Over the next 2 months our band will be purchasing several pieces of gear and I'm looking at some bass heads. Seeing as I don't know what size venues we'll be playing, I need a head with lots of headroom and I want something light. More importantly, however, is the issue of reliability. Living in Grand Cayman means that if something breaks down, repairs will not be possible without expensive shipping to the US. Also, I'd prefer solid state over tube (although a single-tube pre-amp is fine). My current considerations ar: GK 1001RB (good power, light, but reliability is a concern), Peavey FireBass 700 II (good power, reliable, but heavy as hell), and a Mesa Walkabout (lower power, light, expensive, more than 1 tube). Anyone have any other ideas?
