High-performance power and tone
The Blackstar IDX:50 is a powerful 50-watt digital combo amp with selectable output settings of 1W, 10W, and 50W. This flexibility lets you move effortlessly from home practice to rehearsal or live gigs without sacrificing tone or feel. Its compact design makes it ideal for any environment, while still packing serious volume and punch when needed.
Iconic amp voicings with valve feel
With six distinct amp voices built into the IDX:50, you can easily explore everything from clean and chimey tones to rich crunch and searing high gain. Selectable EL84, EL34, and 6L6 response options give you the authentic dynamics and character of classic valve amps, with digital precision and consistency.
Built-in effects and deep editing
Over 35 built-in effects, including modulation, delay, and reverb, are available straight from the amp—no external software or app required. The built-in screen allows you to select, tweak, and fine-tune multiple effect parameters in real time, offering the kind of deep editing you'd normally find in complex multi-FX setups.
Studio-ready connectivity
Equipped with CabRig speaker simulation, balanced XLR output, USB-C, and a ¼” line out, the IDX:50 makes it easy to connect to recording interfaces, mixers, or live rigs. It also supports external footswitches like the FS-12 and FS-18, giving you hands-free control over patches and functions for seamless performance on stage or in the studio.
