Rowin LEF-323 Greenizer Overdrive Pedal

The Rowin LEF-323 Greenizer is an analog overdrive pedal built for guitarists who want a compact TS808-style circuit on their board. Its full metal casing houses a true bypass switch that keeps the signal path clean when the effect is disengaged. The pedal draws 26mA from a standard DC 9V centre-negative supply. It suits players seeking a boutique-style drive in a mini enclosure.

Capacity and Headroom

Three control knobs adjust volume, tone and gain, while a mode switch toggles between boost and normal settings for flexible drive character. The 1M ohm input and 100k ohm output impedances match typical guitar and amplifier stages. A BBD chip with static filtering shapes the overdrive texture without digital processing. The circuit delivers a thick, full tone that retains low-end body when pushed.

Pedalboard Integration

Measuring 12/6/5 cm with its box, the mini footprint saves valuable pedalboard space for other effects. The 1/4-inch mono input and output jacks connect directly to standard instrument cables. True bypass circuitry ensures the pedal disappears from the signal chain when off, freeing up tonal clarity for the rest of the rig. It operates with common Boss-style or One Spot power adapters.

Questions about this item

Will the Rowin LEF-323 Greenizer work with my existing 9 V centre-negative power supply?

Yes, it uses a standard Boss-style DC 9 V centre-negative adapter; One Spot and Power-All supplies also work.

How can I confirm the true-bypass switching is functioning after I connect it?

With the pedal off, your guitar signal passes straight from input to output with no tone loss; engage the footswitch and the overdrive circuit activates.

Does the Greenizer include a power adapter or patch cables in the box?

No, only the pedal itself is supplied; a 9 V centre-negative adapter and 1/4″ mono cables must be purchased separately.
