Anybody who know Roma

The reason why I ask is that I'm going there in a few months and I wanna know where the music/bass stores are. Last year I went to London and saw a nice Musicman and not too expensive. In fact it was less than half of the price that it costs here in Denmark. I regret that I didn't buy it but maybe I'll get another opportunity in Roma. Please tell me where to buy basses in Roma.

Thanks
Loui
