Next-Generation HD Modeling

The GP-150 is powered by Valeton's second-generation HD digital modeling technology, providing a significant processing upgrade for players who want detailed amp, cabinet, and effects tones. Its 48kHz sampling rate and redesigned cabinet simulation are designed to deliver greater clarity, realism, and responsiveness across the entire signal chain.

With more than 200 premium effects built into the processor, the GP-150 provides an extensive tonal palette for creating clean, crunch, overdrive, distortion, modulation, delay, reverb, and other professional guitar sounds.

SnapTone and Neural Amp Modeler Support

The GP-150 supports Valeton's latest SnapTone technology, allowing compatible Neural Amp Modeler files to be converted and loaded into the processor. This opens up a broader range of amplifier and tone profiles beyond the built-in modeling library.

The SnapTone module includes 50 curated files and provides storage for up to 100 SnapTone files, giving players plenty of room to build a personalized collection of tones for different guitars, genres, songs, and performance setups.

Third-Party Cabinet IR Loading

The GP-150 supports third-party cabinet impulse responses with both 1024 and 2048 sampling points. Up to 20 third-party IR files can be stored, allowing you to customize the cabinet section of your signal chain and create highly personalized direct tones.

IR support is especially useful for recording and live applications where the GP-150 is connected directly to a mixer, audio interface, powered speaker, or other full-range audio system.

Flexible 12-Module Effects Chain

One of the GP-150's major upgrades is its ability to run up to 12 effects modules simultaneously. Each module can be arranged in the desired order, allowing you to create signal chains that closely match your preferred pedalboard or studio workflow.

The redesigned operating system provides intuitive drag-and-drop routing and deeper parameter control. This makes it easier to experiment with signal paths, reorganize effects, and create highly customized patches without being restricted to a fixed effects order.

200 Patch Slots

The GP-150 provides 200 patch locations, including 100 factory patches. The expanded memory gives players more room to save customized sounds for different instruments, songs, musical styles, rehearsals, recording sessions, and live performances.

Factory patches are organized for practical use, giving you quick access to a wide variety of ready-to-play tones without requiring you to build every sound from scratch.

2.4-Inch HD Color Display

The 2.4-inch HD color LCD display provides a clear and intuitive interface for navigating presets, adjusting effects, managing signal chains, and viewing system information. The larger color display makes operation easier during rehearsals, recording sessions, and live performances.

Additional physical controls, dedicated buttons, and a master volume knob provide direct access to important functions without requiring constant menu navigation.

Expression Pedal and Dual Footswitch Control

The integrated expression pedal provides real-time hands-free control over compatible parameters, allowing you to manage functions such as volume, wah, modulation, or other assigned effects while playing.

The dual footswitch design provides practical live control, allowing up to six effect modules to be toggled and providing access to tap tempo and synchronization functions. Color-changing footswitch rings and multiple status indicators provide clear visual feedback while performing.

Built-In 180-Second Looper

The GP-150 features a looper with up to 180 seconds of recording time, providing plenty of space for practicing, songwriting, improvisation, and creating layered musical performances.

The extended loop time makes the GP-150 particularly useful for developing complete ideas, practicing solos over rhythm parts, experimenting with effects, and creating solo performance arrangements.

HD Drum Machine

The integrated drum machine provides more than 100 built-in HD rhythm patterns for practice, songwriting, and improvisation. Drum patterns can provide a consistent rhythmic foundation without requiring an external drum machine or computer.

The companion mobile application also provides access to 100 drum machine rhythms, giving players additional options for practicing and developing musical ideas.

Advanced Tuner

The GP-150 features an accurate and responsive tuner with a cent display for precise tuning adjustments. Multiple tuning templates support a wide range of alternate tunings, making the tuner useful for players who regularly switch between standard and alternate guitar tunings.

6-In/4-Out USB Audio Interface

The GP-150 doubles as a 6-in/4-out audio interface, providing extensive connectivity for computer-based recording and music production. It can connect to Windows, Mac, iOS, and Android devices, making it suitable for home studios, mobile recording, livestreaming, and content creation.

The USB connection also supports MIDI control, allowing the GP-150 to communicate with compatible software and hardware while serving as part of a broader music production setup.

Bluetooth Wireless Connectivity

Built-in Bluetooth 5.0 dual-mode connectivity supports both BLE communication and wireless audio. Bluetooth audio allows you to play music or backing tracks wirelessly through the GP-150, while the wireless connection can be used with compatible iOS and Android companion applications.

The mobile application provides functions such as tone editing, wireless playback, patch management, updates, and access to additional drum rhythms, giving you convenient control from a compatible smartphone or tablet.

MIDI and External Control

The GP-150 supports MIDI control through USB, Bluetooth, and 6.35mm TRS connections. Expansion ports also support external expression pedals and footswitches, allowing you to expand the control options for more complex performance setups.

This makes the GP-150 suitable for players who want to integrate a multi-effects processor into a larger MIDI-controlled pedalboard, studio rig, or performance system.

Headset and Streaming Support

The dedicated 3.5mm TRRS headset output supports compatible headsets with microphone functionality, making the GP-150 useful for livestreaming, online guitar lessons, remote teaching, and communication-based music applications.

Combined with the 6-in/4-out audio interface and Bluetooth capabilities, the GP-150 can serve as a flexible audio hub for modern content creation and online performance workflows.

Rechargeable Battery

The built-in 3000mAh rechargeable battery provides more than 6 hours of operating time under specified display brightness conditions. This makes the GP-150 convenient for mobile practice, rehearsals, outdoor sessions, travel, and situations where access to mains power is limited.

The battery can be charged through either the DC 9V input or USB-C connection. USB Power Delivery fast charging is supported, and the USB connection can also provide reverse power to compatible devices.

Flexible Output Options

The GP-150 provides stereo balanced and unbalanced output capability, allowing it to connect to a wide variety of amplifiers, powered speakers, mixers, audio interfaces, and full-range speaker systems.

It can be used directly with full-range speaker systems, connected to a guitar amplifier input, integrated through an amplifier's effects loop, or positioned within a larger signal chain using external control devices.

Ideal for Live Performance, Recording and Practice

The Valeton GP-150 is designed to function as a complete modern guitar processing system. Its combination of advanced modeling, SnapTone technology, third-party IR support, extensive effects, flexible routing, large preset capacity, looper, drum machine, MIDI, USB audio, Bluetooth, and rechargeable battery makes it suitable for a wide range of musical applications.

Whether you are building a compact live rig, recording directly into a computer, practicing with headphones, livestreaming, integrating external pedals, or creating complex studio signal chains, the GP-150 provides the processing power and connectivity needed to adapt to your workflow.
