CUSTOM WOUND SPLIT COIL PICKUPS | EBONY FRETBOARD | GIGBAG INCLUDED

AN INSTANT CLASSIC FOR BASSISTS PURSUING AUTHENTIC RETRO TONE

The O Bass is the brainchild of Orange Technical Director and lead designer Adrian Emsley, whose inspiration came from his self-confessed love of vintage gear. Having spent a lifetime modifying all manner of bass guitars, the O Bass brings together all of his know-how in a unique and truly charismatic instrument.

Aside from its impeccably sleek lines and shapely aesthetics, the O Bass delivers the goods where it really matters. Plugging in reveals a sound with buckets of personality – familiar, yet somehow all of its own. A custom-wound split–coil pickup bears a very distinctive sonic mojo, with a well-balanced bass response and a bold and defined mid-range. Players with a softer touch will immediately find themselves in Motown territory, with earthy overtones in abundance. Dig in a little more aggressively and the O Bass responds with an infectious harmonic grind that harks back to the birth of rock ‘n’ roll. As Emsley puts it, “It growls like a policeman’s dog!”

The O Bass first made an appearance in an early form as a demonstrator piece at the 2014 winter NAMM show, hidden from public view in the Orange booth. However, having been leaked on a number of videos on the internet, we were inundated with requests to put it into production.

Anybody after a P-type-bass without taking out a second mortgage should really check out this offering from Orange. Read the review.

CLASS AB | BI-AMP INSPIRED | ALL ANALOGUE

Taking the OB1-300’s bi-amp inspired, all analogue design as a base, the combo version really shows off the OB1’s deceptive versatility. Despite its relatively sparse layout, the real beauty of this combo is its ability to go from sophisticated to unhinged at the turn of a knob, or the stomp of a foot.

The OB1-300 Combo houses a new 15” Eminence neodymium speaker in a carefully designed front-ported cabinet, and this configuration is the ideal match for the OB1’s fearsome tonal platform. The two elements combine to offer an immediate attack and a seriously punchy low end, dishing out warm contemporary cleans, grinding vintage grit right up to heavily distorted mayhem. Most importantly, the OB1-300 Combo remains focused at all extremes of its wide-ranging tone controls.

For years bassists have been combining guitar and bass amps to remarkable effect, adding harmonics and layers of overdrive from a guitar amp to their core bass tone in pursuit of the ultimate live sound. This ‘bi-amp’ trend got us thinking… Why drag two amps to the show when you could take just one? The key to the OB1’s unique sound is our footswitchable Blend circuit which adds a veneer of controllable gain and increased harmonic content to the upper registers of the input signal. The lower frequencies and clean signal are left alone, staying warm and clear just as they would be in a ‘bi-amped’ setup.

Depending on where the Gain and Blend controls are set, the possibilities are limitless. Kick in the Blend control to achieve anything from a transparent clean boost, to all-out filthy grind, and everywhere in between.

SWITCHABLE OUTPUT POWER | VALVE BUFFERED EFFECTS LOOP | FOOTSWITCHABLE REVERB

ONE OF THE FINEST VALVE COMBOS IN THE BUSINESS

The Rockerverb Series demonstrates better than anything else that a workhorse amp can be a master of all trades. The original Rockerverb was actually our first ever ‘high gain’ amplifier, with a unique voice that quickly became a firm favourite amongst the heavy crowd. However, its supreme versatility and dependability meant the series has been a mainstay for touring artists and session aces, both on the road and in the studio.

The previous MKII version was voted in the top ten of Music Radar’s ‘Best Valve Combo Amps’ list, but the new Rockerverb 50 MKIII 2×12″ combines over a decade of user feedback with numerous improvements to the design. In a first for the Rockerverb Series, the MKIIIs include selectable output power options to manipulate headroom and volume. This 50 Watt version switches down to 25W in half power mode, whilst the mains transformers have also been upgraded for better low end response and articulation. The MKIII also features the same footswitchable attenuator that has been so popular with users of our Thunderverb and Dual Dark Series amps.

