    I can't say enough about what the Fulltone Fat-Boost 3 pedal does for my tone. Mine is set as a clean boost, but it adds such a nice element to my sound that I almost never turn it off. From a nice boost, to pushing your tube amp into a more full saturation, it just makes everything better!

    Great addition to my pedal arsenal!

    I needed something to beef up the low end and increase the signal from my vintage style strat going into a tube amp. I tried using an OD pedal with the bass turned up, but the tone got really muddy. I was floored when I tried the Fulltone Fat Boost! It adds plenty of low end beef without losing the highs. Don't get me wrong, I like the way the Strat sounds without the pedal for certain things, but I play mostly classic-rock covers and I always felt like I had to switch guitars for the heavier stuff. Now I don't have to.

    I've had this pedal a month, and I am completely floored by it. As of this point its the best stomp box I have purchased. I was looking for a great boost pedal with some extra magic, and this thing has it !!! The extra life it brings to your sounds is so musical, added depth, sparkle, warmth and drive. Don't think I could go with out it now. The way(s) it hits your amp depending on your settings...just sound soooo niice.
    Built like a tank, easy to use and dial in great sounds. Don't think its coming off my board ever! Many thanks fulltone and sweet water.

    It does what you'd expect, and does it well!

    I've owned other Fulltone pedals and this one is no exception. It is, by far, one of the best boost pedals that I've ever used. Rock-solid construction and first-rate components should provide years of worry-free use. I love it!

    great sound, no fuss

    Nice boost: can be clean, warm or gritty. With a non-master volume tube amp, this pedal is a life saver for those gigs where they keep telling you to turn down. You can turn up the drive, leave it on and simulate a pushed amp at lower volumes. It is most transparent with Bass and Treble dials all the way up.

    Fulltone Fat Boost 3

    Wow! I already like my clean sound and slightly gritty sound, but this thing takes it to the next level. It's keeps your sound, but has that MORE ME thing that makes all the difference. Quality construction and parts, quiet switch, doesn't add load.......in fact, placed at the end of my pedal chain, it restores the life in the sound. Excellent product!!

    Worth the wait!!

    Great boost pedal. I waited a long time for it, but it was worth the wait. If you already love the tone of your rig, and just want a kiss more on tap. Then this is the pedal for you. I use it with a Bogner Ecstasy, and couldn't be happier. Everything gets bigger when you stomp on it!LOL!

    If it's Fulltone,.. it's quality

    I've been buying Fulltone pedals since the late 90s and have never been let down. This pedal does exactly what it's supposed to do. I also like the the overall build og Mike Fuller's pedals... they're "tank tough."
