The Lava Box is not an ordinary Mosfet distortion/overdrive effect pedal. It actually reacts more like a great amp than a stompbox, with the depth and dynamics that give well-made amps so much character.

When you think about the tones that defined so many of the true guitar heroes throughout history, they all really speak. They cut through. They say something. A huge part of that is in the rich midrange frequencies that the amplifiers of the day naturally produced. And, because those amps were typically cranked up to full volume, they were also incredibly dynamic, responding to different picking attacks and even subtle changes to the guitar's volume control.

The Lava Box brings that magic back with its broad array of midrange timbres and its amazing sensitivity to picking intensity and volume changes. One of coolest features is the six-position Rumble bass roll-off control. This rotary knob changes the sonic character of the Lava Box pedal's distortion for a huge range of tones, from bright and spanky to deep and warm. Whether you have the thinnest single-coil in the bridge of your guitar or the woolliest humbucker in the neck, there is a Rumble setting that's perfect for it.

Even at the highest gain settings, you can turn down your guitar's volume control and the Lava Box guitar pedal will clean up beautifully. Onstage, you can set the Lava Box for a loud lead tone and simply use your guitar's volume control to get your clean and crunch tones”all without switching channels or kicking in other effects. In the studio, you can explore the huge array of tones that are available with the intuitive controls, creating special-effect thin tones or spooky dark sounds that are perfect for layering and overdubs.

Great Hendrix and Cream tone!

By Robert Wessel

from Milwaukee WI

Don't pay too much attention to the description at the Seymour Duncan site or here on this site. The Lava Box does clean up when you lighten your attack, like an amp, but the similarity stops there. Play the riff to Purple Haze through it. Play a blues lick with double stops. You'll hear that dissonant, trippy 60's fuzz hash. My Lava Box sounds great when I'm playing Hendrix or Cream riffs. If I set the 6 position switch to one of the bassier settings, it nails the tone in "Spirit in the Sky". But modern metal? No. 80's metal? No way. 70's AC/DC or Joe Walsh riffs? Absolutely not. It does not have the character of an overdriven tube amp, it sounds like a totally solid state fuzz.

Great pedal,lots of tones to work with.

By Bill Smith

from Cincinnati,Ohio

This is a great pedal-it is also a very powerful is also sensetive to volume control.I like the # 5 position with the volume at 1/3 and the gain at 1/ is reminisent of the Hendrix tone.I feel like it is pretty close to the Tweek Fuzz-when using more gain I feel it sounds very close to the T works very well for cleaner tones that you just want to cut through the mix with.I feel that it is an all around overdrive pedal.lots of tones to be discovered.built like a tank will endure alot of gigging and stomping.

The Lava Box gives you a ...

By Pickles1128

from Miamisburg, Oh

The Lava Box gives you a much louder and more clear sound than any pedal I have ever used!The louder you play it the better the sound comes in, and it tunes itself to sound right. You dont get the reverb fuzz sound at all.
