Advanced Multi-Effects Processing

The GP-100 provides more than 140 high-quality effects covering essential categories such as dynamics, overdrive, distortion, EQ, modulation, delay, and reverb. Its editable effects chain allows you to arrange the available processing modules to create personalized signal paths for different instruments, songs, and playing styles.

With support for up to 9 effects simultaneously, the GP-100 can function as a complete digital pedalboard. You can build anything from simple amp-and-reverb setups to more complex chains combining compression, distortion, modulation, delay, and cabinet simulation.

Guitar, Bass and Acoustic Amp Modeling

The GP-100 includes 45 amp simulations covering guitar, bass, and acoustic applications. This broad selection allows the processor to adapt to different instruments and musical styles, providing a convenient way to explore a wide range of amplifier-inspired tones without carrying multiple amplifiers.

The amp modeling can be combined with cabinet simulation and effects to create complete ready-to-play tones for rehearsal, recording, direct performance, and headphone practice.

Cabinet IR Support

Alongside its 40 factory cabinet IRs, the GP-100 supports third-party impulse responses and provides 20 user IR storage slots. This allows players to customize their cabinet sounds and experiment with additional impulse responses to create a more personalized digital rig.

User IR support is particularly useful for direct recording and modern amplifier-modeling workflows, where cabinet response plays an important role in shaping the final guitar tone.

Flexible Preset System

The GP-100 provides 198 preset locations, including 99 factory presets and 99 user presets. The factory presets are designed to cover a broad selection of musical styles, while the user preset locations provide ample space for saving customized sounds.

This preset architecture makes it easy to organize sounds for different guitars, songs, rehearsals, recording sessions, or live performances.

Built-In Expression Pedal

The integrated expression pedal provides hands-free real-time control over compatible parameters. Depending on the selected effect or preset, it can be used for functions such as volume, wah-style control, modulation, or other assignable effect parameters, adding greater expressiveness to live playing.

90-Second Pre-Effects Looper

The GP-100 features a pre-effects looper with up to 90 seconds of recording time. Because the looper is positioned before the effects processing, changing presets or effects can also change the way the recorded loop is processed. This makes it particularly useful for experimenting with different tones and developing musical ideas.

The looper is a valuable creative tool for practicing lead lines, building layered parts, testing effects, songwriting, and creating solo performance arrangements.

Built-In Drum Machine

The integrated drum machine provides 100 high-quality rhythm patterns, including metronome-style patterns, giving guitarists a convenient rhythmic accompaniment for practice and songwriting. Combined with the looper and auxiliary input, the GP-100 can provide a complete practice environment without requiring additional equipment.

USB Audio Recording

The GP-100 can function as a USB audio interface with stereo audio streaming. Connect it to a compatible computer or mobile device to record guitar directly into your music software, develop song ideas, or mix and share recordings.

For Windows users, compatible ASIO driver support provides low-latency recording and monitoring, while the USB connection makes the GP-100 a practical choice for home studios and portable recording setups.

Flexible Practice Connectivity

The stereo auxiliary input allows you to connect an external audio source such as a smartphone, tablet, or music player. This makes it easy to play along with backing tracks while using the headphone output for quiet practice.

The dedicated headphone output is also useful for late-night practice, home recording, and monitoring your guitar without connecting to an amplifier.

Two Footswitch Modes

The GP-100 provides two selectable footswitch modes designed for different playing situations. Patch Mode allows the footswitches to be used for changing presets, while Stomp Mode allows individual effects within a preset to be switched on or off.

This flexible approach makes the GP-100 suitable for both straightforward preset-based setups and more interactive live performance configurations.

Durable and Portable Design

The GP-100 features a full-metal chassis and durable footswitches designed to withstand regular use. Despite its robust construction, the unit measures 198mm x 134mm x 28mm and weighs approximately 800g, making it convenient to carry between home, rehearsal rooms, studios, and performance venues.

Ideal for Practice, Recording and Live Performance

The Valeton GP-100 is designed to cover a wide range of applications, from beginner practice and tone exploration to advanced recording and live performance. Its combination of amp modeling, cabinet IRs, extensive effects, presets, expression control, looper, drum machine, USB audio, and flexible outputs makes it a complete and portable guitar processing solution.

Whether you want to build a compact digital pedalboard, practice silently with headphones, record directly into a computer, experiment with different amplifier tones, or create complete live presets, the GP-100 provides the tools needed in one convenient unit.
