A big and beautiful 1939 L-7 archtop on the bench for a bunch of repairs.  You can see some of the work done here.  These repairs include new frets, new relic Waverly tuners, back binding repairs, side cracks and a K&K Devinity system pickup installation.  I must say that I'm not normally impressed with acoustic pickups but this newer K&K pickup sounds very warm and transparent.  I installed one of the older K&K archtop pickups in a 1940's Epiphone Emperor years ago and found it sounded very hollow and out of phase (even with correcting the phase with a preamp).  Archtops can be difficult to amplify acoustically.  After hearing this pickup I recommend that you give the K&K Devinity a try.
