Valeton GP-100 — Compact Floor Multi-Effects Processor with HD Amp Modeling

The Valeton GP-100 is a compact floor multi-effects processor that packs full rig functionality into a metal chassis measuring 198 × 134 × 28 mm. Inside sits an HD digital modeling engine running at 24-bit / 44.1 kHz with up to 9 simultaneous effect blocks. With 198 presets and a free PC/Mac editor, the unit covers practice and small gigs.

What Sets the GP-100 Apart in Its Class

The pre-effects looper is rare at this tier — when patches change, the looped phrase changes with them. 20 user IR slots let players load third-party impulse responses beyond the 40 factory cabs. The USB 2.0 Type-B port doubles as a stereo audio interface with an ASIO driver for Windows and OTG support for iOS and Android.

HD Modeling Engine — Specs That Shape the Tone

The modeling core determines how responsive the amp sims feel and how clean the signal stays through heavy chains.

• A/D/A Converter: 24-bit high-performance audio
• Signal-to-Noise Ratio: 110 dB — keeps high-gain patches free of hiss
• Maximum Simultaneous Effects: 9 blocks — headroom for full amp + cab + drive + mod + delay + reverb chains

Connections — Inputs, Outputs, and Audio Interface

The rear panel covers a typical home or small-stage rig.

• Guitar Input: 6.3 mm mono (TS), 1 MΩ impedance
• Outputs: 6.3 mm mono (TS) L/R — feeds a stereo amp or FRFR speaker
• Headphone Output: 3.5 mm stereo (TRS), 47 Ω impedance
• USB Port: USB 2.0 Type-B, 16-bit / 24-bit, 44.1 kHz — stereo audio interface with ASIO driver and OTG
