My latest acquisition! A Czarcie Kopyto double bass drum pedal. Looking at the pedal, there are a lot of similarities with the Trick Pro-1V Bigfoot I already own. For example, you can change the pedal setting for more power or more speed or an in between setting. Also, you can move the drum clamp backwards and forwards on both. The connecting rod for the double bass is "inspired" by the Trick as are the beaters. But there are also a lot of differences. The Bigfoot footboard is about an inch longer but the Czarcie is wider. The clamping system on the Czarcie Kopyto is a spring loaded screw on type and it also has the ability to change the throw of the beater. Also, while the Trick is a compression spring pedal, the Czarcie is a traditional expansion spring design. The Trick method for changing tension is excellent, but the Czarcie's is kind of cool too. Set and forget. Playing wise, there's even more difference. Whereas the Trick is a pedal with a light feel, the Czarcie has a very heavy feel to it. Nothing to do with speed, just the feel: I think the expansion vs compression spring modus operandi adds to the difference. I'm really digging it! A really great pedal, I think it's a better feel for me than the Tricks, which always used to get away from under me. I always preferred ICs to the Pearl Eliminator, this is something in that vein.
