It doesn't effect it. What you see is a strong pattern for the piano and some flickering background from the echo. It has a volume sensitivy circuit and picks the strongest source for its pattern. One thing it does do occasionaly, is if you have equally strong back and front waves like you get with a grand with its' lid up or an upright lid propped over the SAT the two waves will hit the microphone simultaneously and cancel each other out so you don't get a strong pattern. In that case, moving or rotating the SAT to point the mike in a different direction cures it. I've tuned several pianos in bars (pub to you) with all the rowdies talking at the tops of their voices and still gotten a fair to middlin' tuning done. I just stick foam ear plugs in and let them have at it. I tune each individual string in sequence, 1 to 88 and when I finish, I tell them to "pipe down so I can finish this thing" and go through quickly knocking in any thing that has wandered in about ten minutes. Most places will cool it that long. I've got several chuches with very good echoes, but the only problems I have are trying to tune the upper register unisons aurally like I normally do. I just switch over to the SAT and finish up. Hope this helps! Warren -- Warren D. Fisher fish@communique.net Registered Piano Technician Piano Technicians Guild New Orleans Chapter 701
