Orange MT20 Micro Terror Guitar Amplifier Head (20 Watts)

Experience the legendary sound of the Orange Terror series! The Micro Terror brings the iconic Tiny Terror's tasty tones to an even smaller 20-watt amp head.

Following in the footsteps of the now iconic TT15 Tiny Terror, the MT20 Micro Terror crams the same classic Orange tone into an even smaller package. This diminutive dynamo makes a great addition to any practice space or home studio, and can even do its part at gigs around town. Experiment with a massive array of tasty tones from transparent cleans to ferocious overdrive. The Micro Terror does it all in an amp head that can comfortably fit into most backpacks.

Classic Tone: Pure and Simple

Like the rest of the Terror series, the MT20 keeps things simple with just a few onboard controls. Try toying with different combinations of volume, tone, and gain levels to dial in any number different overdriven textures. A single 12AX7 in the preamp maintains the tube-based richness so closely associated with Orange amp heads, while a 20-watt solid state power section provides enough power to pair with a wide variety of cabinets with plenty of vintage British power and crunch. Apart from the signature Orange breakup, the MT20 can also put out plenty of punchy cleans for anything from jazz to indie rock.

One Versatile Little Amp Head

Orange produces an 8-inch extension cab as the standard match for this head, but can also power bigger cabs for larger settings. If you're more interested in practicing at home, a headphone output allows for those late-night silent practice sessions to go till morning. The Micro Terror also includes an auxiliary read more input to plug-in and jam along to your favorite media device.

I just got this head today with the accompanied 8" cabinet and all I have to say is "Wow!". This is NOT a toy. With only three knobs, Gain (tube preamp), Tone (Orange tone) and Volume (Steady-State power amp) this little amp is 100% balls without the BS effects like 3band-EQ, Reverb, EFX loop, etc. I bought this head for recording sessions and I'm overwhelmed by the pure tonal characteristics. Orange hit a homerun in my opinion. The steady-state power amp is extremely clean and the AX7 tube preamp offers biting crunch and tube character. I love the simplicity of the tone control which offers an array of classic Orange sounds. For those players looking for more affected sounds for live performances, this amp MAY fall short (despite having plenty of power to drive a much larger 4x12 cabinet quite easily), however it provides a perfect platform for whatever stomp effects you have in your arsenal. . . . at this price point, you can't go wrong. . . .
