The Blammo! Utility Boost is a dual stage boost pedal from Blammo Electronics, packing two distinct boost circuits into one compact enclosure: a cocked wah boost and a flat amplified boost, plus a buffer that works even when the pedal is bypassed1. It sits in the wider field of boost pedals as a utility tool: as Delicious Audio's Paolo De Gregorio put it, it covers everything "from transparent level boosts to vintage-style mid pushes, without complicating the interface"2.
Two boost circuits in one box
The pedal carries two separate circuits. The Cocked Wah Boost is a mid-focused boost whose Frequency knob simulates the action of stepping on an actual wah pedal by setting the accentuated frequency point: left for the brightest tones, right for more bass and heel-heavy sounds1. Delicious Audio describes this as a sweepable mid-focus, a heel-toe wah simulation2. Players who want that sound without carrying a wah pedal get it from a single knob.
The Flat Boost side is an opamp-based linear boost, set louder than the cocked wah circuit1. Delicious Audio describes it as an op-amp-driven clean lift with an internal trim pot for gain matching2, so the two channels can be balanced against each other inside the pedal.
Controls
| Control | What it does |
|---|---|
| Volume / Master Output | Unified output level for both channels3 |
| Frequency | Heel > Toe, sets the accentuated frequency of the Cocked Wah3 |
| Bypass | Selects Buffered or True bypass3 |
| Channel footswitch | Selects Flat Boost or Cocked Wah3 |
The footswitches are relay-based with no-click switching: CHANNEL selects the boost type, and ON/OFF engages the effect2.
Buffered or true bypass
A bypass switch selects between Buffered and True bypass3, and the buffer is switchable onboard3. The buffer option is based on the popular Klon Centaur circuit, according to Blammo Electronics1, and Delicious Audio describes it as a Klon-derived buffer with an always-on option that keeps working even in bypass, for signal integrity in long chains2. Players building large boards will recognize this as the job a dedicated buffer pedal usually does; here it is built in.
"The buffered bypass alone makes it a pedalboard workhorse, especially for players combating tone loss in complex setups."
Construction
Delicious Audio describes a hybrid construction: an SMD/through-hole design with Panasonic capacitors for cost-effective durability2. The jacks are top mounted1, which keeps the pedal's footprint narrow on a board.
What reviewers said
Guitar Pedal X's Stefan Karlsson, writing in August 2025, listed the Utility Boost at $149.99 with Flat Boost or Cocked Wah channels, Frequency control, Buffered/True bypass and top-mounted jacks, and framed it alongside the Mile End Effects Pique as a type of smart boost3. His verdict on the cocked wah side was warm:
"I love the Cocked Wah side on this one. I'm a big fan of Mick 'Ronno' Ronson - and this would certainly help me to get my early Bowie / Ziggy Stardust on."

Questions
What is the difference between the Cocked Wah and Flat Boost channels on the Blammo Utility Boost?
The Cocked Wah channel is a mid-focused boost whose Frequency knob simulates stepping on a real wah pedal, setting the accentuated frequency point: turn it left for the brightest tones, right for more bass-heavy, heel-down sounds. The Flat Boost channel is an opamp-based linear boost with no filter character, and the maker sets it louder than the cocked wah circuit. A channel footswitch selects between them.
Does the Blammo Utility Boost have true bypass?
Yes, and buffered bypass too. A bypass switch selects between Buffered and True bypass, and the onboard buffer can be set as an always-on option that keeps working even when the effect is bypassed, which Delicious Audio's Paolo De Gregorio describes as a way of preserving signal integrity in long pedal chains.
Is the buffer in the Blammo Utility Boost based on the Klon?
Yes. Blammo Electronics states on its product page that the buffer option is based on the popular Klon Centaur circuit. Delicious Audio likewise describes it as a Klon-derived buffer with an always-on option, even in bypass, for signal integrity in long chains.
Where are the jacks on the Blammo Utility Boost?
The jacks are top mounted, according to Blammo Electronics' product page. That layout suits tight pedalboards, since cables enter and leave from the top edge rather than the sides.
Do both channels share one volume control?
Yes. Delicious Audio describes a shared volume control giving a unified output level for both channels, so one knob sets the master output whether you are on the Cocked Wah or the Flat Boost side. The flat boost side is set louder than the cocked wah circuit by design.
