Description
The Power Boost is a pre-amp booster and EQ in one. The early models didn’t have a master volume, but the 18V powering provided plenty of headroom and power. You could drive the front end of your amp and use the treble and bass controls to shape your tone or compensate for anything lacking in your amp. The Power Boost also made it possible to achieve overdrive or distortion on smaller amps, without having to drive the pre-gain tubes. The Power Boost has a distinctly scooped tone, meaning that there really isn’t much mid range nor compression going on. Its open and transparent tone is really the secret to be able to drive those old Hiwatts and Marshall heads for smooth, singing overdrive and distortion. The silicon transistor based circuit creates a fat low end and glassy top, with lots of sweet sustain.
