I couldn't find any I, Q, U or X manufacturers whose bases I liked.
So I cheated with the (Switch) Innovo, (Riverhead) Unicorn.
I could have also had the (Vaccaro) X-Ray but I didn't think it was different enough in looks - it's essentially a pointy P-J bass with a semi-aluminium neck.
And the (Knuckle) Quake but again it's very ordinary looking apart from the 39" scale length.
