Pure Analog Compressor Pedal

The Rowin LEF-333 is an analog compressor effects pedal built for electric guitar players who want studio-grade sustain and level control. Its zinc-alloy mini enclosure measures 95mm by 45mm by 53mm and fits easily on a crowded board. True bypass switching keeps the signal path transparent when the effect is disengaged.

Two Modes And Three Knobs

A Normal/Treble toggle changes the compression character while Level, Comp and Tone knobs shape volume, intensity and EQ. An LED shows the active state. The package includes the pedal and a user manual; a 9V DC power supply is not included.

Check Power And Board Space

Verify your pedalboard can supply 9V DC with a centre-negative barrel plug and at least 12mA of available current. Confirm the 1/4-inch mono input and output jacks match your signal chain. The pedal weighs 273g with its box, so ensure the mounting method supports that mass.

Questions about this item

Will the 9 V DC power jack or the 1/4" mono jacks need replacement after heavy use?

The pedal draws 12 mA from a centre-negative 9 V supply; the metal-jacketed 1/4" input and output jacks and the DC jack are mounted on the zinc-alloy chassis, so they handle repeated plugging without board stress.

What limits how long I can keep the compressor engaged during a set?

Continuous operation is only constrained by the 12 mA current draw from your 9 V supply; there is no thermal shutdown or duty-cycle limit in the analogue circuit.

How much noise or heat does the unit add when it stays on all day?

The analogue compressor runs at 12 mA with no fan or digital clock, so it adds negligible hiss and the zinc-alloy case stays at ambient temperature even after hours of use.
