MK-ULTRA 35w Head

MK-ULTRA 35w Head

Our compact MK-ULTRA heads draw inspiration from 60s American blackface series amplifiers with a twist. They are voiced for shimmering mids and overdrive. The cleans chime and sing with a silky body and segues into overdrive seamlessly. 6L6 power and bottom. Switches on the front panel include Bright and Deep. Bright adds subtle top end sparkle and Deep considerably increases gain across the whole guitar frequency range. Leads have never been more harmonically complex in the Deep setting. Headroom becomes nil and the touch sensitivity will make the MK-ULTRA a mainstay of your rig. The dynamic ability must be experienced firsthand. Well rounded response, character and bloom all receive high marks from this series of amps.


We designed our large output transformers specifically for this series of amps and they have made their way into other builds of ours with excellent results. A superior output transformer cannot be overlooked. It is the soul of the amplifier. Ours are made by Pacific Transformer in Anaheim, California.


Our custom made, hybrid design printed circuit boards are also made in California. We specifically designated the power supply terminations as the only through-hole design and use eyelets soldered into place for the remainder, effectively keeping the entire preamp handwired, much like any blackface amp, but with the time and space saving advantages of PCB traces that are limited only to the high voltage power supply.
