Introducing the all-tube combo amp "Imperial MK II," featuring two iconic sounds of classic American amps on the lead and rhythm channels, as well as tube-driven spring reverb and tremolo. The Imperial MK II is a model that has been brushed up from its predecessor, the Imperial, and developed as an amplifier with vintage tone, feel, and ease of use. The rhythm channel offers a vintage clean mid-1960s sound, while the lead channel offers a vintage 1950s tone, providing a wide range of sounds in one unit. The lead channel's unique tone-shaping circuit's Mid Bite control allows you to vary the amount of drive while adjusting the overall tone, focusing on the midrange. The preamp is equipped with three 12AX7 vacuum tubes, one 12AX7 vacuum tube and one 12AT7 vacuum tube for the reverb, and two 6V6 vacuum tubes for the power amplifier. Featuring an open-back design and a 12-inch Eminence custom speaker, it delivers a powerful sound that can be used on large stages despite its 20W (RMS) output. In addition, in case the volume is too loud when practicing at home, the unit has a built-in Ironman II attenuator with six optimized levels of adjustment, allowing you to reduce the volume to -36dB without changing the sound quality. Using the included two-button footswitch, you can switch between two channels and turn the tremolo on/off with your feet. The Imperial MK II is an amplifier with a luxurious retro design and great vintage tone.Output Power (RMS): 20W@8Ω(RMS) Output (Peak): 28W@8Ω(Peak), 16W@16Ω(Peak) Preamplifier tubes: 12AX7 x 4, 12AT7 x 1 Power tubes: 6V6 x 2 Rectifier tube: 5AR4 x 1 Front Panel Controls: Channel Selector Switch (Lead/Rhythm), Reverb [Lead Channel] Volume Control, Tone Control, Mid-Bite [Rhythm Channel] Volume, Treble, Bass [Tremolo] Speed, Depth Rear Panel Controls: Attenuation Control (0dB, -3dB, -9dB, -15dB, -24dB, -36dB), Power Switch, Mode Switch (Operate/Standby), Rhythm Channel Switch (Bypass/Enable), HF Comp Switch (Max/Normal) Power supply: 100VAC, 50/60Hz Speaker: Eminence custom-designed '33' (12-inch ceramic magnet speaker, 30W, 8Ω) Input/Output Terminals: Instrument Input, Footswitch, Speaker Out (8Ω or 16Ω) *Also used with built-in speaker Dimensions: H505 × W575 × D270mm (including protrusions) Weight: Approx. 19.0kg
