i watched a bunch of videos. i have a TC x4 delay and looper but i dont care for the look and interface of the TC harmonizer. i am actually going to to with the boss. it seems easier to use and what not. i am pretty sure once youre live people wouldnt be able to specifically tell the difference between the TC and boss. problem being were only watching videos of them running directly into the feed. and dont forget. we can always return the pedal if we dont like it
