How to Make a Reese Bass in Serum: The Complete Guide for Every Genre

What Is a Reese Bass

The Reese bass is one of the most iconic sounds in electronic music. Named after Kevin Saunderson, who released tracks under the name Reese, this bass sound has been the foundation of drum and bass, dubstep, garage, and countless other bass-heavy genres for over three decades. At its core, the Reese is deceptively simple: two detuned saw waves creating a thick, phasing texture. But the variations and processing possibilities are virtually endless.

The beauty of the Reese is its versatility. A gentle, warm Reese works in liquid DnB. A heavily distorted, aggressive Reese powers neurofunk. A filtered, rolling Reese drives jump up. Understanding how to build a Reese from scratch in Serum gives you a foundation that applies to almost every bass music genre.

Building the Basic Reese in Serum

The Two-Oscillator Foundation

Load Serum and set Oscillator A to a basic saw wave. Set Oscillator B to the same saw wave. Now detune Oscillator B by about 5 to 15 cents (0.05 to 0.15 semitones). This slight pitch difference between the two oscillators creates a beating, phasing effect as the waveforms move in and out of phase with each other. That beating is the core character of the Reese bass.

Start with a subtle detune of about 7 to 10 cents and play a low note around C1 or D1. You should hear a thick, churning bass with slow movement. Increase the detune for faster beating and a more aggressive texture. Decrease it for a smoother, subtler phase effect.

Adding Unison for Width

For a wider, thicker Reese, add unison voices to each oscillator. Set both Oscillator A and B to 2 or 3 unison voices with light detune (around 0.10 to 0.20). This multiplies the number of slightly detuned waves interacting, creating a richer, more complex phasing texture. Be careful not to overdo the unison detune, as it can make the bass sound thin and unfocused if pushed too far.

Processing the Reese for Different Genres

DnB Reese

For drum and bass, the Reese should be warm and deep with controlled mid-range presence. Apply a low-pass filter at around 800 Hz to 1.5 kHz to tame the brightness. Use an LFO on the filter cutoff at a very slow rate (1/2 bar or 1 bar) for gentle tonal sweeping. Add a touch of chorus in the FX chain for extra width.

Layer a clean sine sub underneath, high-pass the Reese at around 80 to 100 Hz, and let the sine handle the sub frequencies. This gives you a clean, powerful low end with the Reese character sitting above it.

Dubstep Reese

For dubstep, push the Reese harder with more detune (15 to 25 cents) and add distortion. Use the Hyper/Dimension effect in Serum for extra width, then apply the distortion module set to “Diode” or “Tube” mode. The result is a thick, gritty bass with lots of mid-range harmonic content.

Add an LFO to the filter cutoff at a faster rate (1/4 or 1/8 notes) for a wobbling effect. Automate the LFO rate for variation across your bass pattern. This transforms the static Reese into a dynamic, modulating bass sound.

Garage and Bassline Reese

For UK garage and bassline, keep the Reese relatively clean but with a distinct wobble. Use less detune (5 to 10 cents) and apply a low-pass filter with a moderate LFO rate. The garage Reese should be smooth and rolling, not aggressive or harsh. Add a touch of saturation for warmth and keep the overall tone round and full.

Advanced Reese Techniques

The Talking Reese

Create a vowel-like quality by using two band-pass filters in parallel at different frequencies. Set one filter around 400 Hz and the other around 2 kHz. Automate both filter frequencies simultaneously to create formant-like sweeps that make the Reese sound like it is talking or singing. This technique is popular in neurofunk and experimental bass music.

The Modulated Reese

Assign multiple modulation sources to different parameters. Put an LFO on the detune amount, another on the filter cutoff, and a third on the wavetable position (if using a wavetable instead of a basic saw). These overlapping modulations create a constantly evolving texture that never repeats exactly. Map the key modulation sources to macros for easy real-time control.

Mixing the Reese Bass

The Reese bass can easily dominate a mix if not handled carefully. Always split it into sub and mid-range layers for independent processing. Compress the sub layer for consistency and apply controlled distortion to the mid-range layer for character. Sidechain both layers to your kick for clean kick-bass separation.

Mono your sub content below 100 to 150 Hz. The phasing character of the Reese can cause phase cancellation issues in the low end on mono systems. Keep the width in the mid-range and above, where it adds interest without causing problems.
