Honza "Kirk" Běhunek has been one of the first guitar players in the world to use seven string guitars - and this is where the band name "Seven" comes from. Today, dropped tunings and seven (or even eight) string guitars define the modern guitar music.

Having been the most acknowledged progressive metal guitarist in the Czech Republic for a very long time, Honza K. Běhunek is definitely the most competent person to talk about hi-gain tube amplifiers. After a few years of intense cooperation, we decided to build his own signature amp and here it is: a non-compromising, pretty straightforward hi-gain monster.

No clean channel, no unnecessary knobs or switches; just two crushing hi-gain channels and a power amp section designed to deliver an incredible amount of tight bass at any volume. Rock-solid construction, simple design and ergonomics. That's it.


Two Hi-gain Channels with separate Gain, Bass, Middle, Treble, Presence and Master Volume Controls. The channels' signal paths are completely independent so that you can use different preamp tubes for each of the channels

Channel 1 (Red):
Singing lead tone with a little bit of vintage flavour. Performs great at any situation where fast attack and maximum articulation are desired. Perfect for fast solos that cut through the mix like nothing else.

Channel 2 (Blue):
The second channel is designed to comply with the heaviest of riffs: an agressive modern hi-gain with thunderous bottom that annihilates anything in front of it.

All-tube FX Loop with Adjustable Send Level

Output Volume Control sets overall volume after the fx loop.

Footswitch Pedal with red / blue indicator light


Preamp: 6x ECC83 (12AX7)

Poweramp: 1x ECC83 (12AX7) , 4x EL34 / 100W
(optionally 6550 or KT88, up to 150W)

Note: All 7 (!) ECC83 (12AX7) tubes are DC-heated for superior hum-free performance at any gain setting.

Output Impedance: 4 (2x8) / 8 (2x16) / 16 Ohm

Dimensions (W/D/H): 700mm x 260mm x 260mm
