I reject the notion that PRS's are embarrassing. I would say an "embarrassing" instrument is a cheap-ass Indonesian made Strat, or other such poor quality guitars. But since it's all about "image" with many here, that's apparently not the definition.
Therefore, I suppose I own a shitload of instruments that are "embarrassing"
Early 90's Kubicki X-Factor bass.

Mine's fretless. How's THAT for douche points??
These basses sound and play fantastic. The build quality, fit and finish are a 10 on a scale of 1 to 10.
Late 80's Ken Smith BT Custom

Mine's a 4-string, not a 5.
Another incredible bass. An absolute work of art, and maybe the best sounding bass ever.
Mid 80's Alembic Spoiler

Super nice. Kinda heavy, but beautifully made and good sounding and playing.
Late 80's Warwick Thumb bass -

Again, very heavy for it's small size. But beautifully made and superb sounding.
Mid 90's Pedulla Rapture 5-string

That's right. 5-string. In metallic purple!! Go eff yourself!!!
