Educate me please. I see a lot of people using a roller Tune O Matic bridge on Les Paul and SG type guitars. Guitars without tremolo systems. What for? What's the advantage? I can see if you have a Bigsby, but I don't see the reasoning for non-trem guitars. I would think the smaller the contact point with the string, the better. So in that case, a standard TOM bridge would create less contact with the string, right? I need to replace the TOM on my latest purchase (Jay Turser LP copy), so I'm just wondering if it's worth getting a roller bridge.
