I bought one of these a couple of weeks ago and I really like it, alot of features for very little $$$. I bought one after reading positive reviews on it gathered from this site and the Harmony Central amp database, My question is this. My amp's Bass control doesn't seem to add a significant amount of bass. The amp is way punchy but I want a bit more bottom end and growl.The ultrabass feature adds some bass but sounds more like some kind of echo effect and doesn't seem to track quite like it should, so have any of you expearinced this or is there something wrong with the one I have? When you use your Bass control does it add alot of beefy bass? Mine doesn't add as much as I would like. Since I have only had it a couple of weeks and I bought it from Musician's friend I can return it and exchange it. I guess I just want to know if any of you have experienced the same thing or feel the same way about the bottom end tone of the amp.
