Thanks - I'm thinking of the Boss too, as I know how they work more than the Blackstar! It's a really interesting build: Fender Jazzmaster shape, P-bass pickups, simplified Les Paul wiring (one volume, one tone, one 3 way switch) and 9 gauge guitar strings (throw away the Es), and more frets than a standard uke. Low-G ukelele tuning. and sounds half-way between a ukelele and a guitar. Should be fun. And at least it can be played with headphones ?
