Even though the newer ones have a higher turning ratio, in theory more accurate and quicker to tune, there was some unwanted slop. Now, the other difference of the Casino Coupe from my 339 Pro is the new unbranded Epiphone generic small-buttoned 'vintage' style tuners with the pressed in bushings as opposed to the 'Grover Deluxe' headstone or tulip-buttoned tuners with adjustable hex-bushings on my guitar. Wiggled it a couple times and got bridge sound back but remained crackly. When I attempted to switch from neck pup to bridge, no bridge sound at all.
The Epiphone toggle switch was either dirty or malfunctioning. The neck was consistent and frets were level and quite well polished. I notice this on mine as well, no biggie, it's a really fine player! The guitar's basic design and finish as seen in the 339 body size, is well executed from one to the next but leaves a little to be desired in the cutting, filing and sanding of the 'F' hole ends. Lots of usable, well balanced volume and tone.
The P90s sounded good, slightly percussive through the Fender Deluxe Reverb I was using. It played well despite it still needing a thorough setup. It's a generally good looking instrument in fit and finish. A Vintage Sunburst, an almost exact copy of my ES339 Pro, with the exception of the P90s, white pickguard, neck inlays and trapeze tailpiece. Well, just tried the newly arrived Casino Coupe at my music shop.
