I owned a GA15 - black/USA-built. Solid amp. Not a whole lot of clean headroom with the 15-watter. I always wanted to try the GA30, but haven't seen one in person....and they're a little pricey to just take a chance on. I used to run my GA15 with my Deluxe Reverb and it was a nice, little setup. It's in the Vox tone camp, but it's got it's own thing. And it's a good thing. I never had any issues with mine. It was load to carry, but it's more compact than the GA30, so that made it easier. But I have a Vox AC15, now. Makes the Gibson seem almost light. I recently traded my GA15 in on a new guitar, but it served me well for a few years. I would think the GA30 is a very cool amp - likely very heavy as well. But sometimes that's an OK trade-off (for example, my AC15 ). FWIW, I paid $450 for my GA15 when I bought it. It was used, but it in very good condition. It was easily worth what I paid for it. $1800 for a GA30 seems pretty high. Whenever I seem them listed, though, they all seem to have pretty steep asking prices.
