Blackstar St. James 100 Head

Highlights

• 100 W all-tube amplifier head — powerful enough for full-band gigs, yet versatile for studio or rehearsal use

• Dual-power tube configuration: 2× 6L6 + 2× EL34 — choose 6L6 mode, EL34 mode, or blend both for the full 100 W “all-tube” experience

• Four foot-switchable channels with multiple voices (Clean, Crunch, two OD modes), giving a wide tonal palette from clean to high-gain distortion

• “Cut” selector for shaping high-end frequencies — from bright and aggressive to warm and vintage — allowing flexible tone tailoring

• Built-in reactive load, effects loop (series/parallel), digital reverb, USB audio out, XLR CabRig output, and speaker-emulated outputs: ideal for recording, silent practice, or direct PA feed

Key Features & Benefits

Flexible Valve Power for Multiple Styles
The dual-valve design (6L6 + EL34) gives flexibility in tone — 6L6 for tight, punchy modern tones; EL34 for classic British-style warmth and grit; or both together for full-bodied power and versatility.

Tonal Versatility via Multiple Channels & Voices
With four foot-switchable channels and several voicings, you can shift from pristine cleans to crunchy rhythm or saturated lead with a tap — useful for playing across genres or switching between clean and overdriven passages mid-set.

Modern Connectivity & Recording-Ready Features
Built-in reactive load, CabRig speaker emulation, USB and XLR outputs make recording or direct-to-PA performance easy. Effects loop plus reverb give flexibility to add pedals or ambient effects without needing extra gear.

Tone Shaping on Your Terms
The “Cut” selector and multi-band EQ let you sculpt tone precisely — tailor the high-end, adjust mids/lows, and dial in the amp’s personality to suit your guitar, style, or room acoustics.

Power Reduction — Great for Home & Studio Use
Lowering output down to 5% lets you enjoy tube amp dynamics at lower volumes — ideal for home recording, practice, or late-night sessions — without losing the characteristic valve response.
