Rowin LEF-3805 Slow Hand Pedal
The Rowin LEF-3805 Slow Hand is a digital guitar effect pedal that mimics a violin-like swell by cutting off the attack of each note. It suits guitarists who want ambient volume-swell textures without using a volume knob. The mini enclosure fits easily on a crowded pedalboard. True bypass switching keeps the core tone transparent when the effect is off.
Practical limits of the 1/4 inch mono interface
The pedal accepts a high-impedance instrument signal at 470K Ohms and delivers a low-impedance output at 100 Ohms. This impedance match works well with standard guitar cables and amplifier inputs. True bypass means the signal passes straight through when disengaged, avoiding tone loss. The effect requires a DC 9 V centre-negative supply drawing 100 mA, so a dedicated pedalboard power brick is recommended.
Check your pedalboard power and space
Verify that your power supply provides a centre-negative DC 9 V plug with at least 100 mA available current; the adapter is not included. Measure 95 mm depth by 45 mm width by 48 mm height to confirm the mini chassis fits your board layout. Ensure you have two 1/4 inch mono cables for input and output connections. Buyers who need stereo operation or battery power will find this unit unsuitable.

How does the 470 K ohm input impedance affect my guitar signal?
The high-impedance 1/4" input loads pickups minimally, preserving high-end detail and dynamic response.
