Afternoon every one, last week I took receipt of my brand new TJ custom raw alto. It was like a dream seemed like a feather after my student Artemis. This week however I am experiencing great difficulty with F higher and lower, it seems as if the keys jam. I normally have no problem on the old Art. My teacher is on vacation at the moment and being a greenhorn ( been blowing four months) do not want to pester TJ with something, which someone on the forum has a quick answer to. Or indeed if someone has experienced a similar problem. Thanks in advance. Regds. N
