Founded in 2006 by Greg Djerrahian in Montreal, Canada, SolidGoldFX is a boutique effects pedal company specializing in handbuilt guitar and bass pedals. Djerrahian left a corporate career to pursue his passion for vintage effects, aiming to blend the warmth of classic circuits with the clarity and reliability of modern electronics. Every pedal is designed and assembled in the company's Montreal workshop by a small team of builders and engineers.

SolidGoldFX's lineup spans a wide range of effects, including the Imperial MKII fuzz, the EM-III multi-head octave echo, the Surf Rider IV spring reverb, the If 6 Was 9 BC183 fuzz, the NU-33 vinyl engine (chorus/vibrato), the Commodore overdrive, and the Lysis MKII polyphonic octave fuzz modulator. The brand also produces the Ether modulated reverberator, the Oblivion quad flanger, and the Supa Funk envelope filter. SolidGoldFX acquired fellow Canadian pedal brand Diamond Pedals, and both lines are now manufactured under the same roof while remaining distinct product lines.

SolidGoldFX pedals are used by a diverse roster of artists including Dallas Green (City and Colour), Dweezil Zappa, Stephen Carpenter (Deftones), Justin Meldal-Johnsen, "Captain" Kirk Douglas (The Roots), Monte Pittman, Jeff Waters (Annihilator), and Tommy Guerrero, among others.

Solid Gold FX has 64 products cataloged on Equipboard, including Fuzz Effects Pedals, Overdrive Effects Pedals, and Reverb Effects Pedals. Their gear is featured by 15 artists, with the strongest followings in Rock, Pop, and Funk / Soul. Notable users include Eirik Stordrange, Rich Ward, and Dweezil Zappa. Most Solid Gold FX products fall in the mid-tier range — professional-grade without flagship pricing.
