... And thinking about it, guitarists never seem to moan about carrying a whacking great Marshall valve amp around, so a 13kg bass amp isn`t that big a deal to me.

I'm a guitarist too, and believe me, amp weight is an issue! I never went down the stack or half-stack route, but I have long since ditched arm-lengthening 2x12 combos in favour of much lighter 1x12 models. Even so, my main gigging amp is by far the heaviest piece of kit that I own.
