Greenhouse Effects is an Israeli boutique pedal company founded in 2010 by Roy Zichri, an electrical engineer and PCB designer whose layouts have been used by brands such as JHS, Darkglass Electronics, and Wren and Cuff. What began as a hobby building effects for personal use grew into a full-fledged operation known for bold artwork, heavy-duty folded steel enclosures, and handmade construction built to withstand professional touring.

The lineup spans a wide range of effect types, including the Remedy germanium fuzz, the Sludge Hammer doomy fuzz, the Sonic Orb phaser, the Logos chorus/vibrato/multi-modulator, the Deity reverb, the Drifter tremolo, the Entity delay, the NoBrainer distortion, and the Outlier overdrive/distortion. One of the brand's most distinctive offerings is the Self-Titled, a true-analog modular pedal platform that lets players swap between overdrive, fuzz, tremolo, and boost circuits without soldering — each module slides in and out of the same enclosure. The more affordable Roots Series provides entry-level fuzz and echo options with a simplified feature set.

Greenhouse Effects has 11 products cataloged on Equipboard, including Overdrive Effects Pedals, Fuzz Effects Pedals, and Distortion Effects Pedals. Their gear is featured by 3 artists, with the strongest followings in Rock, Metal, and Folk, World, & Country. Notable users include Misha Mansoor, Samantha Crain, and Jackson Phillips.
