This arrived with Thomann's normal efficiency. The flimsy cover was cracked in two places, rather than send it back I took photos and asked for a new cover, which Thomann have agreed to send when they get one, which to date has not arrived after 3 weeks. I especially like the default to channel two. The method of changing which midi channel it is sending on is simple, and can be done easily with the feet. I have played with the Octave shift, but I can't really thik this would be of any use to me they are Bass pedals after all. There is a sustain option but after playing with it out of curiosity, have not bothered. The metal frame promises to help the item have a long life, with all our equipment we treat them well rather than just fling it about so I am not expecting any problems. With the three year guarantee as well what is there not to like? Plug and play simplicity is what is needed and this is what we got. The price seems fine. What is missing? I would like the option to be able to turn the velocity sensitivity off, rather than doing it in the midi box but this is a minor point. We got what we were looking for and the switch mode power supply is fine. No discernable noise injected into our PA caused by this unit. 4 stars only due to the flimsy cover though.
