Description

Unleash your sonic creativity with the Blackstar Series One 100 100W Tube Guitar Amp Head. This powerhouse amplifier is engineered for musicians who demand versatility and precision in their sound. With its 100-watt EL34 power stage, the Series One 100 offers an expansive palette of tones, from pristine cleans to bone-crushing crunch. The amp's dual-channel design, featuring 4 footswitchable modes, gives you the ability to seamlessly switch between a variety of sonic textures on stage or in the studio.

At the heart of this amp is Blackstar's proprietary Infinite Shape Feature (ISF), a groundbreaking tone control that shifts your sonic signature from a tight, aggressive American sound to a warm, mid-rich British vibe. Whether you're chasing classic rock tones or modern metal aggression, the Series One 100 has you covered.

The Dynamic Power Reduction (DPR) feature allows you to dial down the output from 100 watts to just 10 watts, making it perfect for both intimate venues and home practice without sacrificing tonal richness. MIDI switching capability further enhances its flexibility, allowing you to integrate your rig effortlessly with external effects processors.

With its meticulously designed channels, the Series One 100 offers a Clean channel with Bright and Warm modes, and an Overdrive channel with both Crunch and Super Crunch modes. This ensures you have a comprehensive suite of tones at your fingertips, all with the warm, organic feel of tube-driven sound.

Setup and maintenance

  • Power tube failure often causes random volume changes; replacing them early can prevent further damage to other components.

    Source
  • Cleaning the master volume pot and 'send and return' jack switches with contact cleaner can resolve volume fluctuation issues.

    Source
  • Regular power valve replacements are recommended to prevent damage, as older valves can cause HT fuse failures or transformer issues.

    Source
  • Using a fitted cover is highly recommended to protect the amp from dust and damage, improving longevity and maintaining better condition.

    Source

Features and functionality

  • The Dynamic Power Reduction feature's settings may not influence volume issues, indicating a potential technical fault requiring professional assessment.

    Source
  • Blackstar's lack of third-party repair support can lead to costly repairs, as proprietary ICs may require entire PCB replacement rather than individual component fixes.

    Source

Use cases and applications

  • Volume fluctuations have been noted during wedding performances, affecting live gig experiences.

    Source

User experience

  • Despite random volume changes, repair costs were manageable due to uncommon connection issues, offering reassurance for potential buyers.

    Source
  • Owners suggest using an overdrive pedal to enhance the Blackstar's distortion, especially for metal genres like thrash.

    Source

Comparisons

  • Blackstar amps are often considered less repairable than Marshalls and Engls due to proprietary components and lack of schematics from the manufacturer.

Critic Reviews

Blackstar Series One 100 Amp Review - Premier Guitar

premierguitar.com

The Blackstar Series One 100 amp head is a versatile powerhouse offering a wide range of tones from clean to metal, thanks to its innovative ISF and DPR features. The ISF control allows seamless transition between American and British voicings, while the DPR ensures consistent tone at any volume. The review praises its tonal flexibility and value, though notes a slight volume drop when switching from Crunch to Super Crunch mode. For those seeking an amp with diverse sound capabilities rather than a signature tone, this amp is a strong contender.

Back in 2008 when Blackstar was still in its infancy Blackstar sent Adrian Smith a HT-5 mini stack. Adrian then went on to use this and a Series One 100 head to record some of the guitars tracks on the album The Final Frontier. When it came to recording Iron Maiden follow up album The Book of Souls in 2014, upon request, Blackstar sent Adrian a Series One 1046L6 and a 104EL34 to the Guillaume Tell Studio in Paris, France. As well as using both of these amps to record some of the guitar tracks on the new album, Adrian wanted to get the sound he got in his home studios. When asked by Kevin Shirley the producer what he used Adrian replied, ‘The Blackstar HT-5’. So on a weekend trip home to UK Adrian brought back his trusty HT-5. Adrian used the powerfully fitting tone of the HT-5 to help record the rest of the album.

"We use Blackstar amps live. I use the S1-200 and Anders uses the S1-100. The Mesa rectifier is a nice amp, but for us it's impossible to make it sound right without adding another amp in the mix, like a Blackstar or a Laboga. We both use boss stuff for our FX, Anders uses GT-10 and I'm using GT-pro (Rack mount). We have filmed a nice "gear walk through" that will appear on the new DVD." Jonas Renske

Ryan uses a blackstar series one as his main amp sound. He uses this in conjunction with his line 6 helix. Any high gain tones are from his amp, but any clean, crunch or effected tones are run through the helix. the helix bypasses the preamp of the blackstar to run its tones. this way allows him to get the tones he need with the feel of a real amp
