I definitely prefer chambered ash bodies. I have two solid body ash axes, one guitar and one bass. And I have one chambered ash guitar.
The chambered ash guitar is perfect. The solid body guitar is paired with a roasted maple neck which makes it a reasonable weight and it really sounds great.
The solid body ash bass on the other hand is heavy as hell. It's paired with a thicker p-bass neck profile that's also a heavy wood, bubinga. Both the body and neck are anchors, it's an avid neck diver and the whole thing weighs about 13 pounds. It's a great practice or studio bass, but too heavy for use on stage outside of a song here or there. I call that bass the Brickhouse.
I used to have another ash bass, it was a chambered body paired with a thinner Jazz bass neck profile with bubinga. I sold it to a buddy of mine and ex-bandmate back in 2009 or 2010. I miss that bass. Chambered ash is the way to go.
All my future ash bodies will be chambered, no doubt.
