I used a Hipshot D tuner in the 80's and when I found myself leaving it in D most of the time I decided it was time to try a fiver. I bought a used Wahsburn in the late 80's and that was the end of plying 4's. Playing a 4 string feels like I have a finger missing. I'd rather give up the G string than the Low B string.

rumble monsters with little crispness and definition.
