Limited-Run Portland Boutique Class-A Preamp & Harmonic Booster — Serial #7
The Guitar Sanctuary is proud to present this rare Preowned Spaceman Effects Atlas IV Preamp Booster Pedal in its sleek Grey finish—hand-numbered Serial #7 from its limited Portland, Oregon production run. Engineered by Spaceman Effects to capture the warm, three-dimensional harmonic richness of vintage console preamps and classic tube input stages, the Atlas IV is an extraordinary tone-shaping foundation and clean-to-gritty boost for discerning players.
Built around a refined discrete Class-A circuit topology, the Atlas IV delivers up to +23dB of ultra-musical, touch-sensitive boost that pushes tube amplifiers into lush natural overdrive while preserving pick attack and string separation. Even at unity gain as an "always-on" tone enhancer, it adds subtle harmonic bloom, depth, and studio-console polish to single-coils and humbuckers alike—while the tactile Tone toggle lets you tailor low-end fullness and upper-midrange presence to match any guitar or amp pairing.
This preowned example (SN 7) comes to us in Excellent condition with velcro cleanly installed on the bottom plate for immediate pedalboard integration, and includes the complete original Spaceman Effects packaging: factory box, custom cloth drawstring bag, and original paperwork/certificate.
