"This HR-16 features custom paint job and some great additional features. The drum machine itself has been fully refurbished and cleaned, the paint job is a piece by James Gramling with reverse black and white buttons with custom Letracet and abstract work on panel assemble all clear-coated for durability. The internal LEDs have been changed to blue and the spots were the original volume and data faders were located are backlight with ultra-violet LEDs. The volume and data controls have been relocated to the top panel assembly. Additional modifications include Master pitch control which ranges from above to WAY below original pitch for some truely unique sounds. We have also added a 12 position rotary switch which activates a variety of circuit-bent effects depending on position and pitch level. This is a one-of-a-kind modification and painting, functional art at its best."
