I'm in a bit of the same position. I put in my time as a full time keyboardist and at 52 I decided to learn bass just because I want to. My approach to choosing amps was very logical. A light head with plenty of power, lots of sound options and a headphone output should handle all my needs. Great for practice. Great for recording. Great for playing with friends. Got me a GK Neo 112 cabinet for carrying anywhere and a GB Uber Quad for being loud and clear. Got it all covered. Low volume through the 112 cabinet. Check. LOUD through the Uber Quad. Check. Home practice through the headphones. Check.
Reality check. I find myself using my Ampeg BA112 a LOT. It is dead simple. Plug in and play. No worries about molding my sound, connecting speakers and keeping up with pedals. Instead I focus on notes, timing and technique. I play along with the TV, the stereo and other musicians at practice with this amp and it does fine. I find myself practicing at home more because practicing through that little all in one amp is hassle free. I think, "I'll just plug in a play for 5 minutes" or "I think I'll go to the back porch a play a bit." These quick little sessions are always with the practice amp because I don't want to spend time connecting speakers or anything else. Those sessions also turn into 30 minutes or more of practice. IMHO, that makes my little practice amp the most important piece of equipment I have.
