I'm just wondering if I'm the only one using these mpc's. I don't see a lot of post or in the real world hear or see them anywhere. I've been using the graftonite on both my tenor and alto with good results. I bought all three chamber sizes (A5, B5, and C5) for 45 dollars. Uses: A5 background; B5 intimate settings, weddings, etc; C5 for live club & festival gigs. I think I have a good ground for comparison. I also have OttoLink STM, OttoLink Tone Edge, Brilhart Level Air, Brilhart Tonalin, Hite Premier, and Vandoran Java. All good mpc's (Tonalin very good). Just wondering.
