The Blackstar HT20RH MKII redefines the compact valve amp. Utilizing the iconic EL84 power amp design, you get unparalleled dynamics, response, and versatility. The HT-20RH MKII features Blackstar's best clean and overdrive tones, including sounds inspired by classic American and 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 HT20RH 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.

I came upon a 212 cab with Vintage 30s and wanted to get a gig-worthy head for it without breaking the bank. Blackstar answered the call! The 2/20w capability allows me to practice and record as well as achieve needed stage volume. The voicing options are great for vintage/modern versatility for cover gigs and the built in reverb and included foot switch made it a no-brained. Very satisfied.



Happy to have!
