Hi Don,
I admit to being somewhat fickle with gear, but I honestly don't buy with the intent to be disappointed. I try to research before I purchase, but sometimes a new product comes out and I just get itchy, so I jump on it without knowing all the story. I used my Digitech harmonizer for 10 years without a hitch. As much as I love the TC sound .... they have had their share of problems in the lower end for me. this VLT2 has been stellar so far, but I hardly take it out, since I befriended the PA900.
Good luck in your quest!
Dave
