The Alexander Pedals Jubilee Silver Overdrive is an overdrive pedal from Alexander Pedals built around one specific target: the Marshall 2555SL Jubilee 100W amp, the Silver Jubilee head associated with Slash1. Rather than a general-purpose dirt box, it is an "amplifier in a box" style pedal, voiced to behave like a cranked British amp rather than a stompbox clipping stage1.
According to the build documentation published by GuitarPCB, the circuit "captures the sound and feel of the legendary Marshall 2555 Silver Jubilee amplifier" and delivers "everything from articulate low-gain crunch to rich, saturated British overdrive with the dynamic response and harmonic depth of a cranked Jubilee head" at pedal volumes2. It lists for $189.99 USD on Alexander Pedals' own page3.
What it does to your sound
The Jubilee Silver is an overdrive "created with a specific sound in mind," and Pedal of the Day's reviewer found that "it achieves that sound with precision and authenticity"1. The reviewer's framing is that of a player chasing an amp rather than a generic drive color: "one that is both based on and sounds like an amplifier is right up our alley"1.
In practice that means the pedal is aimed at the Silver Jubilee's range, from low-gain crunch through saturated British overdrive, with the dynamic response of a loud amp head rather than the flatter feel of a simple clipping pedal2. The EQ is a passive three-band stack, the same architecture a British amplifier uses, so the Treble, Middle and Bass controls interact the way an amp's front panel does rather than acting as independent boost and cut bands31.
The controls
Alexander Pedals describes the front panel as five knobs3:
| Control | What it does |
|---|---|
| Loudness | Sets the output level of the pedal3 |
| Drive | Adjusts the gain and distortion3 |
| Treble | Part of the passive three-band tone stack, voiced like a British amplifier3 |
| Middle | Part of the passive three-band tone stack3 |
| Bass | Part of the passive three-band tone stack3 |
Pedal of the Day's walkthrough matches: Drive sets the gain and distortion, Loudness sets the output volume, and the three EQ knobs form the passive tone stack1.
Power and setup
The Jubilee requires a DC power supply with a 2.1mm pin, center negative, and it does not use a battery3. It will operate on supply voltages up to 18V, so an 18V output on a pedalboard supply is within spec3.
No battery option means this pedal needs a power supply from day one. Any standard center-negative 2.1mm adapter or isolated supply output works, and higher voltages up to 18V are supported by the maker3.
History and versions
The Jubilee Silver Overdrive was introduced on 28 December 2015, alongside Alexander Pedals' La Calavera phaser. Premier Guitar reported at the time that it is "a faithful reissue of the original Jubilee pedal," returning in "a pedalboard-friendly enclosure, soft-touch switching, and all the grind and crunch you could want"4. The original Jubilee was a Pharaoh Amplifiers pedal, so the Silver version is the second coming of that circuit in Alexander's lineup4.
The pedal got a full feature review from Pedal of the Day on 23 June 2019, which is where most of the published commentary on it comes from1.
DIY versions
There are two separate DIY routes for players who want a Jubilee-style circuit of their own:
- GuitarPCB bonus PCB. In October 2025, GuitarPCB published a build document for a bonus PCB based on the Alexander Jubilee Silver, describing the circuit as capturing the sound and feel of the Marshall 2555 Silver Jubilee amplifier2.
- One Control LWP Series Jubilee Red. A solder-free pedal kit for building an Amplifier In A Box (AIAB) pedal, assembled with a Phillips screwdriver and the included tools, which One Control describes as suitable for beginners. It lists at $89.99 USD and is not compatible with battery power5. This is One Control's own Jubilee-style circuit, not a kit of the Alexander pedal.
How it compares
The most direct comparison in the current market is the Wampler Golden Jubilee, another pedal built around the Silver Jubilee amp sound. Wampler lists it in the distortion/overdrive category6, and MusicRadar notes it can run at 9V or 19V from a pedalboard supply7, where the Alexander takes up to 18V3. Guitar World's reviewer went as far as to say of the Wampler that "it may be the best-looking pedal in Wampler's lineup"8. Both pedals chase the same amp; the Alexander is the older design, dating to the 2015 reissue4.
For context, Marshall itself has a long history in pedals, with earlier entries including The Guv'nor and Drive Master, plus small silver pedals from the early 2000s, as Guitar World has recounted9.

Questions
Is the Alexander Jubilee Silver a Marshall 2555 in a box?
It is built around the sound of the Marshall 2555SL Jubilee 100W amp, the amp associated with Slash. Pedal of the Day describes it as an overdrive based on and voiced like a British amplifier, and the maker's own description says it captures the sound and feel of the Marshall 2555 Silver Jubilee.
Does the Alexander Jubilee take a battery?
No. Alexander Pedals states that the Jubilee does not use a battery and requires a DC power supply with a 2.1mm pin, center negative. You will need a pedalboard power supply or a standalone 9V-style adapter to run it.
Can I run the Alexander Jubilee Silver at 18 volts?
Yes. Alexander Pedals says the Jubilee will operate on power supply voltages up to 18V, so an 18V-capable supply is fine. It still needs the standard 2.1mm center negative connector.
Is the Alexander Jubilee EQ active or passive?
The Treble, Middle and Bass controls form a passive three-band tone stack, voiced like a British amplifier. That is the same general approach a classic amp's EQ uses, rather than an active EQ that boosts and cuts with its own gain stage.
Is there a DIY kit of the Alexander Jubilee Silver?
There is DIY circuitry available. GuitarPCB published a build document in October 2025 for a bonus PCB based on the Alexander Jubilee Silver. Separately, One Control sells the LWP Series Jubilee Red, a solder-free Amplifier In A Box kit at $89.99 USD, though that kit is its own Jubilee-style circuit rather than a copy of the Alexander pedal.
