While it may not provide a clean octave-down sound like digital pedals, it excels at fattening up riffs and solo notes.The original Blue Box had limited gain capabilities, but FuzzDog Labs has included a post-boost in the Blue Fool to make it more usable and enjoyable. This boost allows you to achieve higher gain levels and adds a lovely touch to your sound.Additionally, the Blue Fool offers the ability to switch between one or two octaves down, making it a more versatile pedal. However, if you prefer a fixed setting, you can hardwire it for either option and eliminate the need for the switch.Overall, the Blue Fool – MXR Blue Box+ is a quirky and glitchy fuzz pedal that can add a unique flavor to your guitar playing. It is particularly great for fattening up riffs and solo notes, and the added post-boost and octave options make it even more versatile.
