Overview

The Blackstar HT Studio 20H amp head offers huge versatility for home, rehearsal, or studio use and can be used with a variety of cabinets. The carefully voiced preamp coupled with a cathode-biased EL34 power amp, provides the user with the ability to create wonderfully lush valve tones. From pure boutique cleans, to mild overdrive that cleans up by backing off the guitar volume control, up to highly saturated distortion, this tube amp head does it all.

The Blackstar Venue HT Studio's Clean Channel provides a wide range of clean and moderately overdriven tones. The voicing is typical of many 'boutique' style amplifiers with a ringing Class A type performance. The overall character may be adjusted with the Tone control from dark and warm through to bright and sparkling.

The HT Studio 20H Overdrive Channel is characterized by a tone that's high in gain, but lacks any of the detached top-end 'fizz' often found in many similar designs. This is a result of unique preamplifier and power amplifier shaping techniques. The overdrive cleans up beautifully as the guitar volume is reduced, so even at the most extreme settings, the Overdrive Channel on the Blackstar amp head remains natural sounding.

The HT Studio 20H Overdrive Channel also has its own highly flexible EQ section providing a variety of overdriven tones. Blackstar's ISF (Infinite Shape Feature) control represents a major step forward in tone-shaping flexibility. The ISF control shifts the response of the 3-control tone stack between a US-type response at one end, and at the other a UK-type response. Between these two extremes the amp head provides an infinite number of alternative tone choices that would be otherwise unavailable.

The Blackstar HT Studio 20's 2-channel design has been optimized for either preamp or power amp overdrive, or a combination of both. The carefully voiced preamp and cathode-biased dual EL34 power amp configuration provides the user with the ability to create wonderfully lush tube tones. From mild overdrive, that cleans up by backing off the guitar volume control, to highly saturated distortion, this amp does it all.

The HT Studio 20H tube amp head also features a completely natural sounding digital reverb, which is outstandingly musical on both clean and crunch tones and raises the benchmark for guitar amplifier specific reverb design.

I had a Blackstar HT-5 at one point in time and really enjoyed it. The only issue I had with that amp was stage volume. Some of the places I play do not have floor monitors so the 5 watts the amp put out could not cut over the drummer. Everything else about the amp I loved. Moving forward some time...Blackstar announces they are expanding the Venue series to higher powered alternatives. Some of which have expanded channel settings. I picked up the Ht-20 head going off of the love I had/have for the HT-5 and it does not disappoint. While the 40/60/100 models all have additional channels and/or voicings, this 20 is just like the 5 only louder. Features: For an amp of this cost I feel as though it really delivers in the cost/return department. Two channels with a series effects loop, footswitching, ISF feature.... Quality/Reliability: I have owned 3 different Blackstar amps and never had a single problem with them. I expect this to hold up very well through many upcoming shows. Look/Feel: Sleek black design with some decorative piping on it. Looks nice sitting on whatever cabinet you decide to use. Final thoughts....one big factor that people sometimes overlook in an amp head is the cabinet and speaker choice. These amps are capable of producing more gain than there smaller counterparts and take to pedals very well. I do not find much use for the clean channel (due to my style of music played) but it does its job. Most people do not think of Marshalls (makers of this amp are former employees) for their clean sounds. Thanks for the read. Hope it helps in you deciding to make a purchase.

Great amp. Great sounds and so far after 20+ hours seems to be reliable. Marshall based owners that are giving a different spin on the British amp builders/designers.
This amp has 2 channels, clean and OD. Even though the clean only has a ton and a volume knob, it really does give a great Fender sound with my Baja tele. Turn the ISF knob all the way to the right and it sounds much warmer with my SG. All around great channel. Reverb is nice. Not as lush as a pan reverb but still very useable. OD channel is great as well. Marshall to Mesa but can get great blues tones as well. Don't use the EFX loop or line out so I cant really comment on that. Using this with the Blackstar 1x12 cabinet and love the tones I am getting. Tried this head with the Artisan 2x12 and found the V30's a little heavy on the mids.
Built well. Looks nice and seems that this will hold up for a long time. I don't like the tube layout in the back. The tubes are board mounted and are recessed under the chassis so if you pull out a 12AX7 for a swap you better look to see which way the pins are! This can be a real pain as there is not a lot of room to work with. The layout could have done better even on a budget amp like this. Built in KOREA not in UK. Only designed in UK but looking inside it seems to be put together well.
A 2 channel head that is portable with reverb for $500 can't be beat. ISF alone is a reason you should check these out.

