Late 1960s advertisement for the Baldwin Exterminator guitar/keyboard amplifier. The Exterminator was a large amp; solid state with six speakers of varying sizes! Baldwin guitars and amplifiers were distributed by Gretsch at this point.
We've breathed life into this one, so stand back! We call it "The Exterminator." It's a solid state powerhouse that comes on with a wail of sound - six speakers. Two 15, two 12, and two 7 inchers. It puts out a screaming treble that is almost unreal, and a boss that roars right through anything in its path. 250 watts of peak music power. That'll fill any room you're playing from gyms to sports arenas, all the way to open air coliseums. "The Exterminator." It delivers! Try it!
