Compact analog boost for pedalboards
The Rowin LEF-318 is a mini-sized booster pedal built with a full metal case for guitarists who need a clean volume lift without adding bulk. Its discrete analog circuit provides up to 20 dB of pure gain while preserving the instrument's core tone. True bypass switching ensures the signal path remains untouched when the effect is disengaged. This unit suits players wanting a transparent level increase for solos or driving a tube amp harder.
Replaces weak or noisy volume pedals
Swapping a passive volume pedal or a low-headroom boost for this unit removes signal loss and adds 20 dB of clean gain with active 15 dB bass and treble controls. The jump is worth it when your current setup cannot push the front end of an amplifier without adding hiss or coloring the midrange. It also solves the problem of a crowded board where a standard-sized pedal will not fit. The 1 mOhm input and 100 kOhm output impedances match typical guitar and amp interfaces.
Fits tight boards and needs external power
Measuring 12 cm in packaged length, the mini enclosure leaves room for other effects while the all-metal chassis withstands stage use. A 9 V DC negative-centre supply is mandatory because the pedal cannot run on batteries and draws 26 mA. The four-knob layout (Gain, Treble, Bass, Volume) lets you shape the boosted signal before it hits the next pedal or amp input. Builders who need battery operation or a larger footprint should look elsewhere.

Questions about this item
What are the dimensions of the LEF-318 pedal so I can plan pedalboard space?
The unit measures 12 by 6 by 5 centimetres including its packaging. The all-metal mini chassis fits tight board layouts.
How do I power the LEF-318 and what is the common wiring mistake?
Connect a 9 V DC supply with a negative-centre barrel plug; the pedal cannot run on batteries. Reversing the polarity will prevent operation.
When should I check the footswitch or jacks on the LEF-318 for wear?
The true-bypass footswitch and 1/4-inch jacks are rated for long life; inspect them if you hear crackling or the bypass signal drops.
