Studio Role Description

A Studio Blending Amp: Bedroom Amp #1:

The “Bedroom Amps” are named for their low power, bedroom quality, tones.

The Blackstar's role is for a “British Marshall” tone blending tube amps with the Stage Amps.

Bedroom Amps are fed by a common tone-shaping pedalboard and distributed using a two channel BBE Sonic fed by a JHS active ABY distribution switch.

The Stage Amp pedalboard only uses “Wet” and “Drive” pedals:
• Gain Staging Compressor
• Transparent Drives: Klon Centaur clones
• Soft Clipping Drives
• Hard Clipping Distortion
• A “De-Tuning” Modulation
• A Dual Delay & Reverb

The final stage is a pair of JHS Clover preamps for amp input gain staging and a pair of LPD signal buffers to ensure a common high-quality signal is sent to the two amps.


Like all amps in Blackstar’s HT Venue MkII series, the HT Studio 20R MkII is a powerhouse.

It’s packed with all the tones you’ll ever need.

Experience truly boutique tone from the HT Studio 20R 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 20R MkII is ideal for your rehearsal space, studio, or anywhere where premium tube tone is required.
