Has anybody installed a master volume control in a 335 stlye guitar? My recently acquired Yamaha SA 2200 has linear taper pots which are driving nuts so instead of changing them I thought about installing an overall volume pot which would be an ideal solution. The both pickups on position yields some great tones on this guitar but they're largely wasted at the moment. I ride the volume pot constantly so it would make sense to have one on the pickguard and use a small black archtop style knob so it wouldn't look too out of place. If you've done this and can post photographs it would be greatly appreciated.
