Aha, so this is now my fault? I was just trying to be helpful, honest :-)
I'm glad it's gone to a good home - it's been there for a little while, lurking at the end of the 'weird stinky poo' rack full of old Vox phantoms. It does look lovely in black - one thing Yamaha learnt from making all those concert grands is how to do a gloss black finish.
It took me a little while to get the hang of the pre-amp. It's capable of seemingly huge amounts of boost and cut on all 3 bands, and it seems to respond to dialling in small amounts gradually and seeing what effect it has. you can achieve huge tonal variation just by adjusting the pickup balance from one extreme to the other.
