Feature:
Adjustable DI out so the PA gets the same tone characteristics as your stage rig. Biult in compresssor. Parametric eq. Everything a bass player needs to to get the tone. Also tube drive.

Quality:
Biult tough but buy rack case. Why spend the money, love it and then drop it by accident.

Value:
Hi resale value. You get what you pay for. Blows away your Hartkes and GKs and has more tone possibilities than Ampeg. Better than Aguilar and SWR in my opinion. You can get snap and great tone from a 4x10 or 2x12 and then add a 1x15 or 1x18 (all Eden of course) to get a ballsy low end. The one amp you will not regret.

Desirability:
Old school boutique look without the boutique attitude.

Sound:
It's all about the tone. Very reliable, however, follow the instructions because this amp draws alot of power. Plug it into its own 15 amp circuit to get the full tone. Unbelievable tone.

Ease of Use:
The instructions and LED lights are very helpful in setting your amp levels.

Support:
Did not have to deal with support.

Overall:
The tone, the power, the features.
