Reaperboost - 1k

A legendary tone—reimagined for modern production.

For years, this tone was locked inside the guitar itself—only accessible through hardware modification, with little room to adapt or refine.
ReaperBoost - 1K brings that sound into your DAW for the first time—faithfully recreated, with the freedom to shape, tweak and refine it in ways that were never possible before.

Features & Controls

- Pickup Emulation -

A Defining Part of the Tone
ReaperBoost1K includes two dedicated pickup emulation stages, designed to recreate the tonal character of a classic J50BC pickup associated with this sound as well as the more contemporary ALX pickup.
More than a static EQ curve, this stage dynamically responds to your input signal—shaping the attack, resonance, and harmonic content before it even reaches the boost circuit.

Boost - Controls the amount of gain introduced by the circuit.
Just like the original hardware, this defines the core drive and intensity of the tone.

Peak - A modern addition—something the original always needed. Peak controls the intensity and character of the EQ effect, allowing you to move from narrow and aggressive to broader, more musical shaping.

Output - The missing piece. Output gives you full control over your gain staging, ensuring the signal hits your amp or plugin chain exactly how you want it—without compromise.

Pickup Resonant Frequency - Redesigned for clarity and control. This parameter lets you precisely position the resonant peak that defines the tone—replacing the limitations of mini dip switches with a smooth, intuitive control. The marked position captures a familiar, instantly recognisable character—while allowing you to explore beyond it.

REAPERSUITE

Six eras of Finnish melodic metal—brought into one platform.

ReaperSuite is built around a ground-up approach to capturing tone—recreating the character, response, and feel of six distinct stages in the evolution of a defining guitar sound.ReaperSuite isn’t based on approximations or generic models.
Every channel is built from the ground up to preserve the identity of the original tone—while removing the limitations that once came with it.
Originally, these sounds were fixed—tied to specific rigs, settings, and moments in time.
Now, they’re fully accessible.
Switch between eras instantly.
Dial them to your guitar, your tuning, and your mix.
Push beyond what was possible before—without losing what made them iconic.

Features & Controls

Noise Gate
A fast, transparent gate designed for tight, controlled performance—essential for high-gain clarity without choking sustain.
Oversampling
High-quality internal processing ensures clarity, depth, and reduced aliasing—maintaining detail even under extreme settings.
Gain
Fine control over input drive, allowing you to match or push each tone beyond its original limits.
Resonance
Shapes the low-end response and feel, adapting the tone to different guitars, tunings, and playback systems.
Presence
Controls the upper frequency response and attack, helping the tone cut through dense mixes.

Bassreaper

Mix-Ready Finnish Melodic Death Metal Bass tones in one click.

Designed to work seamlessly within the HALF//SUN DSP ecosystem, BassReaper delivers cohesive, mix-ready bass tones that lock perfectly with any model in the ReaperSuite and beyond. Every stage is tuned with the full mix in mind, so your bass doesn’t just sound good — it fits.

Features & Controls

BassReaper is built around a three-path processing system, designed to deliver a complete, mix-ready bass tone from a single plugin.
At its core, the signal is split into three complementary chains:7K DRIVE MODULE
A modern 7K-style drive stage adds string definition, articulation, and aggressive midrange clarity, ensuring your bass cuts through dense mixes without losing control. An independent, modern noise gate is added for perfect control.

PARALELL AMP MODULE
The secret sauce! A dedicated parallel amp chain with three selectable modes shapes how your bass interacts with guitars — adding body, depth, and harmonic character that helps it sit naturally in the mix. Another independent noise gate is added to ensure perfect gating across different distortions.

SUB MODULE
A clean, low-frequency layer provides a solid and consistent foundation, delivering controlled weight and punch without mud or instability.

These three paths are then combined and passed through a custom cabinet impulse, carefully voiced to shape the final result into a polished, mix-ready bass tone.
