The [Blammo! Electronics Blues Blaster] is a hand-made drive pedal from Portland, Oregon, built around the circuit of the Marshall Blues Breaker amplifier. BLAMMO! Electronics describes it as delivering "MARSHALL DRIVE AND DISTORTION TONES", with two modes: a STOCK mode that keeps "that vintage low-gain bell like tone of the original circuit" and a MOD mode with "a higher gain distortion sound"1. It sits in the same family as other overdrive pedals and distortion pedals built on the Blues Breaker lineage.
The pushbutton gain switch
The pedal's centerpiece, as Delicious Audio's Paolo De Gregorio put it, is "a miniature pushbutton switch that kicks the gain into high gear". With the button engaged, he found it "puts the Blues Blaster well into distortion territory [...] highlighting its penchant for effortlessly summoning sweet, musical feedback"2. In practice that gives a player two pedals in one box: the low-gain Blues Breaker voice under the foot, and a momentary or latched boost into full distortion on demand.
"Its centerpiece is a miniature pushbutton switch that kicks the gain into high gear"
Where the circuit comes from
BLAMMO! Electronics says the pedal is "based on (and named after) the Marshall Blues Breaker amplifier"1. Origin Effects, writing about their own Blues Breaker-style designs, explains the amp's place in the Marshall line: "The Blues Breaker is based on the Marshall Blues Breaker amp, of course: the combo version of the JTM45"3. The Blues Blaster is a hand-made evolution of that circuit rather than a straight clone, adding the MOD mode, the pushbutton, and a discrete buffer at the end of the circuit "to ensure it stacks well / plays nicely with other pedals"1.
Controls and hardware
| Feature | Detail |
|---|---|
| Modes | STOCK (original low-gain circuit) and MOD (higher gain distortion)1 |
| Gain switch | Miniature pushbutton that kicks the gain into high gear2 |
| Bypass | No-click relay-based true bypass, momentary or latching (tap or press and release)1 |
| Buffer | Discrete buffer at the circuit's end for stacking with other pedals1 |
| Capacitors | Panasonic film capacitors1 |
| Enclosure | 125b with top-mounted jacks1 |
The top-mounted jacks make the pedal friendlier on crowded boards, since cables exit upward rather than sideways1.
Power
The Blues Blaster accepts "the standard 2.1mm center negative 9 volt DC adapter" and draws 36 mA1. That current draw is modest but worth noting: it is above what many daisy-chain outputs on older supplies comfortably share, so a dedicated outlet on an isolated supply is the safe assumption.
The pedal has no battery option listed; it runs only from a 9V DC center negative adapter1.
On bass and guitar
Delicious Audio's demo put the pedal through its paces on both instruments: "In this demo, I take the Blues Blaster for a spin on both bass and guitar in a mutant punk blues jam", followed by a run through the full control set2. Players curious about Blues Breaker-style drive on bass can hear it in that demo before deciding how it fits alongside dedicated bass pedals.
Availability and price
BLAMMO! Electronics lists the Blues Blaster at $154.99 on its product page (as of 25 October 2026)1. When Delicious Audio first covered the pedal in December 2023, it was a pre-release prototype: "It doesn't look like this new hand-made Blues Breaker evolution by the dudes at Blammo! Electronics is officially out yet"2. The pedal is now on the maker's own product page, hand-built in Portland, Oregon1.
BLAMMO! Electronics also builds other hand-made drives, such as the Deth Pedal, a limited collaboration with Dirty Haggard, and the Shrew.

Questions
What amplifier is the Blues Blaster based on?
BLAMMO! Electronics says the pedal is based on, and named after, the Marshall Blues Breaker amplifier. Origin Effects adds that the Blues Breaker amp is the combo version of the JTM45. The pedal is a hand-made evolution of that circuit rather than a straight copy, with a stock mode that keeps the original's low-gain character and a mod mode that pushes into higher gain distortion.
Is the Blues Blaster true bypass?
Yes. The pedal uses a no-click, relay-based true bypass system with soft switching that can work as momentary or latching, so you can either tap the switch or press and release it. BLAMMO! Electronics describes this as an update to the footswitch on the original design.
Does the Blues Blaster work with bass?
Paolo De Gregorio at Delicious Audio demonstrated the pedal on both bass and guitar in a video demo, playing a mutant punk blues jam and then running through the full control set. The pedal is aimed at Marshall-style drive and distortion tones, and the demo shows it holding up on bass as well as six strings.
What power supply does the Blues Blaster need?
The Blues Blaster accepts a standard 2.1mm center negative 9 volt DC adapter and draws 36 mA. It has no battery option listed, so plan your pedalboard power accordingly.
Where is the Blues Blaster made?
BLAMMO! Electronics builds the Blues Blaster by hand in Portland, Oregon. The pedal uses Panasonic film capacitors and comes in a 125b enclosure with top-mounted jacks.
