Ok, so I've just about talked myself into buying a ZKT 1500. I tried it out at the ITG, and fell in love. After a while, the guy working the booth handed me a 1500TW. While I really didn't like the brighter sound, the concept of having a rounded tuning slide as a "just in case" type thing was enticing. Can anyone tell me if you can purchase the rounded tuning slide? I am planning on purchasing the horn from Pick Music (provided they still have one) and figure that getting the slide at the same time would make the most sense, if it was possible. I'd call and ask, but I work most of the day, and figured this would be just as simple.
