This accessory is a must for the operation of my TBX150H. In my opinion, it should have been included with the amp. Ibanez geared the amp and switch to be a working man's outfit and keep the componants affordable. I have had this outfit for about a year. I don't know about the longevity of it, but the results in performance are undeniable. Nothing short of excellent. The only complaint I have is the length of the cable, not too bad and easily remedied. All-in-all exactly what you'd expect from a footswitch.
