I took this as a set with the EMG 81 with the non-soldering switch etc.. 1. PAIN to install, schematics are rubbish if you want to do a simple circuit like V-V-Tone with 2 pickups....I had to figure everything by myself and it took hours instead of minutes with a solder. 2. Thin, Spanky strat sound perfect for cleans, but underwhelming for neck leads when combined with the 81. Needs to get close to the strings to balance. Still Spanky. Considering the SA is considered the more meaty EMG single coil...It will take some trial and error to get the tones going. 3. During installation the pickup wires have the clip ends which are thicker than the cable itself. It the guitar has small drilled holes for wiring, you are in big trouble as you might end up needing re-drilling.
