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.

This thing is awesome! Great overdriven tube sound that will clean up nicely or give you as much crunch as you want. The clean sound is actually really nice- clear and sparkly. The drive side is flat out great, has a very vintage voice when set to 3/4 or hard crunch when turned all the way up. Turn it down to 2/3 and it has a nice "rock" tone and put a dumble style pedal juiced up for when you need a boost- awesome combination. Super portable and built rock solid. I know it will always get looked down on because of size and price, but this thing is just flat fantastic.
