Welcome, you are looking at a great piece. This is the Electro-Harmonix LPB-1 boost pedal! These LPB-1 pedals by EHX are exact recreations of the famous circuit that brought in the era of distortion and saturation in 1968. This little pedal is one of the best things you can get for your guitar tone. In front of an overdriven amp, the LPB-1 will fatten your tone, saturating it and adding gain for a thick creamy sound. As a clean boost, it will boost volume substantially - perfect for standing out in the mix. Check out the video link to see what a big impact this little pedal makes! We are an authorized Electro-Harmonix dealer. Don't pass this by!
