Today I sent away for a set of 4 Hipshot HB6c-1/2 tuners. ($68 out the door!) I plan to use them for my 5 to 6 string conversion project for my SDAJV bass. It seems that I need to replace only 4 tuners (E,A,&G) to make room for the C string tuner. I think I can leave the B & D tuners in tact. The Hipshots have Fender-style clover keys, should look good. Is there anything to be gained by spending another 55-60 bucks more for only two more similar tuners purchased separately? What's the big deal about tuner weight? They don't seem that heavy to begin with!
