What Reamping Means and Why You'd Do It

Reamping is recording a new amplifier sound by playing back a guitar recording through an amp and microphone, then capturing that new sound. You record the guitar part once, then later send that recording through a different amp, different settings, or a different room to get a fresh tone without re-recording the original performance.

This is useful when you want to try a different amp sound after the fact, when you recorded guitar direct-to-interface and want to add amp character, or when you're mixing and realize the original amp tone doesn't fit the song. Instead of asking the guitarist to come back and play the part again, you reamp the existing take.

Key Takeaways

  • Reamping requires a clean, unprocessed guitar recording (no amp simulation, compression, or effects) sent back through a real amplifier and microphone.
  • You need a reamp box or DI box set to line-level output to convert the audio signal from your interface back to instrument level so the amp will respond correctly.
  • The amp, microphone placement, room, and microphone choice all affect the final tone, so you can experiment with settings you couldn't change during the original recording.
  • The reamped recording becomes a new track in your mix that you blend with or replaces the original guitar track.

Preparing Your Original Guitar Recording

The guitar track you reamp must be clean and unprocessed. That means no amp simulation, no compression, no reverb, no EQ, and no effects. If you recorded guitar direct-to-interface during the original session, you already have what you need. If the original take went through an amp and microphone, you cannot reamp it—the amp coloration is already baked in.

Export the guitar track as a stereo or mono WAV file at the same sample rate and bit depth your interface uses (usually 44.1 kHz or 48 kHz, 24-bit). Do not compress the file or explore any processing during export. Save it somewhere you can find it easily, because you'll load it into your playback device next.

Setting Up the Reamp Chain

You need four pieces of equipment in order: your playback device (computer or audio interface), a reamp box, the guitar amplifier, and a microphone. The reamp box sits between your interface output and the amp's input. It converts the line-level signal from your interface (which is too hot and the wrong impedance) into instrument-level signal that the amp expects.

Connect your interface's output to the reamp box's input using a balanced XLR or quarter-inch cable. Connect the reamp box's output to the amp's input using a standard guitar cable. Set the reamp box's level control so the amp responds the same way it would to a guitarist playing at normal volume—you should see the amp's input meter moving into the normal range, not pinned or barely moving.

If you don't have a reamp box, a passive DI box with a ground-lift switch and a line/instrument toggle can work in a pinch, though a dedicated reamp box gives you better level control and impedance matching.

Choosing Amp Settings and Microphone Placement

This is where reamping pays off. You can now try amp settings, cabinet positions, microphone types, and room placements that you couldn't experiment with during the original take. Play back a section of the guitar recording and listen to how the amp responds. Adjust the amp's gain, tone stack, and volume until you hear the character you want.

Position your microphone in front of the amp's speaker. Start with the mic pointing at the speaker cone about 6 to 12 inches away—closer gives more attack and high-end detail, farther away gives a rounder tone. Angle the mic slightly off-axis (not pointing straight at the center) to reduce harshness. If you're using a condenser microphone, keep it away from the amp's cooling fan noise.

The room matters too. A small, treated room will sound tight and controlled. A larger, untreated room will add natural reverb and space. If you reamped in a different room than the original recording, the reamped tone will sound like it came from a different space, which can be obvious in a mix.

Recording the Reamped Signal

Set up a new track in your DAW (Digital Audio Workstation) and arm it for recording. Set the input to the microphone channel. Play back the original guitar recording through the reamp chain while the new track records. Do a test pass first to check levels—the microphone should hit around -6 dB to -3 dB on the loudest peaks, leaving headroom so the recording doesn't clip.

Record the entire guitar part, or at least a full section so you can hear how it sits in context. Once the recording is done, stop playback and save the file. You now have a new guitar track with the amp tone you wanted.

Blending or Replacing the Original Track

Mute the original guitar track and listen to the reamped version alone. Does it have the tone you wanted? If yes, you can delete the original track or keep it muted as a backup. If the reamped tone is close but not quite right, try adjusting the amp settings and recording another pass.

Some engineers blend the original and reamped tracks together—pan them slightly apart or layer them to get thickness and character from both. Others replace the original entirely. There's no rule; it depends on what sounds best for the song. If you reamped multiple guitar parts, you can reamp them all through the same amp settings to keep them consistent, or reamp each one differently if the song calls for variety.

Common Mistakes to Avoid

The most common mistake is reamping a guitar track that already has amp simulation or heavy processing on it. The amp will respond unpredictably and the tone will sound muddy or strange. Always start with a clean, dry recording.

Another mistake is setting the reamp box level too hot or too quiet. If the amp is getting too much signal, it will distort even if you didn't intend that. If it's getting too little, the tone will sound thin and weak. Spend a minute dialing in the level before you record.

Finally, don't forget that the reamped recording will sound like it came from a different amp and room than the original. If you're reamping only some of the guitar tracks in a song, the ones you didn't reamp will sound noticeably different. Either reamp all the guitar parts or none of them, unless you're going for a deliberate contrast.

Frequently Asked Questions

Can I reamp a guitar track that has reverb or delay on it?

No. Reverb and delay are time-based effects that will confuse the amp and create a washy, unclear tone. You need a completely dry recording. If your only take has effects, you cannot reamp it.

What if I don't have a reamp box?

A passive DI box with a ground-lift switch and line/instrument toggle can work as a substitute, though it won't give you as much level control. In a pinch, some engineers use a volume pedal or attenuator between the interface and amp, but this is less reliable.

Do I need the same amp I used on the original recording?

No. That's the whole point of reamping—you can use a different amp, different settings, or even a different amp model. You can reamp through a vintage tube amp, a solid-state amp, a combo, a head and cabinet, or any amp you have access to.

Will the reamped track sound exactly like a fresh recording?

Not exactly. The original performance is the same, so the timing and dynamics are identical. But the tone, room character, and microphone choice will be different. In a mix, the reamped track will sit in a different sonic space than the original.

Can I reamp bass the same way?

Yes. The process is identical—clean bass recording, reamp box, bass amp, microphone. Bass reamping is common in studios because bass tone is so critical to a mix and hard to get right on the first take.
