Compact Five-Band Graphic EQ

The Rowin LEF-317A is a mini-sized analogue equalizer pedal built for electric guitar. Its full metal housing measures 3.7 by 1.8 by 2.1 inches and weighs 8.6 ounces with the box. Five fixed bands at 100, 250, 630, 1.6k and 4k Hz each offer a ±18 dB gain range for precise tonal shaping.

Suited For

Guitarists who need surgical frequency control on a crowded pedalboard will appreciate the true-bypass switching and dedicated volume knob. Players requiring parametric sweep, more than five bands or battery operation should look elsewhere, as the unit only runs on an external DC 9 V centre-negative supply.

Build Integration

A single 1/4-inch mono input at 470 kΩ and output at 1 kΩ slot into any standard signal chain. The 8 mA current draw leaves ample headroom on typical pedalboard power supplies, while the compact aluminium chassis frees up board space for additional effects.

Questions about this item

What power supply must I already own to run the LEF-317A pedal?

A 9 V DC adapter with a negative-centre barrel plug that can deliver at least 500 mA. The pedal draws 26 mA.

Will the 100 kΩ output impedance work with my vintage amp that expects a high-impedance signal?

Yes. The 100 kΩ output is designed to feed standard guitar-amp inputs without loading them down.

How can I verify the true-bypass circuit is actually passing my dry signal when the pedal is off?

Disconnect the power supply; if your guitar tone reaches the amp unchanged, the true-bypass path is working.
