Used but in excellent shape. Not beat up and theres plenty of tube life left. Selling for $550 Plus shipping.

Here's some write up from google:

Designed to combine classic tube bass tone with modern features, the E300T offers a simple control set and a range of tones anywhere from ultra-clean to overdriven grind. At only 54 pounds, it's likely the lightest all-tube bass amp ever made.

Each tube can be separately biased so you do not need to replace a set if 1 fails.
