When I got my Upton Hybrid last fall it was strung with Spiro Mittels on their recommendation. The bass just sounded great to me and others who played it, but I had a Weich set on my other bass and they just FELT better to me so I swapped them. Night and day difference in playability.
However, as most everything in life is a tradeoff, I gave up some volume and tone.
The Obligatos will either do the trick or maybe I'll try the SF or Corelli's or or or or or or or ??
Screw it, I'm going to practice.
