Frantone Vibutron — Ultra-Rare Amp Like Analog Tremolo/Vibrato 

One of the rarest and most sought-after Frantone pedals ever made — a true high-end analog modulation masterpiece.

For sale is an exceptionally rare Frantone Vibutron, one of the crown jewels of boutique American pedal-building. Long discontinued and increasingly hard to find, this is one of the rarest pedals in my collection — a true collector’s piece that also happens to be one of the best-sounding analog tremolo/vibrato units ever built.

The Vibutron delivers pure vintage amp-style modulation, warm, deep and organic, Intersil ICL8038 with zero digital artifacts and the unmistakable feel of classic Amp tremolos.

• True analog tremolo/vibrato with rich, musical sweep

• No gimmicks, no digital tricks — pure boutique analog tone

• Three waveforms that define the character of the modulation:

• Sine Wave — “Blackface Fender Style”

Smooth, lush, vintage tremolo reminiscent of 1960s Fender amps.

Perfect for clean chords, surf textures, soulful rhythms.

• Triangle Wave

More defined and articulate, great for rhythmic patterns, percussive pulses and ambient textures.

• Square Wave

Hard-edged, choppy, bold. Ideal for dramatic trem cuts, experimental tones, or driving the effect into more extreme territory.

• Full analog control over Speed, Depth, and Waveform, making it one of the most versatile vintage-voiced tremolos you can buy.

• Built like a tank: cast-aluminum housing, premium components, hand-wired quality.

• Players who want authentic, amp-like tremolo/vibrato with zero compromise.

• Studio guitarists who need warm, organic modulation that sits perfectly in a mix.

• Tone purists who care about feel, not features — and want the real analog experience.

If you want a high-end tremolo/vibrato with vintage soul and modern reliability — and you value rarity — this is the one.
