I also (re) disovered that 'Piano' tone with my Mississipi Queens in a cheap / quite heavy 335 copy earlier today , and light GeorgeL's strings ( 10,12,15,24,32,42 ) . Sometimes, It really is about finding that ( often unexpected) combination of random components - and an amp clear enough to reveal them. My amp was the diminutive and much used / loved Roland Micro-Cube, on JC120 model. Lovely tones. :)
