Been totally happy with Fender Bassman 135 rig for nearly 15 years now. It's just a great platform from which to build pretty much any sound I want. It delivers the sound of the instrument very clearly. I have a bass from 60s, 70s, 80s and 00s. Each produces the sound of its era. Also the Bassman head is awesome as a guitar amp. So I get 2 for price of one.
Oh did I mention the amp cost me £70 from Admag, the 1x15 cab I use was £100 and the 2x15 was £225.
I am v happy with this arrangement!
