I think its very different then modern pedals. I own a vintage speed king and love it. Modern pedals are all about going as fast as you can. The speed king is for more control I feel. It sticks to your foot better(cause of the twin springs), is smoother then any pedal i feel, and the control lets you do intercit patterns. If you buy one, it doesn't matter what pedal you've been playing, a SK is a whole different feel. So if you find one at a shop or such, play it for a good 1/2hr or more so you can really get used to it, and then determine when your used to it if it fits your needs. The quality is second to none, and the pedals are designed so you can replace anywith with basic home tools. Not little custom made gagdets that cost a lot and only work for 1 pedal. I like a foot board to really stick to my feet, so if your like me and have the springs tightened up high to get control, then a SK would be a good choice. Instead of having 1 spring tighten up tight(creating drag, and friction, slowing your performance), have 2(like in the SK) tightened up 1/2 of what you did with the other pedal. So the pedal with still be smoother, and stick to your foot.
