Seems like whenever I see any of these vintage Fender Bassman heads, they're being used on guitar. I get they sound good that way, but do they sound good on bass? I'm looking for a head to give me lots of tube warmth, maybe a bit of grit when I want it to. These vintage bassman amps seem like an economical option as I love vintage stuff. I'm just wondering if there's a better option for bass around the same price range ($500). Any suggestions?
