Harley Benton Custom Line Acoustic Preamp

Yes, it is designed for any electrified acoustic instrument, including mandolins or ukuleles equipped with piezo pickups. The high input impedance ensures the signal remains clear and natural regardless of the instrument type.

No, the XLR DI output is passive and does not require phantom power from a mixing desk to function. You can connect it directly to a PA system or audio interface using a standard XLR cable.

The Shape switch applies a mid-frequency scoop, which is excellent for cutting through a dense mix or removing boxy, nasal tones from your instrument. It provides an instant tonal adjustment without needing to manually tweak the EQ knobs.

Yes, you can plug your playback device into the 3.5mm auxiliary line input and monitor both your instrument and the music through the headphone jack. This makes it a great tool for quiet practice sessions.

The phase switch is a standard tool for managing feedback by flipping the polarity of your signal. While it won't eliminate all feedback in every situation, it is highly effective at neutralizing the specific frequencies that cause howling in acoustic instruments.

Yes, it runs on a standard 9V DC adapter with a center-negative polarity, which is compatible with most common pedalboard power supplies. It also supports 9V battery operation if you prefer a cable-free setup.
