I owned a Skyline 55-01 briefly. First off, a well made bass! Nice and light. Now for my dislikes...............
19mm string spacing (too wide for me)
35: scale (I'm a 34" scale guy)
Pre-amp (way too harsh and zero character, IMO)
Mandolin size frets (I'm a medium jumbo, jumbo kinda guy)
Passive/Active switch (Not a true passive/active, if the battery dies, you're dead in the water)
Having said that, I'd still like to test out a DJ model and a 55-94 model!
