A tuneable boost is a low noise gain stage that pushes the front of an amplifier or pedal in multiple ways by not being limited to only amplifying a single frequency range.

But the more or less is not just a boost circuit. Inside the pedal you’ll find a mode switch that opens up another range of sonic possibilities.

It’s primarily a hi-fi toneshaper designed to affect frequencies just on the edge of and outside the guitar frequency range, making it possible to improve the tone of your guitar without ruining the instrument’s unique and characteristic sound.

It can be used anywhere in the signal chain. At the beginning it can be a buffer but more importantly, it changes the way everything else responds to your instrument and makes your instrument shine right at the start of your setup. Connect it to the output of a fuzz or overdrive to get rid of harsh clipping noise or muddy low end tones. And at the end of the signal chain, it can be a line driver between your pedalboard and amplifier that adds the finishing touch to your sound while making sure you don’t have to worry about losing signal across long cables.

All this shows what the more or less was designed to be. A pedal that makes it easy to get the best sound out of your guitar and that will be missed when it’s turned off.
