This pedal is often used as an always on pedal to make everything sound better. But it's also great when you just need that boost during a song or solo. It's perfect or enhancing what's already there in your amp / pedal setup. It just adds more body / punch / push. Typical EHX build quality and reliability. Can also take a 9v power supply.
