01Valeton GP-50 (TS / Green OD Block)
Run into Katana front input as clean boost/tightener with amp/cab models bypassed

The Katana 50 MkII uses the Brown amp type to emulate high-gain 5150/lead saturation, while presence is omitted since the 50-watt faceplate lacks a physical presence knob. The Valeton GP-50 acts as a classic TS-style front-end boost (zero drive, high level) to cut flubby sub-lows and push the Katana's preamp into tight slam territory. Active humbuckers on the ESP LTD MH-1000 provide strong attack, so amp gain is kept at 7 to prevent excess noise and mush.
