Fender Musicmaster Bass amp FS or trade - $550

Looking to sell or trade my 70s Musicmaster Bass amp.
6v6 version.
Original speaker but tubes are all new Tung Sol.
3 prong.
Good cosmetic condition, with just a couple issues in the tolex on some of the bottom corners.
Ideally would trade for a cheaper amp + cash.
Let me know what you have.
If trading pure cash, looking for $550.
Can include 2 extra brand new tubes (6v6, 12ax7) as well.
Pickup in East nashville.
