First off, I did a big search through all the available loopers, having owned several in the past. I do a lot of live looping accompanying jazz singers where I need long loop times, great sound quality and easy operation. No effects or overdubs, I either don't need it or have other pedals available. So my one complaint is the silent erase. After a song finishes and the loop is off, there is no easy way to silently erase the loop. What you have to do is hold down the relatively flimsy volume button for multiple seconds until the left button starts blinking, which you then have to press. That is a lot of time and effort! This can be ameliorated somewhat by buying an extra fx switch but you will still have to hold it I think. Anyway, great looper, almost perfect for me.
