01Fuzz (owned) — used as treble booster substitute
Set fuzz gain LOW — you want boost and upper-mid push, not fuzzy saturation. Tone knob high to simulate treble booster's bright voicing. If your fuzz has a tone bypass or flat setting, use that with tone at 8.
The Blues Junior is darker and more scooped than a Vox AC30 Top Boost, which has a pronounced 2-3kHz peak. Compensate by pushing mids to 7 (vs AC30's flat mid control) and keeping treble moderate at 5 — the Fender treble shelf is higher than Vox and will get shrill if pushed. The FAT switch adds low-mid warmth that approximates AC30's Class A compression. Your Yamaha's ceramic humbuckers are hotter and darker than Tri-Sonics; the fuzz-as-boost with high tone setting pushes the necessary upper harmonics Brian got from his Rangemaster.
