Wow! Great topic Ironbar. I have always used Ampeg bass amps and have 4. BA112, BA210sp, B100R and Micro VR (with 2-2x10 cab.) The BA210sp is currently my favorite amp but that changes from time to time especially when I play any one particular amp for a few hours. To my aging ears the 210sp has more "thump". (moves more air) I have not played through many other makes of amp so I had no real basis of comparison.In the spirit of the other thread where people listed their worst amps, I'd now like to switch gears and have everyone list the BEST amp they ever played through. If this thread gets over 10 pages, I'll again tabulate the results and post them up.
I'm going to throw my own vote in there for a TC Electronic BG250 combo. I have no complaints about the thing years after buying it.
GO!
I recently picked up a Hartke HA2000 head and matching 4x10 Hartke cab with the aluminum coned speakers. (thank you again craigslist). I liked the fact that it has both a tube and solid state preamp. I was concerned when the tube preamp started distorting (more like "farting" for lack of a better term). I removed the stock Sovtek 12AX7 and replaced it with a JJ ECC83 S and that cured the problem.
I find the Hartke to be a totally different animal than the Ampeg (duh). It's a nice amp. The 4x10 cab is almost 100 lbs so I put wheels on it for ease of handling. This is not something I would haul to a gig due to its size and weight but in my studio it works well. It's loud and I rarely turn the volume up past 3.
Back to the topic... I would have to say that the Ampeg BA210sp is my favorite amp. The Hartke comes in a close 2nd. (in truth, I love them all)
I imagine that most who read this have multiple bass amps and enjoy comparing one to another. I know that there will be more amps in my future as well.
