To make it short: I use this pedal for 6 months and am very satisfied. Currently it is connected to a Yamaha P-155 and thanks to the changeover switch on the bottom you have not only a nuisance to the electric piano reprogram (for the polarity) and is therefore on all keyboards with normal Sustainanschluss (6.3mm) anschliesbar. Solidly built, non-slip and lightweight rubber smell is gone after 2 weeks. This very high quality pedals playing is fun, strong buy recommendation!
