One Holy Combo Amp to Serve Them All

Everyone from jazz box architects to 8-string sweepers will find a lot to love in the Blackstar St. James 1 x 12-inch 50-watt Tube Combo Amp. As Blackstar’s lightest and most innovative tube combo amp available, the St. James is tailor-made for studio and stage musicians seeking an all-in-one solution for everything from DI recording to live performance and beyond. St. James combo amps are constructed from candlenut plywood, reducing the weight significantly while maintaining the look and feel of a boutique amplifier. Its two channels are perfect for guitarists seeking crystal cleans and overdriven tones, relying on a single Celestion G12Z-70 “Zephyr” speaker to deliver this amp’s sweet sounds. Swapping between the two channels is a breeze as well, with onboard toggles and an included external footswitch to meet your switching preferences. Best of all, the St. James comes stock with onboard cabinet simulation and power reduction — adding features like this to your rig often comes with a substantial price tag, but that’s not the case here! Incredible sound for any situation is yours for the taking with Blackstar’s St. James 1 x 12-inch 50-watt Tube Combo Amp.

Two channels of wide-ranging tone

When Blackstar set out to make the St. James series their most versatile and portable amps to date, they didn’t cut any corners with regard to delectable tone. Two channels take you from glassy cleans to vintage crunch and even gut-punching grind, with channel and voicing selector switches around the front for easy toggling and a footswitch input around the back to swap channels with the included external pedal. The 6L6-equipped model brings additional heat to handle today’s most aggressive genres while staying sonically balanced.

Highly demanded extra features built right in

Rather than force you to spend potentially thousands more on additional cabs and an attenuator, Blackstar loaded their St. James combo amps with top-notch cabinet simulation and power reduction. Dubbed their Cab Rig Output, the St. James’ cab sim technology arms you with three different cab sim options and your choice of balanced XLR or line out/phones output to run your tone straight to an interface or mixer as well as USB for running to a computer — no cab required! City Music guitarists always appreciate built-in power reduction, with options for 50-watt, 2-watt, and Sag (softer, more vintage sound) operation delivering plenty of volume for the stage while keeping the roommates happy at home.
