Here's a spreadsheet I've worked on for about 2 years using info gathered on Talkbass. There 323 basses in it.
If you want to add your info to the list, please post it here, giving me the following info:
Manufacturer - Year - Model - special features - weight (pounds & ounces; 8 pounds 4 oz would be noted as 8.4)
Example:
Fender 1963 Precision Bridge/PU covers 8.3
I'm aware that some of the info is a bit "off", but I'm not an expert on basses. If someone told me it was an Ernie Ball, that's how it's listed. If they told me it was a Musicman, that's how it's listed. People use some of the damndest abbreviations to describe basses, and I don't understand many of them.
There are very few Gibbys, and only one Tbird. If you want to that info, I'll add it.
