Its funny I'm a 'worse than' or 'better than' depending on which instrument I'm playing and where I am.
Took up the fiddle recently and now I'm definitely a worse than.
At sessions at festivals I'm a 'worse than' on melodeon/concertina, but at local session at the slow one I'm 'better than' but fast one 'worse than'.
....and on fiddle definitely 'worse than' everywhere. lol!
Even got a sign of relief last time I put down the fiddle I'd been 'playing' at a session and picked up the melodeon.
Ooops!
