Congratulations on your new accordion! I spoke privately with you a while back, and think you made a wise choice buying at Liberty Bellows, especially as it's your first accordion, and LB really offers a lot of choice. I found them to be very patient as I "shopped" and decided. As a matter of fact, last week I too just drove up to Philly, bribed my wife with a meal, and spent the night.
My year long experiment playing Chromatic Button Accordion just ended, and I took two CBA's to LB. (I previously bought one from them, and another off EBay). Mike accepted two for a very slightly used Beltuna which I really like. As you journey along, perhaps you'll follow me with my collection-- a 120 bass (ladies size), a 96 bass, and my new 72 bass.
Best wishes, Joe
