I know there was a recent thread about BBb Bass mouthpieces but it is more advice that I need (I think) rather than a technical discussion about mouthpieces. Basically, I have just moved from Eb to Bb (something I have done before but this will be a permanent, or a tleast long term move). I am struggling with the DW1L mouthpice that comes with the instrument I have inherited, when I moved before I simply carried on using the 3L I had for my Eb and this worked well, but, and this is the crux of the matter, is this good long-term idea or should I really be persevering with the 1L? We're only 4th section so it isn't as if I will need any REALLY low, register wise. ANY advice would be gratefully recieved!
