Built Different.
ReaperBoost-1K faithfully captures the unmistakable character of a legendary onboard preamp—bringing a defining metal guitar tone into the modern plugin world for the first time.
Enhanced with subtle workflow and performance improvements, it delivers the aggression, clarity, and response that defined an era of Finnish melodic death metal—instantly recognisable to fans of early 2000's European metal guitar.

LIMITED INTRO OFFER - $30 USD
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.

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.
