If you’re a guitarist who uses stompboxes, you’ve probably asked yourself the big question: “What order should my pedals go in?” It’s one of the most common topics we discuss with musicians, and for good reason. Should the wah go first? Does the compressor sound better before or after the overdrive? The placement of each pedal in your signal chain can dramatically change your final tone, opening up a world of sonic possibilities.
To demystify the process, we sat down with Sweetwater’s Mitch Gallagher and Don Carr to explore how different pedal orders affect your sound. They demonstrate that while there’s a “conventional wisdom” to pedal placement, the real magic happens when you start experimenting. Let’s dive in and build a functional, great-sounding pedalboard.
The Gear: Our Signal Path
Most experienced players follow a similar logic when building a pedalboard. As Sweetwater’s Don Carr puts it, the typical order is, “wah, compressor, gain pedals, volume pedal, modulation pedals, and then time-based stuff.” This sequence is designed to let each effect process the guitar signal in the most effective and musical way. To demonstrate, our signal chain starts with a Yamaha Revstar electric guitar and runs through a series of pedals including a wah, compressor, overdrive, and phaser. From there, it goes to a volume pedal with a dedicated tuner out, followed by delay and reverb, before finally hitting a classic Fender tube combo amp. This entire setup is housed on a Pedaltrain pedalboard.
Experiment 1: Gain Pedals vs. Filter Effects (Wah)
The most critical pedal to place in your signal flow is your overdrive or distortion. As Mitch Gallagher explains, “the way gain affects the sound of other effects is just ridiculous. I mean, that’s the most obvious thing.” The added harmonic content from a gain pedal dramatically changes how other effects, especially filters like a wah, respond.
- Wah Before Overdrive: This is the classic, most common placement. The wah pedal acts as a filter, shaping your clean guitar tone with a vocal-like sweep before it gets distorted. This results in a smooth, expressive lead tone that cuts through the mix without being overly harsh.
- Wah After Overdrive: When you place the wah after the overdrive, it filters the already harmonically rich, distorted signal. The effect is far more intense and aggressive, creating a synth-like, resonant sound that can be perfect for funk, electronic-inspired rock, or when you simply want a more extreme effect.
Experiment 2: Compressor vs. Overdrive
A compressor is designed to level out your dynamics—squashing loud peaks and boosting quiet parts to increase sustain. Its placement relative to your overdrive pedal completely changes its function.
- Compressor Before Overdrive: Placing a compressor like the Mini Ego first allows you to smooth out your clean guitar signal and add sustain before it hits the drive pedal. This results in a fatter, more controlled, and articulate distorted tone. It’s a popular choice for everything from country chicken pickin’ to tight metal rhythms.
- Compressor After Overdrive: Placing the compressor after the overdrive means it’s “squashing that distorted tone.” Since distortion already adds natural compression, this can result in a very squashed, less dynamic sound. While less common, it can be a useful textural effect for creating a super-even, sustained sound that almost sounds “re-compressed.”
Experiment 3: Modulation vs. Overdrive
Much like a wah, modulation effects like a phaser, flanger, or chorus are heavily influenced by gain. Using an MXR Phase 95, we can hear a distinct difference.
- Phaser Before Overdrive: The phasing effect is subtler and becomes more integrated into the core distorted tone. The “whoosh” is less pronounced, giving the sound a chewy, swirling texture without overpowering the guitar.
- Phaser After Overdrive: Here, the phaser is processing all the extra harmonics from the overdrive. This makes the effect much more dramatic. As Mitch notes, “All that extra content from the distortion… gives you a much more intense effect.” The swoosh is deep, rich, and very prominent.
Experiment 4: Time-Based Effects vs. Overdrive
Where you place your delay and reverb in relation to your gain stage is critical for achieving clarity. This is one area where the conventional wisdom is almost always followed for a very practical reason.
- Delay Before Overdrive: When you run a delay pedal like the El Capistan into an overdrive, the clean repeats from the delay are then fed into the gain pedal. Each repeat gets distorted, and because the overdrive boosts the signal, the repeats don’t decay naturally. This creates a sound that is often described as messy and chaotic, as the echoes pile on top of each other.
- Delay After Overdrive: This is the standard method. The overdrive distorts your initial note, and the delay cleanly repeats that distorted tone. This results in clear, distinct echoes that decay naturally without muddying the core sound. The same principle applies to reverb; placing it after distortion allows the reverb tail to decay smoothly.
Experiment 5: The All-Important Volume Pedal
A volume pedal is more than just an on/off switch for your sound; its function changes entirely based on its position in the chain.
- Before Overdrive: Placed at the front of the chain, the volume pedal acts exactly like your guitar’s volume knob. Sweeping it back reduces the signal hitting your gain pedal, cleaning up your tone. It becomes a dynamic tool for controlling the amount of drive with your foot. “It’s totally dynamic that way,” says Don.
- After Overdrive (but before delay/reverb): This is Don Carr’s preferred method. Here, the volume pedal acts as a master volume for your gain stage. You can set your ideal distorted tone and then adjust the overall level without affecting the amount of gain. A huge benefit is that when you swell down, the tails of your delay and reverb will continue to ring out naturally.
- At the End of the Chain: Placed last, the volume pedal is a true master volume for your entire pedalboard. It fades everything in and out, including the trails from your delay and reverb. This is great for creating smooth, ambient swells from silence or for a “hard stop” that mutes your entire signal chain.
Ultimately, the key takeaways are that your overdrive and volume pedals are the two most transformative effects when it comes to placement. Their position relative to your other pedals has a massive impact on the final sound. While the conventional wisdom provides a fantastic and logical starting point, don’t be afraid to experiment. You can’t hurt anything by swapping pedals around, and you might discover a unique sound that defines your style. As Don wisely puts it, “There’s no wrong answer here. It’s just whatever kind of result you want to get.”
