What every knob on a guitar amp actually does — in plain English — with sensible starting ranges and the mistakes that make a tone sound bad. Then dial in a real song and let the tool adapt it to your exact gear.

Low gain = clean and dynamic; high gain = saturated and compressed. The single biggest mistake players make is using too much gain: it sounds powerful in your bedroom, but it mushes up note definition and feedback gets uncontrollable.
Crucially, your pickups change the right gain: a hot humbucker drives the amp far harder than a single-coil, so the same record needs less gain on a Les Paul than on a Strat. (That compensation is exactly what GuitarToneAdapt calculates.)
Controls the low end — body and thump. Too much and the tone gets boomy, flubby and undefined, especially with high gain (palm mutes turn to mud). Too little and it sounds thin and brittle.
The most important knob on the amp. Midrange is where the guitar lives in a band mix and where your ear is most sensitive. Scooping mids (turning them down) makes a tone sound massive on its own — and then completely disappear the moment drums and bass come in.
Sets brightness and attack. Too much is harsh and fizzy; too little is dull and muffled. Treble interacts heavily with your guitar: single-coils and maple necks are already bright, so they need less treble than a dark mahogany humbucker guitar.
Presence boosts the very top high frequencies in the amp's power amp — it adds air, bite and "cut" that treble alone doesn't. It's the knob that makes a lead jump out of a mix. Too much = ice-pick harshness and fizz; too little = the tone feels boxed-in and dull.
Adds space and depth — like the room the amp is in. A little goes a long way: surf and clean tones use a lot, high-gain rhythm uses very little (reverb smears fast palm mutes). Set to taste; it doesn't change the core voice of the amp.
Every "best amp settings" chart assumes a specific guitar, pickups and amp — usually the one on the original record. Copy those numbers onto different gear and it sounds wrong, because pickup output, body wood and amp voicing all shift where the knobs should sit. That's the whole problem GuitarToneAdapt solves: pick a song, tell it your rig, and it re-dials the settings for what you actually own — free.
