Your Distillate is in awesome condition!
Love the Koa top/Mahogany back and brass plate and also their condition(s).
I am the original owner of an '81 Distillate, having the top ordered in Purpleheart; however the patina with age, UV, (and the type of clear coat they used to use), has the color almost to Brown in hue. Be careful to put your 1/4 instrument cable through the strap as the top around the jack on my bass is cracked due to accidently stepping on the cord a long time ago. I\m not the only one with a Distillate to have this happen.
Enjoy the sounds you\ll get out of this instrument. Are you going to get the electronics upgrade to increase output/and I think to also reduce the possible noise generated from all the cell phones and such in use today since 1981? There is a thread in part about this upgrade.
