UltraPure System Overview

The UltraPure System starts with K&K’s acclaimed Pure Mini pickup, a passive bridge-plate transducer known for its warm, natural, and dynamic sound. This pickup is paired with a dedicated onboard preamp mounted at the soundhole, giving you convenient access to your core tone controls while keeping your guitar’s appearance clean and uncluttered.

This active configuration provides a strong, clear output that interfaces easily with amps, PAs, and recording setups, making it a great choice for gigging players and studio work alike.

Onboard UltraPure Preamp Features

The newly designed UltraPure Preamp offers flexible and musical tone shaping. It provides +/-20 dB control over bass/low, K&K’s proprietary wide-band midrange, and treble/high frequencies, allowing you to fine-tune your sound for different rooms, styles, and instruments. An internal gain trimmer lets you set the overall output level to match your rig.

A built-in phase switch is one of the most important tools for live amplification, helping you tame feedback and improve clarity on stage. The preamp also includes a convenient volume control and a low battery indicator so you always know when it’s time to swap the 9V battery.

Installation Details

The system includes an endpin jack for a clean, professional output connection and a Velcro-mounted 9V battery holder for secure placement and easy replacement. All controls are designed for soundhole access, so you can quickly adjust your sound without reaching for your amp or mixer.
