The Beekeeper is a hand-built guitar preamp in a pedal, featuring two vacuum tubes running at high voltage.

Its design is inspired by the famous ODS circuit, usually associated with the signature sound of many legendary guitar players. As a result, Beekeeper is having a sparkling clean tone, which is gradually pushed into a smooth, rich and touch-sensitive overdrive as you crank up the gain.

Technical Details:

The Beekeeper operates off a standard 12VDC voltage, which is boosted inside the pedal to the proper high voltage for the best performance of the vacuum tubes.

To keep the guitar signal unaffected when the preamp is not engaged the switching is done using a true bypass circuit.

The preamp is featuring two stacked channels: Clean and OD. The clean channel consists of two vacuum tube gain stages.

The EQ and the toggle switches are located right after the first gain stage, so they are affecting both Clean and OD channels at the same time. Engaging the OD channel will add two more gain stages after the clean channel. In this mode both Clean volume and OD volume controls are active, providing total control over the tone and the amount of overdrive.

As the tube preamp consumes much more current comparing to the regular effect pedals, Beekeeper comes with a high-quality wall-mount power supply.
