Last summer I purchased a Lakland 55-02 from a fellow tber. I have been thrilled with this bass so far, but I feel it is now time to upgrade my amp since it is getting old and.. well not giving me the diverse sound i know my bass can give, My large amp is a Yamaha 1x15 combo. It's from the mid 80's I believe meaning large and heavy as well as having some degrading electronics and a not so clear sound. My practice amp is a Peavey Microbass which i find great for playing at low volumes any point in the day. Since I'm practicing with my bands more, and will probably be playing gigs in the near future, I want to upgrade my amp and as I said before, I'm looking mostly at an AG500 head and probably a GS212. I was looking for some recent feedback, as I've read lots of reviews from harmonycentral, TB's reviews, and some first impressions on this forum when the AG500 first came out. I would also like to hear any clips of the amp, mainly a comparison between the two channels, since that feature has made me lean more towards this amp. Thank you.
