TONE MATCHER · SERIES 1
● A Delta Metrics machine
You search a song. We translate the artist's actual amp settings to your rig — your amp, your pickups, your guitar — and tell you how to play it.
THE METHOD
Pick from a hand-curated catalog of 25+ tones, or type any song we haven't seen yet. The search is fast and forgiving.
A deterministic rule engine compensates for amp voicing, pickup output and body type. No "AI feel" — just math you can audit.
Get six knob settings and one short playing tip — pickup position, attack, where the dynamics live. Ready in seconds.
THE CATALOG · 25+ ENTRIES
Hand-curated from rig rundowns and the long history of guitar magazines. Each tone is tagged with the source amp and pickup, then translated to whatever you've got plugged in.
Jimi Hendrix · 1967
"Neck pickup, light overdrive; let chords ring and use the volume knob for dynamics."
AC/DC · 1980
"Bridge humbucker, mid-forward Marshall crunch. Pick hand does the work."
Metallica · 1991
"Scooped mids, bridge humbucker, tight palm mutes. Gain lower than you'd think."
U2 · 1987
"Chime with a dotted-eighth delay in front. The tone is 50% the delay setting."
Pink Floyd · 1979
"Big Muff into the front; sing each bend. Vibrato is the voice."
Stevie Ray Vaughan · 1983
"Clean with hair. Dig in hard — the dynamics come from your hands, not the amp."

Open catalog →CAN'T FIND IT? · 03
Type any song and artist. The app reaches into rig rundowns, interviews, forum threads, and dusty corners of the web; an LLM extracts the actual rig and settings; the rule engine translates it to your gear.
No vibes. No "approximated." You get the source amp, the source pickup, six knob positions, and links to every web page it pulled from. Audit it yourself.

FIELD REPORTS · UNEDITED
Submitted unsolicited. We took out the typos. The opinions are theirs. Each report includes the player's gear chain.
"Wife came in and said 'oh god not that song again.' That's the metric I use."
Asked it for the Pride and Joy thing. It knew SRV ran a Vibroverb, dropped my treble two notches, told me to dig in. Sounded right inside ten seconds.
"Came out closer than I'd ever gotten by ear."
Looked up Layla. App pulled the Champ + Tube Screamer thing and translated it to my Mesa. The note about pushing the front end is what actually nailed it.
"First time a software has understood what an AC15 already wants to do."
I bought this for the U2 settings and stayed for the Beatles ones. The chime is right. Not 'close enough' right — actually right.
"Engineer told me to leave it alone."
Half my gigs are 'play it like the record.' This cuts rehearsal in half. Asked for Sultans, got the Strat-position-4 trick translated to my Tele.
"Eight years of trying. Eight."
Enter Sandman, scooped mids, bridge bucker, gain lower than I'd ever set it. Followed it. Drummer said it sounded like the record finally.
"Pulled from a 2009 forum post I'd never have found."
Generated a tone for a song nobody's covered. That's the moment I stopped being skeptical. Friedman doesn't have the Hiwatt voice — the app knew that and worked around it.
