OK, so here we go, Playtest impressions:
1) on the 'other' sax chat site, a poster I duly respect once noted that the intonation on these was quite poor. I am not certain what condition the horn was in in that instance, but here again my observations vastly differ.
The intonation up and down the registers is quite good, am talking a 10 cents or less variance on 80% of the notes, a few here and there slipping into a 15 cent variance. Basically, NO different whatsoever from what I have found with Conns, Bueschers, JK's, Kings, we can keep going. So the intonation is quite in-the-pocket.
2) an added bonus: she is mouthpiece friendly, unlike many a vintage Tenor. I used a variety of 'pieces...Meyer, Rubber Link, Brilhart Ebolin, Yama 4C, and lastly a Bari Esprit. The last one, a favorite budget model of mine which I actually put well in front of a 4C as far as sound and blowability....unfortunately oftentimes wreaks pure havoc on pre-1980's horns, so I never use it to test a horn I am finishing up; but in this instance it performed on this horn straight-and-true, as far as intonation goes.
3) Blowability: perfectly fine, good blowing response. Just a tad more resistance than, say, a vintage American horn such as a Martin, King, or Conn. The resistance isn't negligible, nor is it dramatic...if you get my drift.
3) Tone: quite nice, and actually here I would say that the few Youtube around don't quite do the sonic character of this model Tenor justice.
I compared her to two other vintage Tenors I currently have here: 1) an 40's Aristocrat and 2) an late 30's King Cleveland ...both with same-side bellkeys, FWIW. Both horns possessing a very nice, lush, full, vintage-y tone in their own right.
The Arta stood up to them, just fine. It is actually a bit wider-toned, possessing more spread, than the KIng or Boosh, which are more focused. More low-end overtones on the Arta...I would posit that if I had a vintage Conn here, it might be closer to that sorta sonic signature as Conns tend to blow a bit darker and wider than 'Crats or Cleves as well. Too bad I don't have a Conn or JK here for comparison now, as this baby is gonna get shipped out today.
I might in next few days add some other pics and commentary of various details /aspects as I think about it.
For the moment, this is the bulk of my assessment of this Arta Guban Luxor Solo.
A bit of an oddball, certainly...but a pleasant surprise, which in quality of build, tone, and performance is more than respectable and holds it own, really.
