What type of design moves outward from a central point. do not answer if you don't know

It's the radial balance. 
Hope this helps!

Ibelieve so yes. the industry for electric guitars (such as gibson, fender, prs, epiphone,ect) has went down over the past few years so i feel things will come back up for the vintage style electric guitar (such as the gibson les paul, fender stratocaster/ telecaster, gibson sg, gibson flying v,) so i feel like they will be bringing more vintage style instruments to the stage-jaydoe

Not 100% sure on the answer but i’d say universal as i don’t see why it would be in the definition
