01Onboard Booster (T-Scream model)
Engage the Katana onboard Boost block to tighten the low end and replicate the TS9 front-end push
The Katana 50 MkII lacks a physical presence knob, so upper-mid aggression is achieved by pushing treble and mids on the Marshall-voiced Brown model. The onboard T-Scream boost tightens the Les Paul's passive humbuckers to match the hot attack of the original Gibson Flying V with an Invader pickup without muddying the low end. Keep reverb off to maintain the dry, raw tracking of Kill 'Em All.
