Why did the early 70's just plain rule for bass amps? The other day I was in Somerville at the best fricking place in the world to get used bass gear, and I plugged into three absolutely awesome and yet distinct amps. The three amps were a Kustom 250, an Acoustic 270 and an Ampeg SVT from 71. All three of the amps just flat out blow away 99% of most new stuff. First place: The Acoustic 270. This amp has the power amp section in the bottom of the cabinet and a reverse facing 15" in the bottom. This thing is genius. I couldn't get myself not to sound like John Entwhistle. The tone out of this thing was so beautiful and colored, you couldn't get the amp to sound bad. Second Place: The Kustom 250. This may have been the most versatile, yet most rocking amp ever. Who knew? I think it had a 4x12 cabinet, I can't remember. This amp can do everything, from subtle flatwound thump, to slightly scooped funk see Bootsy Collins, to full blown rock grind. There are hardly any amps made today, that do the latter. This is my issue with modern amps. Third place: 71 SVT. If you don't know what they sound like by now get out and find one. I put the blame for new amps mostly sucking square on the shoulders of smooth jazz people that were always pushing for more clean headroom and no midrange to speak of. You people ruined the bass world for those of us that want to rock. Even Ampeg doesn't make an amp that sounds as cool as any of these. I love solid state power sections and how wonderfully light they can be, but there isn't a modern amp out there that can hold a candle to any of these things. Someday the bass community will wake up and demand more.
