I have a 54 M-1, and I'd like to move over to gut strings, albeit with a steel wrapped E string (possibly the A too). My signal chain is as follows: David gage pickup, monster cable, Aguilar DB 680, QSC 850, 1 or 2 Aggie 112's. This amp rig combats the muddiness often associated with Kays (and the Gage for that matter). Basically, I set the frequency sweeps on the extreme highs and lows for each side, and It's fullrange upright nirvana! Also, the Kay has a rosewood board. I've poured over posts on strings, but I'm really only interested in real world experience from actual Kay users. Price isn't an issue, but quality is. Thanks for the help.
