BLAMMO! TNYDUMBLE: An Affordable, Pedalboard-Friendly Take on a Highly Sought-After Circuit
As prices for modified Dumble-style pedals continue to climb on the second-hand market, many players are finding themselves priced out of a circuit they've long admired. Heavily modded NOTADUMBLE units now sell for nearly triple the cost of an original, and while DIY builds remain an option, they require time, tools, and confidence with a soldering iron.
BLAMMO! Electronics aims to change that with the TNYDUMBLE: a compact, pedalboard-friendly overdrive that delivers the most sought-after modifications straight from the factory. By separating the clean boost and overdrive circuits, adding an order switch, and refining the overall design for modern pedalboards, the TNYDUMBLE offers a practical and accessible way to experience a beloved Dumble-style circuit in 2025.

Circuit Design & Key Modifications
At the core of the TNYDUMBLE is a thoughtfully reworked version of the original Dumble-style circuit, redesigned to deliver the flexibility most players were seeking from the start. BLAMMO! Electronics separated the JFET-based clean boost and the overdrive into two independent circuits, allowing each side to be engaged on its own or combined for stacked tones without compromise.
An onboard order switch lets players choose whether the clean boost hits the overdrive or follows it, dramatically expanding the pedal's tonal range. This simple but powerful addition makes it easy to move from tight, punchy drive tones to more open, volume-forward boost applications. Alongside these changes, the core character of the circuit remains intact.
Overdrive Section
The overdrive side of the TNYDUMBLE remains faithful to the original circuit that made the design so popular, preserving its dynamic response and touch-sensitive feel. Built around asymmetrical MOSFET clipping, the drive delivers a smooth yet articulate breakup that responds naturally to picking dynamics and guitar volume changes.
An internal presence control allows players to fine-tune the high-end response of the overdrive, making it easy to adapt the pedal to different amps and guitars. From low-gain edge-of-breakup tones to richer, harmonically complex drive sounds, the TNYDUMBLE's overdrive section stays true to its roots while integrating seamlessly with the newly separated boost circuit.
Clean Boost Section
The TNYDUMBLE's clean boost is built around a JFET-based circuit designed to add clarity, punch, and headroom without masking the natural character of your guitar and amp. Unlike the original combined layout, this boost now operates as a fully independent section, making it just as useful on its own as it is when stacked with the overdrive.
A dedicated high-frequency tone control sits flat at noon, subtly enhancing the top end when turned clockwise or gently rolling it off when dialed back. This control works in tandem with the input knob, which simultaneously reduces low end and gain, allowing players to shape tighter, more focused boost tones or keep things full and open. The result is a clean side that feels flexible, musical, and highly responsive across a wide range of setups.
Conclusion
With the TNYDUMBLE, BLAMMO! Electronics delivers a timely answer to an increasingly expensive and inaccessible corner of the pedal market. By combining the most requested modifications, circuit separation, order switching, and soft-touch relay switching into a compact, ready-to-play format, the pedal removes the barriers that once stood between players and this sought-after Dumble-style sound.
Rather than reinventing the circuit, BLAMMO! focused on refining and modernizing it, preserving the tonal character that made the original design so appealing while adapting it for real-world pedalboards in 2025. For guitarists looking to capture classic Dumble-inspired tones without chasing rare or overpriced units, the TNYDUMBLE stands out as a practical and compelling option.
