Classic Overdrive Sound

The Rowin LEF-315 Dumbler is an analog overdrive pedal that simulates a vintage Dumble amplifier for electric guitar. Its compact mini enclosure houses a full metal case designed to save space on a pedalboard while delivering a classic overdrive tone ranging from light to medium low distortion.

Four-Control Tone Shaping

Shape your sound using independent gain, tone, voice and master volume dials. The voice control adds a crisp bite to adjust the colour of the overdrive, while the true bypass foot switch engages the effect smoothly without affecting the original guitar signal when disengaged.

Pedalboard Integration

The unit operates on a standard DC 9V negative centre power supply drawing 26mA. It presents a 1M ohm input impedance and a 100k ohm output impedance for compatibility with typical pedalboard signal chains. The sturdy metal construction ensures durability for stage and studio use.

Questions about this item

How much gain can I expect from the 315 model once it's on my pedalboard?

The LEF-315 delivers a vintage Dumble-style overdrive that ranges from a light, tasty breakup up to a juicy medium-low distortion, shaped by the gain, tone, voice and master volume controls.

What does the 470k ohm input impedance mean for my guitar signal?

The 470k ohm input presents a high-impedance load that preserves your pickup's natural tone and prevents signal loss when the pedal is first in the chain.

Will the 12 cm boxed footprint fit on a crowded board?

The mini-size metal enclosure measures 12 cm with packaging, so the pedal itself is even smaller, leaving plenty of room on a tight pedalboard.
