I’m selling a quad of Electro Harmonix EH300B Gold Grid. This tube is a monter of reliability.I can split into pairs for half the price.They have low hours on them. Around 500-600 hours.
At A$525, this is way above the usual used market for comparable AUD listings: the median is A$34, the 75th percentile is A$72, and this ask is far beyond even that top quartile. By your database yardstick, it reads as ambitious to the point of needing a very specific justification.
That only makes sense if there’s something exceptional here: a true matched set, rare NOS stock, strong provenance, or a buyer who specifically needs this exact item and understands the premium. If it’s just a standard used listing in unknown condition, I’d want much more detail before treating it as a serious buy; otherwise, the upside is mainly for collectors rather than value hunters.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Electro-Harmonix, founded in 1968 by Mike Matthews in New York City, emerged from the psychedelic rock era with a modest $1,000 investment. Matthews, a former IBM employee with a passion for guitar effects, debuted the LPB-1 Linear Power Booster at that year's NAMM Show, kickstarting a legacy of innovation. Building on his earlier Foxey Lady fuzz sold to Guild Guitars, the company quickly pioneered affordable pedals that shaped electric guitar tones during the late 1960s and 1970s.
The brand focuses exclusively on effects pedals for electric guitar and bass, eschewing traditional hi-fi categories like amplifiers, speakers, turntables, DACs, headphones, or cables. Iconic models such as the Big Muff Pi fuzz, Small Stone phaser, Electric Mistress flanger, and Deluxe Memory Man delay defined its output, with reissues maintaining relevance today. After a hiatus producing vacuum tubes in Russia under Sovtek, Electro-Harmonix revived its core pedal lineup in the 1990s.
Electro-Harmonix holds a niche, mid-tier position in the guitar effects market, revered by musicians and collectors for its vintage-inspired, high-value stompboxes rather than high-end audiophile gear. Pedals like the Big Muff remain staples for artists from Jimi Hendrix to modern players, blending accessibility with tonal influence that punches above its price point.
