Yakov Tsvirkunov

In this 2001 interview, Yakov says that he use a Mesa/Boogie Triaxis. It was seen between 2001-2011

GUITAR.RU Q: And what kind of effects chain do you have in concert now?

YAKOV TSVIRKUNOV: My guitar goes straight to TriAxis. My TriAxis uses a Korg PX3 Pandora as an effects processor, which is included in the loop. I use it when there is no normal processing on the remote control. If there is good processing on the remote, then the sound engineer controls the effects himself. I only use a small delay in Korg Pandora. Of course, Pandora is a low-end processor, but I plan to take Alesis Quadraverb and use it with TriAxis. Then I include TriAxis directly into the food processor (or into the "tip"). Personally, I prefer the Marshall JCM900, a hundred-watt combo amplifier, or its analogues in terms of power and quality. At the same time, the signal from the TriAxis line output goes to the remote control, is mixed, and the output produces a very rich sound at all frequencies.

Yakov Tsvirkunov used the Marshall JCM2000 Amp Head with Marshall cabinets during his live performances with the bands "Король и Шут" and "Северный флот" between 2003-2005 and 2010-2015, as evidenced by the image provided.
