The Tesseract Boost/Preamp is a clone of the TC Electronic Integrated Preamp, which was popularized by Meshuggah in the 1990s. It is designed to connect directly to your guitar and features a boost and EQ. The original unit could run on either a 32V external supply or a standard 9V battery. However, since 32V supplies are hard to find, the Tesseract Boost/Preamp includes an on-board charge pump that allows it to operate at 32V using a standard 9V supply.

The only modification made to the original design is the removal of a pop-suppression circuit at the input. This circuit was designed to prevent a loud pop when the input jack is first plugged in, but it is not necessary in a pedal format. Its removal does not affect the tone or functionality of the Tesseract Boost/Preamp.
