Firstly, please forgive my complete ignorance on the matter of DB. I am currently a fretess bass guitar only player looking to buy an upright sometime this year. I will be playing rockabilly, bluegrass, etc. My question is about choosing the right size. I have found a 4/4 for sale for a decent price. I am 6'4" barefoot and have fairly long fingers. Would 4/4 be more appropriate for me or should I stick with the 'standard' 3/4 size? I know condition and playability matter most but I need advice from others strictly on size at this early stage of investigating DB. I have plenty of space and a big enough vehicle to haul it so that's not really a concern. What are some pros and cons of each size? Thanks in advance.
