Re: Greg's extended alto stick tuning
I had both tunings on my Alto. Extended is a full step higher of course, so if you don't think you'll miss that low b on the melody side give it a try. You won't need to mess with the setup much, maybe lower the c# string adjustment screw a half turn at the bridge, to accommodate for it being thinner than the b.
I prefer the standard alto tuning over extended, just enough low end on the b string to satisfy.
