Packed with Tone, Loaded with Features

Like all amps in Blackstar’s HT Venue MkII series, the HT Studio 20RH MkII is a powerhouse — it’s packed with all the tones you’ll ever need. Experience truly boutique tone from the HT Studio 20RH MkII’s updated clean channel, or kick in the overdrive channel for a wide range of distorted textures. And thanks to Blackstar’s patented Infinite Shape Feature, you can dial in everything from inspiring British edge-of-breakup grit to tight and punchy American high gain. Complete with onboard reverb and a speaker-emulated output, the HT Studio 20RH MkII is ideal for your rehearsal space, studio, or anywhere where premium tube tone is required.

Revoiced channels for top-tier tone

When Blackstar hit the drawing board for their HT Studio 20RH MkII, not only did they reference their own amps’ popular tones, but they also wanted to match or beat the tones of electric guitar amplifiers costing up to five times more. Take it from the guitarists at Sweetwater: They nailed it. The clean channel has a clarity and note definition that is rare on amps in the MkII’s price range. Move over to the gain channel, and you’ll take note of how great the sound is throughout the whole range of overdrive. The original HT Studio 20 was an incredibly popular amp. With the MkII, Blackstar beats it.

Patented Infinite Shape Feature

The Blackstar HT Studio 20RH MkII is packed with a massive variety of tube tone, by virtue of Blackstar’s Infinite Shape Feature (ISF). This exclusive feature shifts the EQ curves of the amplifier’s Bass, Middle, and Treble controls. When turned fully counterclockwise, you’ll lend an American characteristic to your voice with a tight bottom end and aggressive middle. Turned all the way to the right, you’ll enjoy more of a British vibe. Beyond that, four different operating modes can be accessed via a pair of Voice switches, unleashing both vintage and modern voicings for each channel.

Loaded with player-friendly additions

The tone of the HT Studio 20RH MkII is well worth the price of admission. But Blackstar knows what players want. And they loaded this already great-sounding all-tube combo with enough features to ensure that it quickly becomes your go-to amp. The revoiced reverb offers more depth and detail than ever before. Nailing cranked tones at appropriate volume levels is easy thanks to the onboard power reduction circuit. Beyond that, the emulated line-out and USB audio output will make you your sound engineer’s best friend.

Back to Blackstar Amps

I used to have a Stage 60 1x12" combo and really liked the options with the channels and voicings. But it broke my back carrying it, so I moved on to all sorts of guitar modeling processors and various other amps searching for tone, ease of use (midi control), and portability. Well I have finally found a tube amp head That has the tone, flexibility, and a relatively lightweight package for transporting. Love the features this amplifier comes with all useful for me. Really digging thIS Blackstar HT20R MK II Head and just like others have said the head phones out put and aux in are really handy for late night or anytime quiet playing, the phone don't sound to bad at all. It takes pedals well too.Great package BlackStar. Oh the first head had some kind of ground loop hum which I think was from some rough shipping and the box wasn't packed in three boxes like the second unit Sweetwater shipped out to me right away. Again the Sweetwater staff took care of my problem promptly before this Holiday weekend, great service and I really love this guitar amplifier.

Terrific Value

I've had this HT20 head for a few months now and all I can say is the more I get to know it, the better it makes my guitars sound! And as a bonus, you don't see many tube heads with phones out jacks, well this one is perfect for playing in the middle of the night. Plug and play, baby!!!

Great versatility and tonal options

Bought this amp from here two years ago. This amp can get you a huge array of tones and also takes pedals very well. I have used the USB feature to record and it works flawlessly and with no difference in the tone vs mic-ing up the cab. Very pleased with the amp. The break in period was about a month or so before it really warmed up so be aware of that.
Rated 5/5

Amazing versatility of tone

Blackstar has made a winner with this 20 watt head. The ISF dial enables the amp to jump between American and British tones and each channel has two voicings. This amp can do it all, but if you want a really good metal tone put an overdrive or boost in front of it.
Rated 5/5

Just an all around great amp

This amp sounds both on booth the clean and dirty channels. It takes pedals well. It can get to bedroom levels and still sound good but it is still loud enough to use with a full band. It has full warm tones. As a bonus it is fairly small and doesn't weigh a ton so I don't hate lugging it around.
