Loop Master contacted me. My TC Electronic's Chorus has a built-in preamp and the gain was set too high. I just got it last week, so I have not messed with it much. I reduced the gain and the problem is solved. I knew that it was not the looper, I just couldn't figure it out. It was popping so loud, I thought it would blow my speakers. Anyway, I would suggest buying Loop Master products. They make some really high quality, heavy duty, products.
