I bought the BA-2 based on reviews I'd read on various bass forums. At first blush, I was DECIDEDLY UNDERWELMED! "This is it?! Huh..." After all the great words it simply didn't hit me in the face with some spectacular, orgasmic sound. That was short lived. I'm embarrassed to say, I did not recognize this for what it is... a sleeper. The second time I sat down with the BA-2 was to play bass, not to play with a new toy. I plugged in and it sounded pretty good, immediately. I'm a studio owner and play any instrument in many genres whenever needed so I started playing thru style after style. With every change I could immediately dial up what I wanted to hear and each time, with my custom built studio bass (no one touches but me) or my modded SR500 (for gigs and clients to use), it made my instruments sound really good. More importantly, played with recordings, it always fit PERFECTLY! This thing is SO much more impressive in the mix than sitting by yourself noodling around! It was just fun too. The distortion the BA-2 has, I thought, might sound interesting on acoustic guitar. So, I plugged it in... SWEET! Somehow, with judicious use of the distortion section, it makes a piezo pickup sound more like a "real" acoustic guitar. An acoustic singer/songwriter buddy of mine traded me his modded Tube King, a TS-9 and L.R. Baggs DI for the BA-2 upon first listen. So, the next day, back for another BA-2. Last one in stock. Whew! Then, when my studio partner realized I was planning on taking it with me on an upcoming trip he says, "You can't take THAT! What will I do while you're gone?" So I ordered another! The BA-2 is now the first thing we grab when we want to apply distortion to any instrument except electric guitar! The distortion is consistent whether you hit it hard or not so it does not break up more with more input like a tube pre. No flash. Nothing screaming "Look at me! Look what I can do!" It just sits there... sounding awesome!
