Blackstar IDX-50 Kitarski kombo – modelling

Blackstar ID:X 50 — 50W Digital Modeling Combo Amp

The ID:X 50 is a 50-watt digital modeling combo amp delivering six amp voices, 35 onboard effects, and patented ISF tone shaping from a single 1x12 cabinet. Power reduction scales output to 1W for silent practice, while CabRig DSP feeds a USB-C audio interface for direct recording. One compact enclosure replaces an entire pedalboard.

What sets this model apart

Two proprietary technologies define this amp. Blackstar's patented ISF sweeps the EQ continuously between British-voiced crunch and American-style punch, while CabRig is an IR-based DSP speaker simulator modeling cabinet, microphone, and room interactions in real time with zero latency. Switchable EL84, EL34, and 6L6 valve responses revoice the power stage from one button.

Power scaling and the Anthem 50 driver

Power scaling matters because a modeling amp should sound as good at whisper levels as it does at stage volume. This combo drops from 50W to 10W or 1W without tone collapse, and the 1x12 Anthem 50 speaker is voiced specifically to match the CabRig response curve.

• Power Output: 50 W — stage-ready headroom for rehearsals and small gigs
• Power Reduction: 50 W / 10 W / 1 W — three-position switch keeps tone intact at any volume
• The custom-voiced 12-inch Anthem 50 speaker is precision-engineered to perfectly complement CabRig profiles, ensuring authentic sonic depth for every preset.

Six voices, ISF, and switchable valve responses

Six preamp voicings span the full range from glassy cleans to saturated high-gain. A three-band EQ pairs with ISF for continuous tone-stack morphing, while the Response control swaps between EL84, EL34, and 6L6 power-stage emulations to revoice the entire amp character.

• Amp Voices: Clean Warm, Clean Bright, Crunch, Super Crunch, OD1, OD2
• EQ Section: Bass, Middle, Treble, ISF — three-band EQ plus patented ISF for British-to-American morphing
• Valve Responses: EL84, EL34, 6L6 — three switchable power-stage emulations

Onboard effects, CabRig, and studio-ready I/O

Over 35 onboard effects sit across four front-panel slots — Pre, Mod, Delay, Reverb — each with editable parameters visible on the OLED display. A full set of physical controls — Voice, Select Knob, Bank, Master, Mod, Dly, Rev, Tap, Response, Power, Level, Gain, Volume, Bass, Middle, Treble, ISF, and Manual — keeps every parameter one knob turn away. CabRig feeds the USB-C audio interface for direct DAW recording, with no Bluetooth in the signal path.

• Onboard Effects: 35+ effects across Pre, Mod, Delay, Reverb slots — pedalboard-grade processing without external gear
• Patch Memory: 12 onboard slots, 99 via Architect software — every saved tone one footswitch tap away
• Connect your gear via USB-C, 6.3 mm TS input, 3.5 mm line in, headphone output, or the integrated effects loop to handle all practice, recording, and performance needs.

Who should buy this instrument

This amp is the right choice for intermediate and gigging guitarists who want one amp to cover bedroom practice, home recording, and small-venue performances without hauling a pedalboard. Players stepping up from a Boss Katana or Line 6 Catalyst will find the valve-response switching and CabRig DSP a meaningful step up in feel and direct-recording quality. Bedroom players benefit most from the 1W power-reduction mode, which keeps the DSP in its sweet spot at whisper levels. Recording guitarists get a true USB-C audio interface with zero-latency cabinet simulation built in, eliminating the need for a separate load box or IR loader. The 9.6 kg weight and compact 470 x 409 x 221 mm footprint make it easy to carry to rehearsals and small gigs.
