A handwired treble booster with three dynamic settings for maximum tonal range and built upon the NOS OC44 transistor.

Los Angeles, CA (November 21, 2017) -- Just in time for the Holidays, Massive FX Pedals announces the DallasDevilsPlay “Krampus Limited Edition” treble booster is now shipping! The DallasDevilsPlay honors the classic OC44 Treble Booster but with a few new sonic twists.

The DallasDevilsPlay is a hand-wired treble booster with 3 dynamic settings for maximum tone range, imparted by a NOS OC44 transistor. The DallasDevilsPlay’s circuit is our take on the legendary Dallas Rangemaster with a few new tricks. Mode 1 is the standard vintage treble booster, Mode 2 is slightly scooped in a “Sabbath” kind o’way, and Mode 3 is a super heavy scooped mid-producing massive low-end doom/stoner rock voicing. This 1 st edition “Krampus Limited Edition” treble booster will be limited to 100 hand-numbered units.

DallasDevilsPlay controls include:

  • Master Volume
  • Mode 1 "Vintage Treble Booster" Mode. The unmistakable classic OC44 Treble Booster tone similar to the tone on many Queen tracks, and “rumored” to be used on the Blues Breakers “Beano” recording featuring Eric Clapton. Your tone will cut through anything like a hot knife on butter.
  • Mode 2 “Tony” Mode. This mode is only to be used after dark on the Sabbath.
  • Mode 3 Max “Hell” ON Mode. Extra heavy mode suitable for Doom and Stoner rock.

The DallasDevilsPlay expands Massive FX Pedals 2017 product line. Additional models coming soon will feature classic designs with modern features. All component and design decisions are based on tone with emphatic disregard for cost or compromise resulting in stunning tonal excess.

DallasDevilsPlay controls include:

  • Hand crafted in Los Angeles, CA USA
  • 100% Analog in design, several models utilize rare NOS vintage components such as AC125 and OC44, and hand matched silicon transistors.
  • High-end components such as Lumberg “enclosed” input/output jacks and Potentiometer dust caps for years of noise-free operation.
  • Unique artwork and hand-applied finish on Powder Coated enclosures
  • Limited Edition 100 total “Krampus Edition” DallasDevilsPlay pedals. Each pedal’s inside back plate is hand numbered by former “The Simpsons” cartoonist/artist Tom Winkler in debut versions of Massive FX Pedals.

Pricing for the DallasDevilsPlay ™ OC44 Treble Booster is $199.

TC Electronic SCF Gold


When you consider stompboxes that have achieved ubiquity and longevity, images of Tube Screamers, Big Muffs, or Boss’ DD series delays probably flash before your eyes. It’s less likely that TC Electronic’s Stereo Chorus Flanger comes to mind. But when you consider that its fundamental architecture has remained essentially unchanged since 1976 and that it has consistently satisfied persnickety tone hounds like Eric Johnson, it’s hard to not be dazzled by its staying power—or wonder what makes it such an indispensable staple for so many players.

While Monolord has no shortage of the dark and heavy, guitarist and vocalist Thomas V Jäger comes at it from a perspective more common to pop songsmiths.

Melodies, hooks, clean tones, and no guitar solos. Are we sure this Elliott Smith fan fronts a doom-metal band? (We’re sure!)

Legend has it the name Monolord refers to a friend of the band with the same moniker who lost hearing in his left ear, and later said it didn’t matter if the band recorded anything in stereo, because he could not hear it anyway. It’s a funny, though slightly tragic, bit of backstory, but that handle is befitting in yet another, perhaps even more profound, way. Doom and stoner metal are arguably the torch-bearing subgenres for hard rock guitar players, and if any band seems to hold the keys to the castle at this moment, it’s Monolord.
