A guitar amp sim, right in your browser

Plug in your guitar or bass and play it through Melodic’s amp: 10 amps with their speaker cabinets, five pedals and 20 preset tones, or a tone you dial in yourself and save. You hear every knob the moment you turn it, in the menus, in every song and in every drill. It’s free, and there’s nothing to install.

Real footage, real sound The Amp screen, 1:11 of it. The riffs are Hear it: Melodic’s modelled guitar playing through the amp exactly as it’s set on screen. Press Hear it, or a chapter, for the sound.

The whole rig

Amp, speaker, pedals: your rig on one screen

The Amp screen lays your sound out the way it runs: your tones down the side, the amp head and its knobs, the speaker cabinet, and the pedalboard in signal order. Pick a tone and you hear it straight away. Turn anything and the tone is yours to keep.

  • 10 amps: six for guitar, from a glassy clean combo to three-stage high gain, with acoustic and nylon-string voicings among them, and four for bass.
  • Speaker cabinets: a 2×12 open back, a 4×12 closed back and a 4×10 for bass, plus steel-string and nylon-string bodies for the acoustic voicings.
  • Five pedals: compressor and drive in front of the amp; modulation, echo and reverb after it.
  • 20 preset tones to start from, and room for 60 of your own.
  • Level-matched. Every tone is measured and evened out as you dial it in, so switching tones doesn’t jump in volume.
  • No guitar handy? Hear it plays a riff through the amp: an arpeggio, chords, funk, a riff or a lead line, or a groove or a walking line on bass.

The amps

10 amps, the ones the songs use

Every amp here is one that Melodic’s songs are played through, built the way a real amp is: tube gain stages, a tone stack, a power amp that sags when you dig in, and a speaker cabinet. With every knob at 5 and the pedals off, you hear exactly the song’s tone. Pick an amp to see its faceplate.

The Clean amp in Melodic: a glassy combo that stays clean until you dig inThe Jazz amp in Melodic: dark and round, for chords and smooth linesThe Crunch amp in Melodic: classic rock grit through a closed-back 4×12The High Gain amp in Melodic: three stages of gain for heavy riffs and soaring solosThe Acoustic amp in Melodic: a steel-string’s body around your electricThe Nylon amp in Melodic: a classical guitar’s soft, woody warmthThe Bass amp for bass in Melodic: round and deep, with the clean DI blended inThe Pick Bass amp for bass in Melodic: punchy upper mids that cut through a bandThe Fretless amp for bass in Melodic: a singing, vocal middleThe Slap amp for bass in Melodic: scooped and snappy for slap and pop

Clean: a glassy combo that stays clean until you dig in. Tones built on it: Glass Clean, Shimmer, Funk Rhythm, Blues Breakup, Fuzz Box, Ambient Swells and Surf Spring.

The knobs

Six knobs, like the amp in your room

Each amp has the controls you’d find on a real one, from 0 to 10. Drag a knob up or down (hold Shift for fine moves), scroll over it or use the arrow keys, and double-click to put it back to 5. Point at a knob and the amp tells you what it does.

The Crunch amp’s faceplate in Melodic: Gain, Bass, Middle, Treble, Presence and Master
Gain
How hard the amp is pushed: low stays clean, high gets gritty and sustains. It adds grit, not volume.
Bass
The low end: more is fuller and bigger, less is tighter.
Middle
More cuts through a band; less sounds scooped and heavy.
Treble
The top end: more is brighter and sharper, less is warmer.
Presence
The very top, after the amp: bite and air.
Master
How loud the tone is. Gain sets the grit, Master the volume.

The acoustic and nylon-string voicings have no Gain knob: they stay clean.

The pedals

Five pedals, wired the way guitarists wire them

The compressor and the drive pedal go in front of the amp, where a drive pedal pushes it into grit. Modulation, echo and reverb come after it, as if they were in the amp’s effects loop, so the repeats and the room stay clear however hard the amp is driven. Stomp a footswitch to turn a pedal on; the arrows on a pedal change its kind.

Comp

A compressor: evens out loud and soft picking, so notes ring on. Sustain, Attack and Blend, which mixes the squeezed sound with your guitar as it comes in, so the pick keeps its bite.

Drive

Boost, Overdrive or Fuzz, pushing the amp into grit. Drive, Tone and Level. It runs at four times the sample rate, which keeps even a full-on fuzz free of harsh digital aliasing.

Mod

Chorus, Flanger, Phaser or Tremolo. The chorus, flanger and phaser sweep left and right a quarter-turn apart, for a wide stereo sound. Rate, Depth and Mix.

Echo

A delay whose repeats bounce between left and right, darkening and softening like tape. Time, Repeats and Mix.

