Blackstar Debut 50R Union Flag — British tube power in a fully analogue format

We’ve received the new Blackstar Debut 50R, and it instantly proved itself as one of the most impressive analogue combos in its class. True to the Debut philosophy — “All tone. No fuss.” — this amplifier delivers a full professional voice without unnecessary digital complexity. Designed by the same UK R&D team behind Blackstar’s award-winning valve amps, the Debut 50R offers rich analogue response and inspiring dynamics that make you want to play more.

🎸 Professional Sound From the First Chord

Thanks to Blackstar’s exclusive MOSFET preamp design, the Debut 50R captures the feel and behaviour of a real valve amplifier. The clean channel delivers open, articulate clarity with plenty of headroom, while the overdrive channel channels the character of the St. James 6L6 series — from bluesy bite to full modern crunch.

⚙️ Next-Level MOSFET Engineering

Borrowing topology from Blackstar’s flagship valve series, the MOSFET preamp recreates the warmth, harmonic complexity, and touch sensitivity of tubes — all inside a lightweight fully analogue platform.

🔥 A True Gig-Ready Workhorse

With 50 watts of output, the Debut 50R comfortably fills rehearsal rooms and small to medium venues. It’s also an exceptional pedal platform, making it a reliable main amp for gigging guitarists and a perfect upgrade for players seeking real analogue character.

🧰 Features That Matter

The Debut 50R keeps only what’s essential — everything designed with players in mind:

🎚️ Two footswitchable channels — Clean & Overdrive
🎛️ ISF tone shaping — American to British voicing
🔄 Series FX Loop — perfect for delays & modulations
🔉 Power reduction to 5W — natural tone at home volumes
🌫️ Plate/Hall reverb — lush ambient space

The clean channel is voiced after the HT-20R MKII for maximum clarity and headroom, while the OD channel brings the punch and saturation of the St. James 6L6 series.

🎧 Silent Practice, Studio-Ready Output

The onboard Speaker-Emulated Headphone/Line Out provides realistic cabinet response, making the Debut 50R ideal for silent practice and direct home recording.
