I had a 5000 for years and much prefer it to the 9000. Looking back I have no idea if I had a specific version. It’s a really simple pedal relative to the 9000 (and lots of other higher end pedals) - which lends itself to being really durable. And also, you play to it versus having a million minor ways to adjust it, if that makes sense. I play a Yamaha FP9 now and, while it’s an incredible pedal, it’s so adjustable that it’s almost like you can lose what it’s naturally supposed to feel like. Again don’t know if that makes sense. And I bet if I played them side by side, I bet I have my Yamaha dialed in to feel probably just like the 5000 since that’s what I played for so long. It’s like someone investing thousands of dollars on every bell and whistle in a crazy light and fancy bike but then finding himself wishing he could just ride his old Mongoose BMXer every once in a while. Anyway, enough rambling. Great pedal. Go rock it.
