Back in the late ’60s – before the Big Muff – Electro-Harmonix came up with a nifty way to boost guitar signal into a guitar amplifier with its LPB-1 Linear Power Booster, a simple one-knob, battery-powered device.
Now, the company has brought the LPB family right up to date with the much more sophisticated LPB-3, still with the same role of boosting the signal from guitar to amp, but this time with some powerful active EQ to complement the boost.
