All Right Now amp settings — Boss Katana 100w 2×12 gen3

The Free guitar tone for “All Right Now”, dialed in for a Boss Katana 100w 2×12 gen3 with a Gibson Slash 4. Studio version, Fire and Water (1970)

Original rig

1959 Gibson Les Paul Standard with PAF humbuckers → Marshall Plexi 50-100W cranked to natural breakup, no pedals

Thick, mid-forward crunch with vocal sustain and creamy breakup — not fuzzy, not clean, right in the sweet spot of tube saturation

Why these settings

Katana's Crunch channel emulates JCM800-era Marshall — close to Plexi territory. Mid pushed to 7 to capture Kossoff's vocal midrange honk. Treble dropped to 5 (vs original 6) because Katana's digital treble can get brittle where a real Plexi stays smooth. Gain at 6 gives that 'cranked but not fuzzy' breakup zone. Reverb at 0 — the original is bone dry except for room ambience baked into the recording.

PRO TIPKossoff's secret weapon was his slow, wide finger vibrato and constant use of the guitar's volume knob — roll back to 6-7 for the cleaner rhythm chords, full up for the solo. The tone lives in your hands more than the amp. For the intro chord, fret the high E and B strings at the 5th fret while playing the open A shape to get that shimmering ring.
