Been fancying a dabble with a fan-fret so just ordered up a Dingwall NG2, 4 string in Lamborgini Orange! Will let you know how i get on with it. Mind you, when I had my bass business we had a couple come in and I found them quite intuitive to play.
Nah. I'll probably end up dabbling for myself one day when I've got disposable income once more. I like the idea of the extra long E. It'll be interesting to see if it's anything like I visualise.
