A nice Eastman ( single neck pickup type ) Archtop would get my vote; perhaps a nice 803, 805 or 905 , with a B.K.P Manhattan / rewind in the neck e.t.c
However
I can safely say that ( believe it or not folks ) my upgraded 'Vintage' VS575 + Bkp Manhattans has long continued to keep me very happy. I do have in reserve , my Ibanez AF75 with B.K.P. AII Stormy Mondays - for a nice contrast / back up, if ever needed . As a result, the above mentioned Eastmans would just be 'Guitar Porn' for me - as opposed to making me actually want / need to buy anything more. The eventual realisation dawned , that what I really needed and now greatly enjoy, is " Time on the instrument" - not more instruments.
In fairness, I did have my last 'gasp' of G.A.S compiling a 'dream' amp head / cab rig this last year - and a consolidating a couple of nice compact 'carry on the bus, in a padded shoulder bag ' surrogates.
It is now my ambition to become a musician ... :lol:
