Having been inspired and tempted to start a mouthpiece safari, I did check around and there really is no shops/schools open for the foreseeable in Ireland
Rather than the full safari, I decided on something more like a day trip to Longleat ... and am now the proud owner of a 1 1/2C, 5C, 7C and 10C mouthpieces - and there is a lot of variation.
Its still a starnge feeling the 10C feels lose, but the sounds are richer. The 1 1/2 is harder to push the air through, but it is kindof quieter - but D5 is tricky at the moment with it.
Still all in all great fun.
And for fun I followed Mr Walton on a cheap and cheerful Wah-Wah - i have nailed the growl once or twice - now have it in my warm up.
