http://earthquakerdevices.com/ The Earthquaker Devices Spires Is a 2 channel Fuzz box with 2 distinct voices and plenty of ripping fuzz. The green channel is Earthquaker's take on the Rosac Electronic Nu-Fuzz and has a Full on Fuzz sound with controls for volume and tone. The red channel is Earthquaker's discontinued Dream Crusher but it is now a more stable Silicon version. The red channel has controls for volume and fuzz. The entire range of the fuzz dial is extremely usable. If you want two distinct fuzz tones on your board while saving space, the Spires from Earthquaker Devices is the ticket!
