Well, since this thread popped back into life I'll continue. I did change the Snuffy Smith head and put on a 5-star head. After some adjusting of the Moon bridge, and taking the Kirschner tailpiece down as close to the head as possible -- making the angle of the strings from bridge to tailpiece about 14 degrees -- I'm finally happy with the tone I'm getting. It's bright and snappy without being too brassy. Putting on a new set of strings always helps, too.
