Hello all, In over a year that I have had my Icom 756 Pro II, I always meant to ask this question. Is there an audio tone adjustment for this radio. I know where and what everything else does, but it would be nice if it had a way to roll off the bass end and also accentuate the high end when necessary. Thanks for any help, 73, es g.b. all. Kind regards, Marty, W3QK