    Comments about Blackstar Venue Series HT Studio 20H 20W Tube Guitar Amp Head:

    Basically of every amp I have ever owned, this is the one I would keep. Things I love about this amp:

    - The CLEAN channel. They call it their "boutique" voicing; it's like a slightly less intense Fender blackface. Takes all kinds of overdrive and fuzz pedals, but without sounding too harsh (note: I also own and love a Twin Reverb RI, so I'd like to think this comparison is not totally unfounded). Bonus: tons of clean headroom (unlike most Marshalls).

    - EL34s. Most of the new breed of mini heads have EL84 power tubes, often running in Class A operation. This is EL34s running in Class AB but with cathode biased for the lower wattage. I feel like I can hear a difference here.

    - The Master Volume control works great; it has an even sounding response to it. Unlike the JCM800 2210 I used to own, this thing doesn't go from 0 to 60 just by moving the knob from 0 to 1. You can get great tones at reasonable volumes without a power attenuator.

    How I use it for awesome tones:

    - Avoid cabinets with super bright speakers like Vintage 30s. I use an Egnater 212 with private labeled Classic 80s and it sounds awesome. I bet G12M-65 Creambacks would sound even better.

    - Crank the channel volumes and adjust master volume as need be. This seems to up the current in the preamp tubes and at once brings out both awesome punch and compression.

    - Like a Marshall, crank all the EQ knobs up and roll back treble as necessary. Adjust the ISF knob to taste.

    - Don't go crazy with gain (never more than half-way). Use OD, boost or fuzz pedals in front for times when you do need extra gain.

    To preempt the naysayers/haters, it's not 100% tube:

    - It uses a FET for the phase inverter. Whatevs. Unless you are Eric Johnson, I doubt you could come close to hearing the difference.

    - There is probably also some diode clipping going on. Just got my hands on the new Marshall Mini Jubilee head, which also has diode clipping. This sounds better.

        Very versatile amp. Produces great clean and high gain sounds. For clean sounds, you would need an eq because the eq knobs only work for the overdrive channel. For high gain, it'll sound monstrous with a boost pedal. I'm satisfied with this product

          Comments about Blackstar Venue Series HT Studio 20H 20W Tube Guitar Amp Head:

          I received my 20H from my local music store 3/10/15. Before I took the amp home I had the repair shop replace the cheap Chinese tubes with Russian made Grove Tubes. Wow this little amp sounds great through a 1x12 Marshal cab. This amp is loud for a 20 watt head. There is plenty of headroom for both channels. My original plan was to use this for my practice amp at rehearsals, but it has plenty of power to use it at gig's as well. Since I mic my amp at all gig's this amp can be used at larger clubs as well. The clean channel is just that, clean. The overdrive channel is very versatile. It is designed to go from U.S. to U.K, but I don't really hear Mesa Boogie tones. What I do hear is a Marshall tone that Rocks. As I moved the IFS control counter clockwise it noticeably changes the tone of the amp, in a good way. I can't say how good the amp is made, since I only had a day, but it seems to be solid.

          The reason I purchased this amp is because it has an effects loop and it has simple channel changing controls. I use a GT-100 for my effects processor and amp channel control. I use the 4-cable method to get the effects in the right place within the amp. it does that for me and it is considerably lighter than carrying a heavy combo around. Now I can take this little amp with a 1x12 cabinet and I'm set to go.

          I would positively recommend this amp to anyone looking for a 20 watt head, just replace the tubes with quality tubes and you will be happy.

