The Blackstar HT20R MKII redefines the compact valve amp. Utilizing the iconic EL84 power amp design, you get unparalleled dynamics, response, and versatility. The HT20R MKII features Blackstar's best clean and overdrive tones, including sounds inspired by classic American & British amplifiers, from clear and punchy cleans to searing overdrive. Each channel is now equipped with a footswitchable voice mode, allowing for even more tonal flexibility. Joining Blackstar’s patented ISF tone control is a USB and balanced XLR outputs for pro recording, a power reduction switch, and a newly voiced studio quality reverb. The HT20R MKII is ideal for home, rehearsal, or studio use.

Blackstar's Best Clean and Overdrive Tones
The ground-breaking clean channel has two voices and offers the ultimate in clean tone quality and flexibility. One voice is based on a classic American circuit and the second channel is based on a classic British tone.  Boasting two richer, fuller and responsive voices on the Overdrive channels, the high gain voices are tight and focused, drawing on the original award-winning HT Series.

USB and Balanced XLR Outputs
The simplest way to get valve tone into your recordings. The flexibility of adding a USB connector allows for sending up to 4 channels of the guitar signal, dry, preamp out and stereo emulated out into a computer for recording purposes. Two further outputs on the rear, a stereo jack socket and balanced XLR, also allow the speaker emulated signals to be connected to external devices for practicing, recording or live use.

Power Reduction to 10% of the Amp
A switchable power reduction circuit has been included giving reliable, transparent attenuation down to 10 percent of the amp’s rated power. This means that the full tonal depth of the EL84 power stage can be enjoyed at any volume, retaining the distinctive sound of power valves working hard, making the HT MKII perfect for any live or recording situation.

Great amp for studio, stage or bedroom


Great amp - tremendous range of tones and flexibility. Able to play at bedroom volumes with the switch to 2 watt.



Pure Awesome


This amp is killer, whether in the studio or in a small gig. I'm not a fan of Blackstar but I can't deny how great this one in particular is. I was aiming more towards a Peavey Classic 30 or Fender Blues Jr, but I gave this one a chance on a whim. The cleans are nice and full, glassy if you want. Gain channel is incredibly versatile whether you're playing low or high gain. A simple overdrive or an EQ can really make this thing come to life that much more. Love the 2 watt setting too. I can't find any faults to this thing. No regrets



i would recommend


amazing tube amp. my first one i have had and im in love with the clean channel and esspecially the distortion, i love that it comes witha switch pedal. knobs work amazing and the 2 w option is exactly what im looking for !!!



Excellent tone at low volume


This amp is great for low-volume practice or recording, and it offers a wide variety of tones.



Blackstar = GOLD STAR!


This amplifier has amazing tone and the ISF feature just opens so many tonal doors. This purchase has made me a believer in Blackstar. I will definitely be checking out more from their lineup before shopping any other brands from here out.





Amazing sound. Easy to use. Unbeatable tone.
