The Effectrode Fire Bottle is a magnetic pickup booster: a boost pedal that works on the resonant frequency, the gain and the tone of a guitar's sound, rather than simply lifting the signal. Effectrode describes it as the Fire Bottle Tube Boost Guitar Pedal, built in the UK by the company1. MusicRadar's review found a "broad palette of rich valve boost tones" in it, and summed the pedal up as "An interesting, good-sounding pedal that's ideal for expanding a single-coil-equipped guitar."2
A real tube inside a stompbox-sized pedal
The Fire Bottle is a valve-driven stompbox, part of what MusicRadar describes as Effectrode's ever-growing range of valve-driven pedals2. At its heart is the 6112 dual triode, a tiny "subminiature" valve that MusicRadar notes was once used as a proximity trigger in WW2 anti-aircraft shells2. Despite carrying a real tube, the pedal is just slightly larger than your average stompbox2.
Because of the voltages required to drive the valves, batteries are not up to the job, according to MusicRadar2. The pedal comes with its own 12-volt power supply2, so plan your board's power around it rather than assuming a standard pedal supply will do.
What it does to your sound
As a pickup booster, the Fire Bottle works on three aspects of the guitar's sound rather than just raising the level2:
| Aspect of the sound | What the Fire Bottle does with it |
|---|---|
| Resonant frequency | Shapes where the guitar's pickup resonance sits2 |
| Gain | Up to 30dB of gain available2 |
| Tone | Tone shaping drawn from old amp circuits23 |
MusicRadar's reviewer found that "The tone control provides an instant supply of increased Fender twang."2
Guitar World's review, covering Effectrode's related Blue Bottle booster, describes the same gain figure and tone circuit approach: "this has up to 30dB of gain available, but the tone control is basically a 1940s Fender Harvard amp tone control"3. Effectrode's Blue Bottle designs are covered separately on the Effectrode Blue Bottle and Effectrode Blue Bottle Inductorized Booster pages, and the limited-run Effectrode JV-1A Blue Bottle sits in the same family of tube boosters.
Build and where it is made
MusicRadar's review highlighted the pedal's practical side2:
- Rugged, all-steel chassis
- All connections on the rear edge, to maximize pedalboard space
- Slightly larger than an average stompbox despite carrying a real valve2
On where it is built, the two sources disagree. Effectrode's own product page states the Fire Bottle Tube Boost is "built in the UK by Effectrode"1. MusicRadar's review, on the other hand, says "Effectrode's pedals are built in the USA"2. Both are given here.
What reviewers said
"An interesting, good-sounding pedal that's ideal for expanding a single-coil-equipped guitar."
The same review found a "broad palette of rich valve boost tones" in the pedal, and called the tone control an instant supply of increased Fender twang2.

Questions
Does the Effectrode Fire Bottle use a real vacuum tube?
Yes. The Fire Bottle is a valve-driven pedal built around the 6112 dual triode, a tiny subminiature valve that MusicRadar notes was once used as a proximity trigger in WW2 anti-aircraft shells. Because the valves need high voltages to run, the pedal cannot run on a battery and comes with its own 12-volt power supply.
Can the Fire Bottle run on a battery?
No. MusicRadar's review explains that because of the voltages required to drive the valves, batteries are not up to the job. The pedal ships with a 12-volt power supply, so plan your pedalboard power around that rather than a battery or a standard 9V daisy chain.
How much gain does the Fire Bottle provide?
Up to 30dB of gain is available from the Gain knob, according to both MusicRadar and Guitar World's review. Alongside gain, the pedal works on the resonant frequency and the tone of the guitar's sound, which is why it is described as a pickup booster rather than a simple clean boost.
Where is the Effectrode Fire Bottle made?
Effectrode's own product page says the Fire Bottle Tube Boost is built in the UK by Effectrode. MusicRadar's review states that Effectrode's pedals are built in the USA, so the two sources disagree on this point.
What guitars suit a pickup booster like this?
MusicRadar's overall verdict calls the Fire Bottle an interesting, good-sounding pedal that is ideal for expanding a single-coil-equipped guitar. The tone control, which the review says provides an instant supply of increased Fender twang, points to the kind of single-coil tones it is aimed at.
