I'd have to admit to being as 'glass-backed' as they come, and even older than that (dunno about the 'geezer' bit, but still...); I'd still be highly interested in this ensemble, but for 1 - already having several valve amps, 2 - not having any spare cash at all for now, 3 - living on a different part of our common tectonic plate and 4 - being a drummer (..!).
I'd echo the surprise above about this not having been snapped up; this amp has not 1, not 2, not 4, but 8 (yes, eight..!) KT88 valves, which are without question, the valves for a bass amp. I have a Hiwatt DR205 (200w PA head...) for bass, which has four of these valves, and is clean up to the heavens, even at stadium/festival volumes; this Nexus has more potential (is that even possibles..?), plus the full set of bass-purpose controls to dial in grit if needed, and all mod cons for going to FOH or recording console. The pricing is keen; very keen. If it's still here when I get my lottery win (which I doubt; I've yet to buy a ticket...), I'll be over in a jiffy with my estate car to load it up (I'd need some help with that, of course, being even older than that, and glass-backed...).
Meanwhile, have a bump, and good luck with the sale.
