I just purchased this bari. I had tested available horns in my area and some good and some not so. But the one thing they all had in common was a high price tag. Mysax teacher loves Ynai bari's. She and her husband happened to be taking a trip toLas Vegas and she agreed to test the solist for me. It is advertised as a computer copy of the B901. I must say it is. A dead ringer. She played a couple was so impressed she had Chuck Kessler record the serial # and put the horn on hold. She emailed my and stated, if you want a bari buy it. It is awesome. Being a 65yo student (awesome) doesn't always compute. She clarified that the low register wasvery good and the upper register was excellent. I called the following day and talked to Dave to complete the transaction. The horn arrived within a few days andPLAYED right out of the box. First time without going to the tech for post shipping adjustments. The Kessler experience, great. The price, at least half of local offerings. The horn. Sweet, fun, good looking, well made, AWESOME.
