Ovation sells their pickups online and although most players wouldn't want to route out their bridge for the OCP1-K iconic pickup, they may consider installing the SIX STRING THINLINE PICKUP 1/8" CREAM or SIX STRING THINLINE PICKUP 1/8" BLACK, each $37.99, as a drop-in pickup UST solution. This pickup comes mounted to a compensated saddle and given the name of the pickup and Ovation's proximity to Fishman, is likely made by Fishman. An impediment to considering this pickup may be adjusting its height for a particular guitar by likely having to sand the compensated top of the pickup to adjust its height. Then again, it may fit some guitars as is? Another possibility is that the compensated saddle upper part of the system is removable for sanding its bottom to the needed correct height?