              Comments about Blackstar Venue Series HT Studio 20H 20W Tube Guitar Amp Head:

              I not a professional musician doing this for money. I have however been playing since I was 13 and now I'm 47. Playing guitar is my hobby and jamming with friends. In the past I had a Peavey Bandit, Crate Chorus (solid state), Carvin SX212, Carvin X100 (212), Fender Hot Rod Deluxe, Marshall DSL401. Currently I have a Carvin X60 combo amp and a Blackstar HT5 head. Now the 20 watt studio.
              I was really impressed with the HT5 head and wanted something in-between 5 and 60 watts. The 20 watter was perfect. Right out of the box it was great sounding with the tubes it came with. Sovteks in the preamp and Rubys in the the power section. Bias was spot on when checked. I changed the preamp to Electro harmonics because I had a set lying around but really didn't have to. Sound change was slight. Ruby tubes in the power section stayed. They sound excellent.
              Ok how about sound? For this price? Very happy here. Cleans are very nice like my Carvin X amp. Very fat sounding. My main guitar is a Gibson Classic Custom SG with a 57 classic hum bucker in the neck and 57 classic plus in the bridge. On the distortion channel it sounds very very good. Plenty of gain for anything but most importantly when you roll off of a high gain setting the tone stays. Does not get thin sounding. Stays fat. Some amps do cleans well (like Fender), some distortion. This one does both well. My Carvin X amp does both well but is now pushing 25 years old and can be a little finicky at times (its old and was used a lot).
              Build quality? Very good. Its 20 watts but was surprised that the amp head has some weight to it. Its not as light as you might think. Thats a good thing. Means they used beefy transformers and good wood in the construction. Should last until the day I croak.
              If your looking for a good sounding amp with a reasonable price I would definitely put this on the list to ck out.
              The one thing that is different about this amp is there is no standby switch. The standby switch is built in to the input jack for the guitar. Unplugging the guitar from the amp input jack puts it in standby. Unplugging from your guitar does not. You just have to move some Heineken bottles out of the way on top to lay the cord up there when going on a break.

              A Wonderful Amp

              Comments about Blackstar Venue Series HT Studio 20H 20W Tube Guitar Amp Head:

              Title says it all. Sounds amazing. Loud as hell with a 2x12 cab. Great range of drive, from slight distortion to full metal. Clean channel is very good. Simulated output works fine to a board. The 3 EQs on the drive channel are great. My only cut is that it has only one EQ knob for the clean channel, although it is pretty useful.

              Comments about Blackstar Venue Series HT Studio 20H 20W Tube Guitar Amp Head:

              This amps sounds amazing. I had to order this online since my local guitarcenter didn't have it at the store. When it came into the store I compared it to the Marshall DSL15 head (Same price) and I only played 3 chords before I turned it off from how bad it sounded. The Blackstar sounded absolutely astounding though. Like what a Marshall should sound like. It reminds me of a Mesa Boogie Mini Rec. It does the Classic rock tones through to the heavey metal tones. The ISF is an amazing feature and no matter where it is, it sounds pretty dang good. I took this one over the Orang OR15 also, due to it being $200 cheaper and has a much wider range of features and abilities. This amp is PERFECT for studio recording and gigging! ive been playing for quite a few years and recording in my home studio for about as long and i can tell you that you won't be disappointed. Plug it into a Marshall 1960 JCM900 cab and it sings. Get this amp now!

              Comments about Blackstar Venue Series HT Studio 20H 20W Tube Guitar Amp Head:

              First let me say right off .. When you read a review and it starts off with " I play worship.." or anything like that.. quit reading... Its like asking a drivers ed student to rate a race car. (out of the way) The ht20 is great for the price.. I will not go over the good stuff thats been said before.. the 20 has a better clean than the HT-5 (actually if you want clean avoid the ht5 or ht5 reverb.. both break up way too early. the 20's got a very nice clean with lots of headroom.. the negative to this is its got a single knob tone control.. so you are stuck with whatever the single dial has to offer.. if this amp weren't so good in every other regard I would knock off 1.5 but at this price you forgive it... The other thing and it has been mentioned but is also annoying is the lack of a standby switch... I really have a problem just letting an amp idle at full power when its not being used..

              At 20 watts the HT20 has plenty of headroom as to keep up with a loud drummer. With this amp you can turn up the volume to drive the tubes to get a good smooth tone. With other higher watt beasts you have to keep the master volume down thus copromising tone and quality and sometimes sounding like a bumble bee. The effect loop is top notch and lets the true sound of pedals shine threw without coloring the signal. In the past years I have had many amplifiers and this one ranks in the top.

              I am very pleased.
              Let me add I play G&L S500 w/Jeff Beck/Seemore Duncan pickups and PRS CE24 both 1995 SOUND EQUALLY GOOD ( That ISF control does work )
