Rowin LEF-328 Tube Pusher Overdrive Guitar Pedal

Mini tube-like overdrive pedal

The Rowin LEF-328 Tube Pusher is an analog overdrive pedal built for guitarists who want classic tube-style saturation in a mini metal enclosure. It delivers ultra-wide dynamic range through two distinct working modes. BOOST mode raises the bottom end and adds a slight high-mid peak around 3.5KHz as drive increases. NORMAL mode colours the original signal very little, making it suitable for clean boosting.

Low current draw and true bypass switching

The pedal draws 40 mA from a standard DC 9V negative-centre adapter and presents a 1M Ohm input impedance with a 470 Ohm output impedance. True bypass switching removes the circuit entirely from the signal chain when disengaged, preserving core tone. The full metal shell provides shielding and durability for stage or studio use without adding noise or power overhead.

Compact footprint for tight pedalboards

Measuring 93.5 mm deep by 42 mm wide by 52 mm high and weighing 300 g, the unit fits into crowded board layouts where larger drives cannot. The 1/4 inch monaural input and output jacks use standard spacing for simple patch-cable routing. Builders who need multiple gain stages or stereo routing will need additional pedals, as this model provides a single mono channel only.
