A headphone output and MP3 player input make this amp head perfect for practicing. If you're after that big Orange tone, but want it in a teeny-tiny package, then you want the Orange Micro Terror guitar amplifier head.

I have been playing for a long time and have used a lot of different gear. I still own amps that I bought almost 40 years ago! I am just blown away by this tiny amp! It sounds fantastic!! I love it!
Music background: Guitar player mainly but play several other instruments also.

Micro Master!

You could spend weeks, maybe longer, finding all the tone jewels of this amp! Great tube sounds! I have been impressed with every guitar I plug into this thing, from a Gibson Les Paul standard to a Fender american standard Stratocaster to a Jackson with no tone knob that has a very high output pickup! Great sounds with a nice straightforward control set going direct, while it also seems to really do well with a pedal or two into the front input. All this and you get a headphone output for silent practice, I would feel my money was well spent if I spent twice what this amp costs. If you are on the fence get one!

Awesome amp

Way worth the money
