I also have early purple logo alto, I'm just wondering if this neck on eBay is genuine stuff and does it really improves on original one. I did try custom necks, G1, V1 on my alto and was not satisfied with the results.
Hmm, it's unclear what this is. Here are the current necks that Yamaha sells in the US:
I have a Purple label YAS62 and 2 extra Yamaha necks - an unlacquered G1 and a silver-plated V1.
The G1 and the V1 both have gold Yamaha logo "disc" with no paint on them, so it's unlikely one of those. The new YAS62 III photos also have this gold logo disc, so it's not a "62-style hydroformed neck"...
I picked up these aftermarket necks in the past 5 years - I wish I had gotten them long ago - I'd probably be more of an alto player and Yamaha fan.
The G1 and V1 to me have a lot of the same strengths and overall sound. (I haven't used the UL G1 too much in recent years - I don't play that often and when I do I generally reach for the V1)
* altissimo on the G1/V1 play easier for me and I'm able to maintain the notes. I struggled with altissimo in college with the stock neck (I had no problems on my Mark VI tenor, tho!).
* there's a world of difference from the perspective of the player. Maybe these necks give me the feedback I'm looking for - it sounds better to "me". Oddly, in recordings, the sound is pretty similar - perhaps the only difference is that you can sense I'm enjoying myself a little more, perhaps a little more "pep" to my playing with the V1 than the stock.
I would say that I had my YAS62 for about 3 years before I got the MK VI tenor, and while it played smooth, quick response, my Mark VI always felt more satisfying to me, that is until I got the G1/V1.
I got my UL from PM Woodwind. They have a lot of used necks at any given time. I snagged my V1 off eBay.
