hey guys, a curious question from a lurker. first a little background. i am strictly a hobby player and i play along with cd's in the spare bedroom. i do have a nice bass, though, for what i do. it is an old carved pfretzschner that i got as a gift a few years ago and had restored. i mentioned it in this forum at the time. it is the only double bass i've ever played and the only one i know. i've never been to analytical about the thing, i just play it for fun. lately i've been reading through this forum and am amazed at the wealth of information here! it's been a lot of fun and after reading the technical details about so many basses it made me more interested in my own. so i pulled out the tape measure just to compare the dimensions to other basses just out of curiosity. the results prompted me to ask a few questions- upper 20" lower 25" rib depth 8" body length 44" scale 43" it seems the bass is a 3/4 size with an abnormally long scale length compared to others i've read about. i know there are no hard and fast rules when it comes to double bass dimensions, but i was curious if this was outside of standard specs? does scale length or body size determine bass size? in theory, what does a longer scale/ smaller body have to do with tone? any of you experts willing to humor my trivial questions? thanks!
