My Friend is selling her Bass Amp it's a Jasen, but thats all I could tell ya right now.

I know of a bass amp by Thunder Funk. It's 400-watt and as excellent sound quality.
The average pricing said on his website that it starts at $1,195. 00. But you can get one over Ebay from him, which he is selling for $850. 00.
If you want more information, then check out his website. You can look for it on Google, look of thunkfunk, and you'll find it.

Hope you find the one! ^_^
