EarthQuaker Devices Dunes

"The Dunes, like the Palisades, is a Tube Screamer variant. Yet it goes a step further from the original, adding a few extra features that go a long way to matching your guitar and pickups, to your amp. The knobs are familiar—Tone, Gain and Volume. In addition, there are three toggle switches that really make things interesting:
Voice: Gives you three tonal differences; MOSFET, Silicon and Normal. These options give you different levels of compression when adding gain, and really change the overall character a lot. The Normal setting has little to no compression if that is desired.
Normal/Bright: Works great when using either darker humbuckers—switch to Bright, or if using single coils, keep it normal. Using the master tone control in conjunction with this switch gives you a lot of useful variation.
Bandwidth: What a traditional Tube Screamer lacks—here, the Dunes gives you the option of adding a lot of deep low end—great for single coils, or switch it back to the more traditional screamer mode, accentuating the midrange, with less emphasis on the bottom end."
