Hello friends. I'm in the process, due primarily to a hand injury, of changing from the traditional Uk upright piston valve tuba (Bb at the moment) to a rotary valve model. I am trialing a Meinel Weston Spezial 25 at the moment and can find absolutely no fault with it whatsoever. It is lightyears beyond the Soverign in terms of sound production, power, clarity, intonation etc It is also physically much easier to handle and fits well and naturaly into the human frame and posture (as opposed to the Soverign/Imperial which is a nightmare unless you're a giraffe with very long arms !). I just wonder if there are any tuba players out there (pro or otherwise) who have experience of this tuba (or one like it) with any views or opinions because I'm struggling to find any drawbacks at the moment and don't understand why all bands in the UK don't use them ? - they're sexy as hell too !!
