First up is the MXR MC401. With a true bypass and one goal in mind, this boost pedal is for those who need more boost without any coloration whatsoever. With boost adjustable between 0 and +20 dB, there is a decent amount of variance available, but otherwise, this is a no-frills option that really delivers.

 Joyo Audio RollNext let's have a look at the Joyo Audio Roll. The Joyo Roll Boost is one very interesting little pedal. The boost knob label is expressed only as gain on the front, which somewhat hides the fact that it’s capable of giving you a +35 dB increase. That’s some serious power, which means that whether you use this as part of your effects setup, or just to boost the signal into the amp, you’re going to notice. It works well, adding some extra sparkle at the top end, but it does feel like there’s a little bit of a tonal change. Certainly not bad for the price, which is why the Roll Boost deserves to be on this list.

Design-wise, this is a pretty shallow little unit, but it’s a good looking thing, and it should neatly fit into most boards with ease. Bright yellow might not be to everyone’s tastes, but it fits nicely with the funky aesthetic and rounded edges. Build quality isn’t as high as some of the boxes on this list, but it’s still very competitive at what is an extremely attractive price point.
