Thanks for the comments guys. Although I have no experience of the feel of a well set up instrument, nothing feels wrong at the moment, and the bass is quite playable, so I am going to wait a bit for the set up.
I am not sure of the type of strings I want to put on the instrument yet, so it would make sense to delay the set up until I have stopped faffing about and reached a decision. The fingerboard has a bevel for gut strings, so I am increasingly thinking of putting gut strings on. Any suggestions of brands - good or bad?
