The Subdecay Vagabond Tremolo is an all-analog tremolo pedal from US builder Subdecay, announced in April 20171. Its idea is simple: instead of one tremolo circuit, it carries two, modeled on the two classic tremolo styles found in different species of vintage Fender amplifier, the Blackface and the Brownface2. A mini-toggle on the top of the pedal selects between them2.
Subdecay describes it as "tremolo with vintage personality fused with added depth, more speed and more control"3, and it was the builder's first tremolo, developed through years of experimentation and exploration of ideas3.
Bias and harmonic tremolo in one analog pedal
The two modes are the heart of the pedal. Gearnews explained the distinction when the Vagabond was announced: in Bias mode the pedal mimics the classic Fender Blackface tremolo effect, while the Harmonic mode is closer in sound to the older Brownface Fender amplifiers2.
Subdecay's own description of each style, from its product page:
- Bias tremolo: "Bias Tremolos, like some Fender black face amps create subtle distortions and alter frequency response." In bias mode the Vagabond cuts the volume down to zero for maximum throb5.
- Harmonic tremolo: "They were cross fade effects between high and low-pass filters. Because of the phase shift in the filters, they often ha[ve] subtle hints of phaser or vibrato"5. Gearnews likewise described harmonic tremolo as a crossfade between a high and low-pass filter that sounds closer to a vibrato than a tremolo2.
| Mode | Based on | Character |
|---|---|---|
| Bias | Fender Blackface tremolo circuit | Classic volume-cut tremolo; at maximum intensity the volume cuts to zero25 |
| Harmonic | Fender Brownface tremolo | Crossfade between high and low-pass filters, with hints of phaser or vibrato25 |
The circuit is all analog3, and it is true bypass, which Gearnews pointed out means that "unlike a lot of older tremolo pedals it won't suck your tone when not engaged"2.
"The Vagabond delivers two different distinct flavors, harmonic and bias, in a single pedal"
Speed and intensity are said to go beyond classic amp design limitations for maximum throb and chop, and at the maximum intensity setting the pedal gets near square wave modulation4. Subdecay also notes that new ideas are tested on a Princeton Reverb, the amp the builder uses to try out tremolo designs4.
The controls, including the Env Drift knob
The Vagabond keeps its control set small. The core knobs are Speed, Intensity and Volume2, plus the mode toggle and the drift control.
| Control | What it does |
|---|---|
| Mode toggle | Mini-toggle on top, selects between the Bias and Harmonic circuits2 |
| Speed | Sets the tremolo rate2 |
| Intensity | Sets the depth; at maximum the pedal reaches near square wave modulation35 |
| Volume | Dedicated external knob that helps make up for perceived volume loss35 |
| Drift | Envelope speed control: pick attack can slow down or speed up the tremolo35 |
The drift knob is the unusual one. Subdecay calls it an envelope speed control: "Pick attack can slow down or speed up the tremolo by using the drift knob"3. Gearnews described the same control, labeled Env Drift, as allowing "the player's pick attack to either slow down or speed up the tremolo effect"2. In practice it ties the tremolo's motion to your playing dynamics rather than leaving it at one fixed rate.
Subdecay notes that the Quasar phaser's mode 7 offers similar envelope-controlled functionality to the Vagabond6, for players comparing envelope-driven effects.
Power, versions and B-stock
The pedal is listed at $169.00 USD, with B-stock (blemished) units at $149.00 USD45. Blemished pedals are fully functional and carry the standard 3 year warranty, but all blemished pedal sales are final5.
The Vagabond has been sold in a standard finish and a Black version, both at $169.00 USD43.
Subdecay has also sold B-stock Vagabonds: blemished pedals that are fully functional and include the standard 3 year warranty. Blemishes may include paint scratches, silk screen errors, older style graphics or superficial damage, and all blemished pedal sales are final. B-stock units were priced at $149.005.
Where it sits among Subdecay tremolos
The Vagabond was Subdecay's first tremolo3. Players looking for pattern-based tremolo rather than the Vagabond's two vintage amp styles can look at the Subdecay TremCoder and TremCoder 2, which take a sequencer approach to the effect instead.

Questions
Is the Subdecay Vagabond true bypass?
Yes. The Vagabond Tremolo uses true bypass switching, so when the effect is off your signal passes through without the pedal loading it down. Gearnews noted that unlike a lot of older tremolo pedals it won't suck your tone when not engaged.
Can the Vagabond Tremolo run at 18 volts?
Yes. Subdecay lists the Vagabond for both 9-volt and 18-volt operation with a standard DC input, so it works on a normal 9V pedalboard supply or an 18V supply if you want the higher headroom.
What is the difference between bias and harmonic tremolo?
Bias tremolo, like some Fender Blackface amps, creates subtle distortions and alters the frequency response while modulating volume. Harmonic tremolo, closer to older Fender Brownface amps, is a crossfade between high and low-pass filters, and because of the phase shift in the filters it often sounds closer to a vibrato or phaser than a tremolo.
How does the drift knob on the Vagabond work?
The drift knob is an envelope speed control. It lets your pick attack either slow down or speed up the tremolo, so the effect responds to how hard you play rather than running at one fixed rate.
What is a B-stock Vagabond Tremolo?
A B-stock unit is a blemished pedal: fully functional, with blemishes that may include paint scratches, silk screen errors, older style graphics or superficial damage. B-stock Vagabonds carried a $149 price instead of $169, include Subdecay's standard 3 year warranty, and all blemished pedal sales are final.