The Clean channel has been revoiced on the new MKIIIs for a more ‘chimey’ response, but still retains the warmth and vintage character of a non-master volume design. The new models now have even greater headroom than previous versions, whilst the valve driven spring reverb now has a more extensive range with a brighter trail. Add to this a host of other hidden refinements and you have the finest sounding and most feature-laden Rockerverb to date.

HIGHLY VERSATILE TWIN CHANNEL DESIGN

The original Rockerverb gained a cult following on account of its iconic high gain tones. The MKIIIs of course continue this tradition, but these amps are immensely flexible. The Dirty channel goes anywhere from clean to crunch to the very heaviest modern saturation, and always maintains outstanding clarity. The non-master volume Clean channel has been re-engineered to take on a more ‘sparkly’ and ‘crisp’ nature but with greater control through a revoiced two band EQ section. The MKIIIs have even greater headroom and volume in full power mode, should you need it, but this can now be manipulated with the amp’s output power and Attenuator controls.

FOOTSWITCHABLE VALVE DRIVEN SPRING REVERB

Driven by an ECC83/12AT7 valve and a custom transformer, the spring reverb circuit in the MKIII has undergone significant upgrades. Brighter and more controllable than its predecessor, this lush spring reverb circuit covers everything from ‘air’ to full-on surf.

FOOTSWITCHABLE ATTENUATOR CONTROL

Cranked amp tones at ‘conversation volumes’. The Attenuator circuit is located after the master volume controls and determines when and how the amp distorts after the preamp stage. This means the overall volume level can be reduced, whilst keeping control over the entire amp’s clipping characteristics. Unlike a loadbox, our design ensures the all-important relationship between the output transformer and the speaker remains intact so, even at very low volumes, the amp remains springy and responsive. Turning the Attenuator control clockwise reduces the overall output level (i.e. increases the attenuation), which can be remotely defeated via a footswitch for a volume boost on either channel for lead lines.

SWITCHABLE OUTPUT POWER

Switching the amp’s output power allows for more control over the headroom and breakup from the output valves. Reduce the output for greater output valve clipping and saturation at lower volume levels. The  Rockerverb 50 MKIII features a ‘half power’ mode which drops the plate voltage on the output valves, reducing the output power to 25 Watts.

VALVE BUFFERED FX LOOP

For the purist who loves their pedals, our highly transparent effects loop is buffered by a single ECC81/12AT7, ensuring an all-valve signal path from input to output.

CELESTION SPEAKERS

The Celestion Vintage 30 is one of the most popular drivers in the world today, and with good reason. A pair of these, housed in a rugged open-back plywood combo cabinet, take the Rockerverb MKIII to another tonal dimension.

“I chose Orange amplifiers because for me, it is the only brand that can provide a vintage tone that sounds really fat ! I always thought that ‘vintage’ lacked thickness… But Orange proved me wrong … I finally found my tone.
My band plays Blues and Southern Rock as well as Hard Rock, so I needed a versatile amp. The Rockerverb 50 MKIII can do it all ! I plug my Bacchus Duke Laura Cox, I set the gain just before noon for a thick crunch tone, and it’s as simple as that.”

OB1-500

LEAVE THE OTHER AMP AT HOME…

For years bassists have been combining guitar and bass amps to remarkable effect, adding harmonics and layers of overdrive from a guitar amp to their core bass tone in pursuit of the ultimate live sound. This ‘bi-amp’ trend got us thinking… Why drag two amps to the show when you could take just one? The result is the OB1 Series of class A/B rack mountable bass heads which take care of this and much more besides.

The key to the OB1’s unique sound is our footswitchable Blend circuit which adds a veneer of controllable gain and increased harmonic content to the upper registers of the input signal. The lower frequencies and clean signal are left alone, staying warm and clear just as they would be in a ‘bi-amped’ setup. Depending on where the Gain and Blend controls are set, the possibilities are limitless. Punch in the Blend control to achieve anything from a transparent clean boost, to all-out filthy grind, and everywhere in between.

OB1-500 shares the same layout and 2U rack dimensions as the less powerful OB1-300, coupled to a full fat 500 Watt output section to move some serious air.

“The OB1 sounds great straight out of the box. You always anticipate having to tweak something but it’s so user friendly.”
