I would say this is in mint condition. Includes the Tone King MKII Preamp Module and user guide, as well as the original box and packaging. Requires the Synergy SYN-2 Dual Module Tube Preamp (not included). Currently available in one of my other ads.

As described on the Synergy Amps product page:

For nearly two decades, Tone King has been synonymous with premium American tube tone, and no amplifier better defines their legacy than the Imperial MKII. From the glassy spank of vintage Blackface cleans to the gritty breakup of the best Tweed tones, the Imperial delivers the touch-sensitive dynamics and sweet harmonic complexity that have made Tone King a revered name among boutique amp aficionados. Now, through a collaboration with Synergy, the Tone King Imperial experience has been brought to the groundbreaking modular preamp format.

The Imperial module mirrors the two-channel design of the flagship Imperial MKII amplifier, offering independent Rhythm and Lead channels, complete with intuitive controls and the unmistakable feel of a handwired American classic. With a powerful, dynamic voice and inspiring responsiveness, the Tone King Imperial module puts decades of vintage tone at your fingertips – now with all the flexibility of the Synergy platform.
