The Gigagain GP03 Gainster is a high-gain preamp and distortion pedal designed for heavy music. It can be used as a traditional distortion pedal in front of an amplifier or as a dedicated preamp connected directly to the FX Loop Return. When used as a preamp, it functions as the preamplifier and provides a direct, controlled and modern high-gain sound.

• High-gain preamp and distortion in one pedal
• Can be connected directly to the FX Loop Return as a preamp
• Two channels for different heavy genres
• Analog circuitry and a robust aluminium housing

Two channels for different gain approaches

Gainster features two separate high-gain channels, making it easy to switch between different sounds.

• CH.1: Designed for melodic playing and leads, with a full and detailed tone, good sustain and definition.
• CH.2: Designed for heavier riffs and more aggressive playing, delivering a tighter low end and a more immediate attack. Suitable for modern rock and metal.

Three-band EQ

The built-in three-band EQ with Bass, Mid and Treble controls provides precise tone shaping. It can be used to tailor the sound to your guitar, amplifier and playing style, from a scooped metal tone to a more mid-focused lead tone.

Flexible integration

Gainster can be used in two ways:

• In front of the amplifier as a traditional high-gain distortion pedal
• Directly into the FX Loop Return as a dedicated preamp

This makes the pedal suitable for both simple setups and more complex rigs.

Thoughtful design

The dedicated power switch allows the power to be fully cut off, helping to prevent unnecessary battery drain and protecting the components. Buffered bypass helps maintain a stable signal path. The analog circuitry and aluminium housing provide a responsive and dynamic playing experience, even at high gain levels. Its compact format makes it easy to integrate into a pedalboard.
