Description

Blackstar St. James 50-watt Tube Head with EL34 Tubes

The Blackstar St. James 50-watt Tube Head is a musician's dream, designed for those seeking a versatile and portable amplifier. Its lightweight design, thanks to the robust candlenut plywood construction, makes it ideal for studio sessions or gigging. This head is a musical chameleon, with two channels that seamlessly transition from glassy cleans to vintage crunch and even gut-punching grind. The St. James is powered by EL34 tubes, renowned for their vintage-tinged voice that shines in classic rock and heavy metal settings.

This head doesn't stop at delivering superior sound. The St. James amps up the convenience with an in-built Cab Rig Output, providing three different cab sim options and balanced XLR or line out/phones output. This feature allows you to run your tone straight to an interface or mixer, and even to a computer via USB, eliminating the need for an extra cab. The power reduction switch with 50-watt, 2-watt, and Sag operation ensures you can achieve the right volume for any setting, from the stage to the bedroom.

Key Features:

  • 2-channel all-tube head constructed from lightweight candlenut plywood for easy transportation
  • EL34 tubes for a vintage-leaning voicing that's great for rock and heavy metal
  • Two channels for versatile sound options, from clean to crunchy tones
  • Built-in Cab Rig Output with cabinet simulation for studio-quality sound
  • Power reduction switch with 50-watt, 2-watt, and Sag operation for adaptable volume levels
  • USB with cabinet simulation for direct recording to a computer

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Blackstar St. James 50-watt Tube Head with EL34 Tubes.

User experience

  • Owners report recurring afternote artifact noise, especially on bass notes, after a few gigs, despite warranty repairs.

    Source
  • Owners report difficulty in addressing after-note noise issues, even after warranty repairs, with noises reoccurring after a few months of use.

    Source

Features and functionality

  • The amp's power supply, replacing the traditional transformer, is cited as a potential failure point, leading to reliability concerns.

    Source
  • The CabSim doesn't accurately model the custom Celestion Zephyr speakers, lacking a specific speaker choice in the Blackstar CabSim app, affecting simulation distortion points.

    Source
  • There's no straightforward way to adjust the line-out signal without the editor software, complicating sound checks without a dedicated physical knob.

    Source
  • The ISF feature, present in other Blackstar models, is absent in the St. James EL34, resulting in improved tone clarity according to one owner.

    Source

Comparisons

  • The St. James was noted to not cut through a mix as effectively as some alternatives, like the DSL40CR, despite its standalone sound quality.

    Source
  • Owners find the St. James EL34 less dynamic than the Orange Rockerverb MK3, despite both being priced around £1000.

    Source
  • Compared to the EVH 5150, the open-back St. James 6L6 combo sounds flubby on palm-muted metal riffs unless paired with an MXR Custom Badass OD pedal.

    Source

Build quality

  • The switched-mode power supply (SMPS) can introduce EMI noise if not carefully designed, potentially resulting in audio artifacts due to high-frequency switching aliasing.

    Source

Software and compatibility

  • Blackstar limits service information to Korg-authorized shops, increasing repair costs due to circuit reverse engineering for independent repairers.

    Source

Use cases and applications

  • The St. James EL34 is praised for its chimey, Vox-inspired sound but lacks a gain control for the clean channel, limiting versatility.
