Thanks Quetscher, we actually tried the Andes before the Hammond Soprano, but it always seam to sound slightly out of tune during playback, we could not figure out why. Some notes worked fine and some did not, we checked the Andes tuning with a chromatic tuner and we noticed that it fluctuated a bit with the amount of air pressure that was applied. This was especially noticeable on the lower notes more so than on the higher notes. I am thinking of buying one for myself just to see if this is normal for the Andes or if it was the player. It was brand new so he may not had enough time to practice with it and get used to playing it, (he was not the one on the soprano soloing). I actually like the sound of the Andes as it has a airy sound.
