Spring set up looks to be the the same as a La. handmade. Fingerboard comes off the same way from the inside reed side. I'm going to give Mike Gabbanelli a call in Houston and see if he can send me a set with lighter tension. Since he offers custom tuning I'm sure this will be an easy fix by just replacing the springs with a different set. Thanks for the input everyone.
On custom built boxes the ounces of pressure necessary to open the valves the buyer requires should be set when he picks up the accordion and subsequent adjustment should be made by the builder with either longer or shorter springs. Nail bending should not be done on quality accordions. It's too inaccurate.
