Rowin LEF-300 series Compact / Miniature Case Size. That good classic rock sound with very low noise. An extra 2 way switch for normal or treble setting. Advances in circuitry design have made it possible for guitar effect pedals to be built in a compact enclosure that literally fit in the palm of your hand.
The compression of this pedal goes from subtle to smashed very quickly. Also the modes of “normal” and “treble” seem to be reversed from what the knob indicates. Still, if you need a clean boost with an EQ sweep, it’s a good pedal for the money.
The actual compression is hardly noticeable if even there. Turning up the compression control is more like a volume control that compression. The normal/treble toggle switch is backwards. The actual pedal is well built and quiet. It is more a volume boost than a compressor. It would be a good value and enjoyable if it actually functioned as intended.
