Monster Effects

Monster Effects is the creation of electronics whiz, John Spears. John combined his obsession for the brown face tremolo sound and his electronics experience to create the original Swamp Thang. The response to the unit inspired john to launch Monster Effects in 2001. Since it's inception, the Swamp Thang has become a favorite among touring musicians and studio types as well.
The Mastortion pedal and it's no holds barred tone was designed for the fellows from Mastodon and it sounds exactly like it should. Ragingly heavy!!
2005 brought along the creation of Atom Amps, which specialized in the building of boutique, point to point, hand built amps. Atom Amps is a collaboration between John and the best guitar cabinet builder around, Larry Rodgers. All products are hand built in the U.S.A.
