That'd be the bass of my dreams.
According to the website and confirmed with a phone call with Rob last year, the standard Mouse with Maple top build is a Mahogany body and Goncalo Aves fingerboard.
I personally am struggling between a Maple Mouse with F hole or a Deep 4. Of course money is a key factor in that decision!
Mahagony would like nice. My 'standard' Mouse came with an alder body. I guess there is no upcharge for body woods. My stock MB2 came with an ash body. My upgraded fretted mouse with Koa top has an alder body.
Hard to beat that maple tope/Goncalo (I can never remember that name!) board with the body wood of your choice.
The F hole seems pretty trivial... more about looks than any particular significant change in tone, comparing my two... one with F and one without. Nice look though, and I believe Rob feels it just opens the tone up a smidge, especially when practicing unplugged.
