Untitled. Guitar signal boosters have been a hot item on guitarists' lists ever since Johnny Dallas cooked up the primordial Dallas Rangemaster and set it loose on an unsuspecting world.
While the Rangemaster was a great advance in its day, and more than made up for the shortcomings of the typical low-output pickup of the time, guitarists ever since have chased boxes that could push their amps just a little harder. For a more in-depth read on the Dallas Rangemaster, see Rangemaster - the European Secret Weapon. The next most venerable box in this line is the ElectroHarmonix LPB-1 (Linear Power Booster 1), Mike Matthews' single-transistor entry into the booster sweepstakes.
The LPB-1 was advertised as making your amp sound louder - and perhaps it did, using up whatever headroom the amp had left and driving the bejeezus out of the input. Suitable small MOSFET - Page 2.
