Should I Leave Effects On When Exporting Multitracks For Mixing?
When you’re preparing a song for mixing, one of the most common questions is:
Should I leave my effects on before exporting, or should I turn them off?
You might hear engineers describe this as sending tracks dry or wet.
In mixing, a dry track simply means the effects have been turned off before export. A wet track means the effects are printed into the audio, such as reverb, delay, distortion, amp sims, tuning, modulation, or other processing.
The short answer is:
Remove effects unless they’re essential to the sound, or the track would feel wrong without them. If the effect is essential, send the wet version. If you’re unsure, send both.
That gives the mixing engineer enough control to shape the song properly, while still preserving the sounds that genuinely matter to the production.

The Main Rule
The easiest way to decide is to ask one question:
Is this effect essential to the song?
If the effect was only added to make the rough mix feel better, it’s usually best to remove it before exporting.
If the track would sound wrong without the effect, send the wet version.
For example, a vocal reverb used just for monitoring probably shouldn’t be printed into the main vocal track. If it’s switched off for export, the rough mix can still be used as a guide to recreate a similar space in the mix if desired.
But if an effect is baked into the identity of the sound, such as a distorted vocal or a guitar amp sim creating a specific guitar tone, it should usually be included.
When in doubt, send both versions and label them clearly.
Vocals
For vocals, it’s usually best to turn off effects before exporting.
Printed reverb, delay, heavy compression, and EQ can limit what can be done in the mix. If a vocal already has a lot of reverb baked in, it can be hard to bring the vocal forward or place it in a different space later.
That doesn’t mean the effects you used in the rough mix will be ignored. If you had a plate reverb, delay, or other vocal effect that helped create the feel of the track, leave it on in the rough mix so I can use that as a guide and recreate the same kind of space properly in the mix.
With that said, if you’ve created a specific vocal effect that is essential to the song, such as a telephone effect or hard-tuned section, and it would sound wrong to remove it, send that printed version.
If you’re in any doubt, send both versions: one with the effects turned off, and one with the effects left on. Just label them clearly.
Guitars
Guitars are a slightly different case.
If you’ve used an amp sim to create the actual guitar tone, you should usually leave it on and export that sound.
The amp tone is often a huge part of the performance and arrangement. A clean DI guitar will naturally sound very plain, and if the mixer has to recreate the tone from scratch, it may end up sounding very different from what you had in mind. This is especially true in rock, metal, punk, indie, shoegaze, alternative, and other guitar-driven styles.
In most cases, send the guitar with the amp sim printed as the main track.
If you have the clean DI available, you can send that as a backup too. It gives the mixer an extra option if the tone needs support or re-amping later.
The exception is when the amp sim is genuinely just a placeholder, and you specifically want the mixing engineer to build the final guitar tone from scratch.
Bass Guitar
Bass guitar depends on the sound you’ve built.
If the bass is clean and simple, a DI may be enough. But if the tone relies on amp processing, distortion, saturation, chorus, synth layering, or another character effect, send the processed version. If you also have a clean DI, include it as a backup so the mixer can support the tone if needed.
Synths And Sound Design
For synths, virtual instruments, and sound design parts, it’s usually best to print the sound as you want it heard.
A synth patch might rely on delay, reverb, chorus, distortion, filtering, modulation, automation, or sidechain movement. If those effects are part of the patch or arrangement, they should usually be included.
Ask yourself:
Would this part still make sense without the effects?
If not, print it wet. You don’t need to include a dry version unless you’re unsure or want to give the mixer an extra option.
Drums
Drums depend on how they were created.
For live drums, it’s usually best to send the individual drum tracks as cleanly as possible, especially if the added processing is temporary. Printed reverb on close drum mics can be limiting, because compression and EQ can bring that reverb up in ways that are hard to control.
For live drums, a good approach is:
Send dry close mics where possible
Send overheads and room mics as recorded
Send any special drum effects separately
Include the rough mix so the intended drum sound is clear
For programmed drums, loops, and electronic drums, processing may be part of the sound. In that case, print the sound as intended, but separate the main elements where possible.
For example, send kick, snare, hats, percussion, loops, and drum effects separately rather than only sending one full drum stem.
When To Send Both Versions
If you’re unsure, send both.
You don’t need to send dry and wet versions of every track. Sending both is mainly useful when you’re not sure whether the effect should stay, or when you want to give the mixer a safety option.
This is especially useful when:
The effect might be important, but you’re not sure
You like the rough sound but want it improved
The part has a creative effect that may be hard to recreate
You have a DI and an amp-processed version
You’ve tuned a vocal but still have the original
Just make sure everything is clearly labelled.
For example:
Lead Vocal Dry.wav
Lead Vocal Wet.wav
Guitar L Amp.wav
Guitar L DI.wav
Bass Amp.wav
Bass DI.wav
Vocal Delay Throw.wav
Clear file names make the whole process much easier.
Don’t Forget The Rough Mix
Always include a rough mix.
The rough mix helps the mixing engineer understand your intended balance, effects, arrangement, vocal level, and overall direction.
It doesn’t need to sound polished. It just needs to show what you’ve been hearing while making the song.
A rough mix is especially useful when you’re sending dry tracks, because it shows how the effects and balances were working in your production.
For example, if you had a plate reverb on the vocal while producing the track, but switched it off for the dry vocal export, the rough mix gives me a clear guide for the kind of space you were hearing. I can then recreate that effect properly in the mix, with more control over how it sits.
Quick Checklist
Before sending your tracks for mixing, ask:
Is this effect part of the final sound?
Would the part lose its character if the effect was removed?
Is this processing creative, or was it only added temporarily for the recording phase or rough mix?
Would sending both dry and wet versions avoid confusion?
Are the files clearly labelled?
Have I included a rough mix so the intended effects and balances are clear?
If the answer is unclear, send both versions.
Quick Summary
For most mixing projects:
Send dry vocals unless an effect is essential to the sound.
Leave amp sims printed on guitars unless they are only placeholders.
Print synths and sound design with effects on if the effects are part of the sound.
Send both dry and wet versions when you’re unsure.
Always include a rough mix.
The aim is to give the mixing engineer enough control without losing the creative decisions that make the song feel like yours.
