This may seem an odd request, but I can't figure any way to find this out with out having both in my possession.
I am a bassist primarily, & have been for 45 years or so. I play electric & haven't played upright since my teens... 40 years ago.
I have a gig coming up playing string bass. It's for a movie so I'll only be miming.
I won't have an instrument until the week of filming most probably, so I'm trying to come up with some method of at least approximating the finger positions for each note, just so my surprise/fear isn't total when I first pick up the upright ;)
At the moment I'm doing exercises where I'm treating 2 frets as one [you wouldn't want to listen to it, but it gives me a feel for the longer scale].
Would anyone possessing both an electric & upright [I'm going to have to assume it will be a 4/4 not a rockabilly 3/4 size] be able to approximate the actual relative positions of maybe the first 7 'frets' on an upright as compared to a regular electric?
I know it can't be accurate, but if someone could even confirm treating 2 frets as one will do for now in terms of simply how far I need to be reaching to approximate the correct position, that might be a start.
Just to be clear, I'm not talking about matching the 'notes' merely the fret positions/distances for a visual-only guide.
