Luke Pabich, former guitar player for Good Riddance, has put together his own little acoustic project he calls Outlie-Acoustic. You can listen to a few of his songs by going to his myspace page. You can also check out some of his amplified songs by clicking here.
Sadly, Good Riddance is no longer together. They had an amazing career all the way from 1993 to 2007 while signed to Fat Wreck Chords.
