The Valeton GP-5 is a compact multi-effects processor and amp simulator designed to offer tremendous sonic versatility in a pocket-sized format—ideal for practicing guitar or as part of a pedalboard. It features a high-quality digital processing engine (24-bit/44.1 kHz) and includes over 100 effects, amp, and cabinet models that can be combined into up to 100 presets (50 factory and 50 user presets), each incorporating up to 9 simultaneous modules in customizable chains.
It features intuitive controls on its physical panel for quick parameter adjustment, as well as a clear display for navigating presets. It can load up to 20 IR files from third-party cabinets and import NAM (Neural Amp Modeler) files using SnapTone technology, and it can store up to 80 NAM files in total. It also includes essential practice features such as a drum machine with 100 built-in patterns, a stem splitter, and a precise chromatic tuner.
To manage presets and edit parameters, you can connect the GP-5 to PC/Mac software and an Android app. All of this is complemented by a 1/4″ (TR/TRS) mono/stereo combo output for use with headphones or for direct connection to an amplifier or mixing console, or for integration into a pedalboard.
Connection to PC/Mac and Smartphone
The Valeton Suite software allows you to connect the GP-5 to a PC or Mac to manage NAM and IR file slots and presets. It also allows you to back up presets and update the firmware.
The Valeton Suite app for Android/iOS connects to the pedal via Bluetooth and allows you to edit presets (enable, disable, and edit the 9 modules in the effects chain), manage presets, load IR files into internal memory, and load/convert NAM files. It also lets you use the drum machine and stem splitter, configure the Valeton GP-5’s settings as an audio interface, and set the pedal switch’s operating mode.
NAM File Compatibility
SnapTone compression technology converts large NAM neural network files by extracting and distilling their key tonal characteristics (frequency response, dynamic saturation, and nonlinear behavior), transforming them into a lighter, optimized digital file. Since the Valeton GP-5’s processor has limited DSP resources and memory, the original NAM files—which require significant processing power on a PC—cannot be run natively. During this conversion process, the NAM file undergoes a slight reduction in the mathematical resolution of the amplifier model. This subtly affects the microdynamics and the feel of the pick response, though it preserves the essential tone and character of the original amplifier. Thanks to this technical optimization, the pedal can store up to 80 of these advanced captures without overloading its internal system or introducing perceptible latency during performance.
IR and NAM files are permanently loaded into the GP-5’s memory: once the files are transferred to the assigned slots, they are saved in the pedal’s internal memory. Once transferred, you no longer need to be connected to computer software or your phone. You can integrate these slots into your user presets via editing and access them directly using the pedal switch. Note: Make sure the native NAM file includes, at a minimum, an amp and cabinet simulation. In the effects chain, these slots appear when editing the N-S module; activating this module automatically deactivates the amp and cabinet modules.
Other Useful Features
Audio Interface: The Valeton GP-5 includes a built-in USB audio interface with 2 inputs and 2 outputs (2 In / 2 Out) that allows you to record directly to a PC, Mac, iOS, or Android device via the USB-C port. It operates at an audio resolution of 24-bit / 44.1 kHz, with adequate dynamic range and low latency for real-time monitoring. On Mac, iOS, and Android, it’s plug-and-play; on Windows, it’s recommended to install Valeton’s official ASIO drivers to minimize latency when recording within a DAW. The USB-C port transfers audio while simultaneously powering the pedal (5 V minimum), so there’s no need to connect the 9 V power supply when using it with a PC or laptop. Its direct monitoring feature lets you hear the processed signal in real time through the 1/4″ headphone output without the latency of the computer’s processor.
Stem Splitter: This is an AI-powered feature that allows you to separate an already mixed song (a complete audio file such as an MP3 or WAV) into its individual tracks or instruments (stems). The components that are separated are: vocals, drums, bass, and harmonic instruments (guitar or others). Although this feature is not built into the hardware or firmware of the Valeton GP-5 pedal itself, it is very useful for practicing or creating backing tracks.
Valeton GP-5 User Community
Unlike other guitar processor manufacturers (such as Line 6 or IK Multimedia), Hotone does not maintain a cloud-based GP-5 user community for sharing presets. It’s a shame that Hotone doesn’t recognize the enormous added value that maintaining a user community could bring to the GP-5. There are several Facebook groups for sharing Valeton GP-5 presets. The native NAM files (more than 750,000) are available for free at www.tone3000.com
