Notes: Valve distortion/saturation unit — classified 'Saturation / Character' per brief guidance, not a typical EQ/compressor. 'The original and still the only studio unit dedicated to just adding valve produced harmonic distortion.' Max gain clean 35dB, overdriven >60dB; distortion range 0.2%–99.5% (official spec PDF, Oct 2005). Country of manufacture confirmed via page's own feature list ('Made in England'). No price published anywhere (site shows 'Call for price'); confirmed no USD price on US distributor site either. Official site thermionicculture.com is currently unreachable/broken (root returns an empty Apache directory listing, product URLs 404) as of research date 2026-07-19; all data below sourced from Wayback Machine snapshot dated 2025-05-16 (and linked official spec-sheet PDFs) of the live Joomla/VirtueMart catalog, cross-checked against the current Independent Audio (US distributor) product listing, which also shows no USD pricing. Per the site's own catalog navigation (Limited Editions / Classic Editions / Discontinued Items), the following are marked DISCONTINUED and were excluded from this current-products dataset: Little Bustard, Freebird, Solo Vulture, Culture Vulture Mastering Plus, Nightingale 2, Culture Vulture CV20A (20th Anniversary), and The Rack (an equipment rack accessory, not audio-processing hardware, made for housing the discontinued Nightingale/Freebird). Freebird and Nightingale were named in the research brief but are NOT current products per the manufacturer's own site.
