Mediums on my Webber Round Body!!!
 

I've had a Webber Roundbody for a year or so. It's a great guitar. I know they come from the shop with mediums but I've always had lights on mine. Today I need a re-string and thought I'd try mediums. Wow, sounds bigger now. Anyone else have the same thing happen?...or is it in my head?

That is what its supposed to do, physics and engineering. More steel (more mass) vibrating at the same frequency equals more energy into the soundboard. Thus, more volume. Its beginner / intermediate rocket science! I think a guitar is a wonderful conglomeration of science, art, engineering, music, and carpentry. Building them is what has captured my imagination and stolen all my spare time for almost 5 years now. I can't stop, number 24 is on the bench right now with freshly glued bindings....

Happily intoxicated, Mikey

Mediums on my Webber Rounbody
 

Definately a difference.
I usually have mediums on mine, but just recently changed to lights for a change of pace.

Considering that most Webbers are built and braced to handle mediums, it's reasonable to assume the change wasn't simply "in your head" :D

I play with a lot of bends and vibrato, though, so the highest gauge I've ever tried was med-light (light top, 0.012" to medium bottom, 0.056"). More recently, I decided to sacrifice some tone for playability and and go back to lights :)

Since changing from mediums to elixir lights (12's) I've really enjoyed my Webber more. Slightly less volume, but the playability makes up for it-- plus the hammer ons, etc are so much more responsive with the lights...
