When entering the world of audio interfaces, Blackstar wanted to offer a solution to musicians that answered many of the much-requested improvements they wanted when using audio interfaces. Through extensive research, we consistently pinpointed three primary challenges encountered by music creators when recording guitar directly through an interface.
- Poor feel and response
- Setting guitar input levels
- Ease of use
The POLAR 2 interface answers all of these challenges and excels beyond those hurdles to provide an incredible all-in-one solution to recording guitar.
Firstly, Polar features FET instrument inputs. The FET inputs give ultra-low noise and high headroom, which gives the recording musician the best sonic foundation for guitar tone, but we didn’t just include FET inputs, we took itone step further with the addition of the “Enhance” switch. When Enhance is switched on the instrument input, it engages a unique circuit that’s been meticulously designed to mimic the input stage of real valve amplifiers—including all its non-linear behaviors and characteristics. The “Enhance” switch restores the touch, the feel, and the response of playing through a real amp.
Secondly, Polar solves the issue with setting levels. Other interfaces often digital clipping due to the dynamic nature of guitar DI signals. With “Enhance” on, POLAR’s innovative input stage will never digitally clip. No more ruined recording takes, no more hassle or confusion around setting the ‘correct’ levels. POLAR allows the musician to drive the interface like the preamp section on a real valve amp.
Recording is made easy with Polar 2. By engaging the “Enhance” feature on the microphone inputs gently lifts the top end of your signal to add just the right amount of air and clarity that sounds great on vocals, acoustic guitars, and more. The microphone preamp has been based off one of the most renowned vintage studio preamps.
POLAR 2’s ultra-low noise and high headroom accommodates for a wide range of microphone and instrument types, empowering the musician to achieve studio-quality recordings in any environment. Included with all POLAR2 units is the POLAR Control app, which allows for fine-tuning of levels, panning, routing. The FET inputs combined with the Enhance switch make it really easy to get an amazing guitar tone. You don’t have to worry about any external hardware, no fancy DI’s—all of that is built right into POLAR.
With its innovative features, impressive headroom (24V), incredibly low noise floor (115db), powerful headphone amps, bus-powered capability, and approachable design, Blackstar’s POLAR 2 is easily the go-to audio interface for anyone that wants to play and record guitar. The POLAR 2 interface was created through the processes of Human-Centred Design, to help create a user-friendly solution to get musicians back to focusing on the most important part: the music.

Blackstar POLAR 2 | The USB audio interface designed by guitarists for guitarists
Firebirds came stock with a solid G-logo tailpiece, although Bigsby vibratos were often added.
It also has a personal connection. A guitarist in the band I toured with in the 1980s played a Jet Firebird from this batch extensively, but later sold it. At a decades-on reunion, it was sorely missed, leading me to obtain this one to provide the same “Great Gretsch Sound,” as the company’s ads trumpeted, and style.
Gretsch’s so-called “Jet Stream” models have been one of the company’s enduring creations. Spurred by Gibson’s 1952 Les Paul, Gretsch replied with a guitar of similar size and layout, but different construction. The single-cutaway Jets appeared in late 1953. Designated as solidbodies in the catalog, they were actually semi-solid, built on a mahogany body hollowed out from above and capped with an arched plywood top. This reduced weight and gave them a different sound and feel.
“Designated as solidbodies in the catalog, they were actually semi-solid, built on a mahogany body hollowed out from above and capped with an arched plywood top.”
By 1955, Gretsch fielded a line of Jets: the black-topped Duo Jet and Western-themed Round-Up were followed by the sparkle-top Silver Jet, the red-over-black Jet Firebird and Western orange 6121 Chet Atkins solidbody. Several sold well through the ’50s, but by the turn of the decade, sales seemed to slump, as with the Les Pauls that inspired them. In 1960–’61, Gibson redesigned the Les Paul into a slim-sculpted double-cutaway. In late ’61, Gretsch restyled the Jet body into a symmetrical double-cutaway, retaining the semi-solid construction while persisting in calling them solidbodies. The new catalog announced: “Out of this world.... Find yourself soaring through musical space and time … the epitome of solidbody construction.” The revised Jet Firebird listed at $325, soon raised to $350. The actual transition occurs in a batch bearing serial numbers in the 420XX series. At the time, Gretsch numbering usually allotted 100 pre-numbered labels to a production-year model, with all Jets lumped into one batch. The label is inside the control cavity; the serial number is also hand-etched onto the back plastic cavity cover.
Jets from 1961 retain the main features of their late-1950s predecessors: twin Filter’Tron humbucking pickups, master volume on the lower cutaway, individual pickup volumes on the lower quarter with the pickup selector and tone switch (aka “mud” switch) on the upper, bass side. The Jet’s evolution happened rapidly, moving through three stages over this one batch. The first 30 to 40 420XX examples are still single-cutaways. By 42043, the double-cut body appears, showing a notable eccentricity: the pickup selection and tone switches arrayed across the upper body in a straight line above the pickups, to the rear of the prior position. Unfortunately, this meant players could easily hit them while picking, inadvertently changing tones in mid song!
Note the chips in the headstock wood—signs of an earlier alteration of the tuning pegs, now restored to vintage spec.

Shortly after this Jet Firebird bearing the number 42057 was made, the switch array was moved forward to the upper horn, mounted at an angle. This change appears by 42064, suggesting only around 20 to 30 of these first-style double-cuts exist. Known examples are mostly Duo Jets, with a few Jet Firebirds and a couple of rare Sparkle Jets. These also lack the 1961–’62 standby switch fitted on the lower bout. All came stock with a solid G-logo tailpiece, although Bigsby vibratos were often added. The next Jet batch introduced the top-mounted Burns of London vibrato unit as a stock fitting and an upgrade to gold hardware. While the double-cut body gave the Jets a new, modern look, it apparently did not improve sales. The balance suffered from the upper strap button moving back several inches, but otherwise they felt and sounded pretty much like their predecessors. This model is most associated with AC/DC’s Malcom Young, who powered the band with one right from the beginning, with that particular guitar heavily altered along the way.
The company’s Filter’Tron pickups have always had their own distinctive bark.

This 1961 Jet Firebird survives in more original condition. The bridge and tuners previously went missing but have been restored to original. A driver’s license number is etched on the back of the headstock, and chips on the peghead face remain from the tuner alteration. A strap button was added to the heel, giving a better balance point. The playability is excellent and the Filter’Trons offer the classic ring and crunch, accentuated by the chambered body. The neck is slim and round-backed, with a bound-ebony fretboard inlaid in the company “neoclassic” pattern, retaining the original frets. Not being a heavy-handed strummer, the eccentric switch location has never bothered me. While in the early 1960s these pseudo-solidbodies seemed to fade from popularity, for me, this early example of Gretsch “jetting” its way into the 1960s remains a solid favorite.
