I have a Zoom B9.1ut for sale that is in excellent condition. It has seen little use and if I don't need it then it has to go. I think it has a few scratches on the bottom but besides that everything works and is spotless. I think I only hooked it up once to try the USB interface but that was when I first got it. I know Zoom discontinued it but I thought this was one of their best pedals ever designed. Tons of options tonally and the tube in here did make a difference to me. I am the only owner and it has been babied. Looking for [DEL]$170 shipped[/DEL] OBO. Now $155 OBO shipped. The plastic is still on the screen!!
