StrAmp WindWorks Design is pleased to introduce StrAmp, a compact, lightweight stereo booster preamp for guitars, basses, and synths.

Based on our aclaimed FET Booster preamp, the StrAmp is a two channel, AC powered preamp designed to work with the stereo gear like synthesizers and line level gear, as well as guitars and basses. StrAmp lets you get a hotter signal from your instrument to your amp, whether you want a clean, smooth boost in gain, or faster distortion. This unit is super simple, lightweight and small, about the size of a deck of cards, and runs from an included 9V AC power adapter, or any 2.5mm center-positive 9-15Vdc wall power adapter (wall wart). Just like the mono FET Booster Amp, this tiny stereo preamp offers up to 14 dB of mid-bass boost and 8.5 dB from 10KHz out to 40KHz! The incomping power from the wall wart is regulated and filtered to ensure the stereo amp is as quiet as possible.

StrAmp hook up

Input and output connectors are standard 1/4" jacks. Just plug the StrAmp between your instrument and any amp, or just about anywhere in the audio chain where you want extra gain with a mid-bass boost. This little amp works exceptionally well with synths and line level audio gear, providing a bigger bottom from the mid-bass boost. Guitar and basses also benefit; any place where you need clean boost to a signal, the StrAmp will work well.

StrAmp hookup Since StrAmp is really two independent mono chanels, so you can wire it up into several configurations. Plug the output of the left channel into the input of the right channel and you get a double boost: twice the gain for a monster sound. Or take a single mono input such as a guitar and use a "Y" cable to feed both inputs for two independent boosted outputs. With this twin channel arrangement, you can send your mono signal through two independent audio chains. Guitarists tell us of running one channel straight into their amp, and the other through a pedal chain then into a different amp. Imagine the possibilities through your own rig!
