Salud!
For those of you that have downsized from massive rigs, what path did you take? I'm looking for ideas for home studio/recording use, small venues and medium venues with PA support.
Sorry for the long answer, just to describe my path:
My first bass amp was a great 410 Hartke combo, but it was a real pain to move. I changed it for two of the TC Electronic "vertical" cabs, a 210 and 212 plus TC RH head, much easier to move. But soon I realized the 210 alone sounded just great for live use, as I just wanted to hear me clearly. I sold the 212.
I used that configuration quite a lot until I tried a MBass 12 cube, so easy to move. But then I started to use a 5 strings and it didn't sound so good with it, so I sold it and went back to my trusted (but somewhat heavy) 210. (later I went back to 4 strings exclusively).
A year ago I tried a superlight 112 from Lightbox (a company here in Spain) and it didn't sound so good as my 210 (too mid-ly), but it's very light (like 9 kilos, you can move it with one hand with no problem), just a fraction bigger than the MBass cubes and great for live use. My drummer LOVES that cab and has recommended it to other bass players.
I keep the TC 210, but don't think I'll ever need to use them both together, so I have the 210 for home practice and the 112 just for live use.
Regarding heads, I started with the TC RH450, had to sell it for financial reasons, then the MBass cube, then a EBS Reidmar head, it started failing, had it (badly) repaired, and, being unable to find a reliable technician and not trusting it anymore for live use, I got a MarkBass IV head, the one I use for everything. Great, simple, punchy, powerful, smallish. I have a GR mini just in case of need.
