OK, well this little thing works well...but I was not expecting it to make so much noise! The first time I recorded someone who was using it, the sound of the Body Beat Pulse Solo could be clearly heard at the end of the song where the last strummed chord of the guitar decays. It's not only annoying, but there's no way to fix that in the recording! I tried repositioning it against the back of the guitarist (a position farther from the microphone), but you could still hear the Pulse in the recording. Frustrating, because I REALLY LIKE what the Body Beat does.
