a 30watt fender combo. And then there's my current amp, which I'm quite happy with. Schroeder full stack, 1800watts, QSC amp, and, oddly, no preamp, just a DBX 160a I feed directly off my pedal board (so you could say my preamp is a Sansamp BDDI pedal). Hard to pick just one. They all sound fairly different. The Glockenklang just felt really elite and cool though. Didnt get much time with it though.
