Bang on... your tone is something that you develop--and will continue to develop--for as long as you play the bass. That said, for my money the best all-round amps are Ampegs. If you can afford a B-series head you'll get all of the power and versaltility that you'll probably ever need, regardless of the size of stage that you're playing on. I own one; it's married to an Ampeg 410-HLF cabinet. It sounds great with either my Modulus or my Precision. Articulate, beefy, dynamic, punchy... and if I want, as loud as hell. I also agree with setting some coin aside to purchase a top-notch mic and DI box. You'd be amazed at the number of clubs where the sound guy only gives you a piece of crap DI to plug into. If you spend time and money caring what your sound is like, make sure that the people that come and see you will get to hear it, too. Get an industry-standard SM-57 and a Countryman DI box... and if the sound guy has the imputs available on his board, insist that he devotes two channels to you and run them both.
