Mr. Boost - Two thumbs up!
Written by Stan Dolecki on Sep 19th 2018

In the gear world, sometimes you find something that not only delivers on the manufacturers promise, but actually gives you a little more. I am happily finding Mr. Boost to be one of those products. This pedal is advertised as a “transparent boost”, a “workhorse pedal”, and that is exactly what it is. It brings out more of what is already going on between your amp and pickups. So far as I can tell, it doesn’t add color, but it gives your sound greater presence and dimension. The real treat comes when you plug in and hit the switch. The overall effect of using the pedal in front of my Fender 68 DRR was like having the amp behind closed doors, and finally opening those doors. The sound just got bigger, more defined, and breathier. My test rig was simple - guitar to pedal to amp. Regardless of which guitar I used, which pickup type or position, I found the pedal to have a playable, musical feel to it… the kind that makes you want to keep playing. It enhances play feel rather than impairing it, and I found that the rig remained touch sensitive and very responsive. I was able to make good use of the guitar volume knob to get what I wanted out of it, both sound and feel wise. For me, the gold coin here is that you can pull big sound out of your tube amp at house friendly volumes. Of course that is completely subjective but my wife seems to agree. Sometimes you just gotta run with it. The pedal is straight forward and simple to use. It has the features it needs, and does what it is supposed to do. If you are looking for a quality, great sounding clean boost, and at a great price point, you owe it to yourself to give this a try.
