First post . I just bought an SX Ursa4 RN 3TS (Rondo took the product listing down recently) that's coming in monday. Looks like a jaguar, 34" scale, seems like a decent first bass. I've played guitar for 8 years and I generally adjust action by feel, since I know what sounds right on a guitar. However, since I haven't "bassed" before, I decided to use my 64th inch increment ruler to be more precise. Now, I opted to not buy a radius gauge, as in my opinion, measuring string by string should form to the actual radius of the fretboard. Also I don't like giving Stewmac money. The specs I'll be using are 6/64th's on the bass side, 5/64th's on treble as a baseline. My question is this: Does bass side = bottom two strings and treble = top two? I'm 98% sure it does, especially since the top two strings are past the apex of the radius, but I like to be thorough! Thanks guys! I'll write a review when I receive the bass, I bought a used Fender Rumble 100 to go with it - so I'll review that too . Have a good Friday! I talk too much.
