The Tony Bassett No 1 Electronics Theremin is a legendary piece of boutique electronic craftwork that has fascinated experimental musicians, avant-garde sound designers, and collectors for decades. Built by legendary British inventor Tony Bassett from his workshop in London's Camden Lock, this compact instrument represents a unique chapter in analog synth history, bridging hand-wired innovation with iconic status—even finding a permanent home in the private studio of filmmaker David Lynch.
Understanding what makes this custom-built instrument so compelling requires looking past generic summaries and exploring its distinct circuitry, physical build, and precise control mechanics. Unlike mass-produced factory theremins, Bassett's creations relied on artisan craftsmanship, custom enclosures, and idiosyncratic tuning pots that gave each unit its own sonic personality.
Craftsmanship and Portable Design
The physical architecture of a Bassett creation departs significantly from traditional multi-antenna, wooden-cabinet concert theremins. Most units manufactured under the No. 1 Electronics banner featured a compact, utilitarian grey or dark-toned plastic enclosure housing the core oscillator circuit, complemented by a single protruding metal whip antenna (often around 6.5 inches).
This portable design traded orchestral range for intimacy and performance flexibility. Powered typically by a standard 9-volt battery rather than heavy AC wall adapters, the unit was engineered for mobile sound manipulation. Rear panels often featured Bassett's signature iridescent pink "Space Trip Passport" labels, stamping each device with his distinct London workshop pedigree.
Circuitry and Heterodyning Mechanics
At its electronic core, the Bassett No. 1 operates on the classic heterodyning principle pioneered by Lev Termen, mixing two high-frequency radio oscillators. When a player's hand approaches the single antenna, changes in capacitance shift the frequency of the variable oscillator. The resulting audible difference frequency creates the iconic glissando tone.
However, Bassett's circuit modifications introduced distinct operational quirks:
- Tune Control: A dedicated tuning knob on the front panel regulates the fundamental pitch range, allowing players to scale the sensitivity field.
- Proximity Response: Due to the compact antenna geometry, the spatial sweet spot requires immense physical discipline, rewarding minute finger adjustments rather than sweeping arm gestures.
- Analog Instability: Like many hand-built analog devices, thermal drift is common, meaning players must account for ambient temperature shifts during tuning.
Real-World Usage and Notable Collectors
The appeal of No. 1 Electronics gear extends far beyond niche hobbyist circles. Because Bassett custom-built his instruments for working musicians and sound artists across London's experimental scenes, many units ended up in professional hands.
Most notably, a vintage Tony Bassett No. 1 Electronics Theremin from the personal estate of acclaimed director and musician David Lynch was featured at auction via Julien's Auctions, highlighting its status as a prized studio tool for creating dark, cinematic atmospheres. Artists seeking raw, organic frequency sweeps appreciate how easily these battery-powered units integrate into pedalboards or mobile recording rigs.
Common Mistakes When Playing a Single-Antenna Theremin
If you encounter or acquire a vintage single-antenna Bassett theremin, avoiding common performance traps ensures better musical results:
- Ignoring Thermal Warm-up: Powering on the unit and playing immediately leads to constant drift. Give the analog circuit five to ten minutes to stabilize thermally.
- Standing Too Close: Body mass affects capacitance. Standing too close to the enclosure itself disrupts the grounding balance.
- Expecting Massive Octave Ranges: Single-antenna setups designed for portability offer tighter, more expressive micro-tonal ranges rather than the sweeping multi-octave spans of concert-grade studio models.

Frequently Asked Questions
What makes the Tony Bassett No. 1 Electronics Theremin different from standard theremins?
Unlike large concert models with separate pitch and volume loops, Bassett's units typically utilized a compact, battery-powered single-antenna enclosure emphasizing portability and raw analog character.
How do you power a vintage No. 1 Electronics unit?
Most models operate on a standard 9-volt battery housed inside the rugged plastic chassis, making them completely self-contained for field recording and mobile setups.
Are these instruments still manufactured today?
No. Following Tony Bassett's passing, original No. 1 Electronics units have become rare collector's items, frequently appearing in specialized high-end music auctions and private estates.
Can you play melodies accurately on a single-antenna theremin?
Yes, though it requires advanced spatial control. Without a dedicated volume antenna to cut notes cleanly, players rely on precise finger muting techniques and subtle proximity shifts to articulate individual notes.
