01HeadRush Prime: Orange Distortion (Boss DS-1 clone)
Primary gain source; keeps sustain long and singing

Set to roughly 380ms for spacious stereo tail
The HeadRush FRFR-108 is a flat-response powered cabinet, so all tone shaping is handled entirely inside the HeadRush Prime using a clean Mesa Mark II model. Because the Hohner MadCat had single-coil snap while the Ibanez RG3EX1 has hotter humbuckers, rolling guitar tone back to 8 and keeping the DS-1 Tone at 4 prevents brittle fizz while retaining high-mid cut. Double-gain prevention is preserved by leaving the simulated amp channel clean at gain 2 while the DS-1 block supplies the singing saturation. Clean verse: bypass the Orange Distortion block and leave the subtle flanger on.
