Today's couple are two of my instruments with pickguards. Definitely a great way to make an instrument more classy...
Kiesel PB4 / Ibanez RG2077XL
I only got the Kiesel this year and was finally able to have an instrument in surf green and with a tortoise pickguard built. That's a combo I wanted for the longest time and this bass was a great opportunity to make it happen.
The RG2077XL has a pickguard for practical reasons: It used to be H-S-H, which I find aesthetically unpleasing and the middle pickup gets in the way of my picking. The pickguard, which is attached to the guitar with double-sided tape, eliminated that and definitely improved the looks of the guitar.
