I went through a phase of just buying and selling in order to find out what I like, especially with 5 strings. I managed to trade my way up to having an Overwater J5 and a Warwick thumb NT fretless 5, but had to sell them for financial reasons and from then on decided to stick with four strings. I’ll go back to a 5 but it has to be the perfect bass as I don’t really need it.
