I have 3 different fivers with different neck sizes A tobias growler with 17 mm A stingray with 17.5 mm A fender roscoe beck with 19 mm The fender was the last bass I bought and it is my regular bass for gigging, rehearsing and recording. I was difficult at first to play it because it is wider but then I love that size and the tension it gets. It is a bass to groove and it can get different dynamics easily. The growler on the contrary is a bass for kids comparing it to the fender. It feels strange now to play it and I can get less dynamics from it. It has great tone but way more compressed and modern. What is your experience?? Do you have different size basses?? Can you play them confortable if you change basses regularly??