Reverb

Spring, Plate or Hall: the room around your amp. Decay, in seconds, and Mix.

Preset tones

20 tones to start from

Melodic’s own tones cover the sounds songs ask for most: 14 for guitar and 6 for bass. Each plays a riff that suits it when you press Hear it, and each is only a starting point: turn a knob and it’s marked Edited, ready to save as yours.

The song’s tone

Sounds like the record, switched for you

Until you pick a tone, the amp is set to Song’s tone. You play through each song’s own amp, clean for a ballad, crunch for a rock riff, high gain for a metal part, and it switches when the part does. The drills work the same way, each with its own tone.

Want your own sound in a song? Open the amp from the pause menu, or from the start card when you’re learning a song. It slides in over the song, and every change is heard straight away. Pick Song’s tone again to go back.

  • One amp for guitar, one for bass. Each keeps its own tone, so a bass part plays through your bass amp.
  • Playing through your own rig? Flip the amp’s power switch off and your guitar plays as it comes in, for your own amp, modeler or pedals.

Bass amps

4 amps for bass

Bass players get amps of their own. Bass is round and deep, with the clean DI blended in. Pick Bass has punchy upper mids that cut through a band, Fretless a singing, vocal middle, and Slap is scooped and snappy for slap and pop. They play through a 4×10 bass cabinet (or a 4×12 or 2×12), with the same five pedals and 6 tones, from Round & Deep to Deep Dub.

Plug in

From your guitar to the amp

  1. Plug in

    A USB audio interface or a guitar-to-USB cable gives you the best sound and the least delay. The first-time setup finds your input and sets your levels.

  2. Open the amp

    It’s in the main menu and in Settings → Your guitar. In a song it’s in the pause menu, and on the start card when you’re learning a song.

  3. Pick a tone and play

    The song’s tone, one of Melodic’s or one of yours. No guitar to hand? Press Hear it.

  4. Make it yours

    Change the amp or the speaker, turn the knobs, stomp the pedals, then Save as new.

Keeping the delay down

  • The amp adds about half a millisecond. Nothing in it looks ahead, so you hear each note as you play it.
  • The rest is your setup. Your audio interface and browser add their own delay; the setup shows what your computer reports.
  • Wired headphones, not Bluetooth, which adds a delay you can hear.
  • A microphone is only played back once you tell Melodic you’re on headphones, so it can’t howl through your speakers.

Your own amp or pedals?

Switch Melodic’s amp off with its power switch (or in Settings → Your guitar) and your guitar plays exactly as it comes in, for your own amp, modeler or pedals in front of the interface. If your amp or interface already lets you hear your guitar, choose “I hear it already” in the setup’s Hear yourself step and Melodic won’t play it at all.

Good to know

What’s an amp sim?

An amp sim, short for amp simulator, is software that does what a guitar amp does: the preamp’s gain and tone controls, the power amp, and the speaker cabinet that shapes the sound, usually with effects pedals in front of it and behind it. You’ll also hear it called amp modeling or a virtual amp. A modeler usually means a hardware box that does the same job on a pedalboard.

Most amp sims are plugins for recording software. Melodic’s runs in your browser, so you can plug in and play through it with nothing to install, and it comes with a game that teaches you the songs to play through it.

Questions

About the amp

Is Melodic’s amp sim free?

Yes. The amp is part of Melodic, which plays free in your browser, and saving your own tones is free too.

Do I need to download anything?

No. Melodic runs in your browser on a computer, tablet or phone. On a computer you can also install it as an app if you like.

Can I just play my guitar through it, without a song?

Yes. Open Amp from the main menu and your guitar plays through it for as long as you like.

Does the amp sim add latency?

About half a millisecond: nothing in it looks ahead. The delay you hear comes mostly from your audio interface, your browser and your headphones. An audio interface and wired headphones give the lowest delay, and the setup shows the delay your computer reports.

Can I use my own amp, modeler or pedals instead?

Yes. Switch Melodic’s amp off with its power switch, or in Settings → Your guitar, and your guitar plays as it comes in. If your amp or interface already lets you hear it, choose “I hear it already” in the setup.

Does it work with a bass?

Yes. There are four bass amps (Bass, Pick Bass, Fretless and Slap), a 4×10 bass cabinet, the same five pedals and six bass tones.

Can I try the tones without a guitar?

Yes. Hear it plays a riff on Melodic’s modelled guitar through the amp, and every knob you turn is heard as you turn it.

Will my tones be on my other devices?

Yes, if you sign in: your saved tones go with your account. Without an account they stay on the device you made them on.

Does it work with a microphone?

Melodic hears a microphone fine, but only plays it back once you tell it you’re on headphones, since your speakers would feed back into it. For the amp, a cable or an audio interface sounds best.
