I just picked up a used Modulus Quantum 6 today! This bass rules! The 35" scale makes the B tight as hell. The EMG's aren't my fave, but the bass still sounds awesome. My question to Modulus owners is what strings can I use? Most that I tried were too short. Also, how is Modulus with customer service? I'll keep you all posted on my thoughts of the bass. I'd love to hear about others who have these incredible basses.
