The Micro Terror series of amps from Orange are all tiny little amps with a lot of tone to deliver. So while at your gig you may run through a 1x12" or even bigger at home you want your amp to be as small as possible which is why the PPC108 1x8" cab is so important.

It is worth mentioning that the power supply cable and transformer of the amplifier do not have high quality or durable feel, although you can always buy another in the future without it being a big fuss. If we remove the screws from the top of the amp body, we find the valve dome exposed and some breathing vents. Inside, there is the preamp valve. It comes standard with a JJ ECC83S.I would bet that if you listen to it without knowing what amp it is, you would think it is a higher-end amp. Vox MSB25 Mini Superbeetle

Overall the sound of this amplifier is good, but if we take into account that it costs about 140 euros at the moment, then the sound is very good. I’m happy to say it’s not a toy, even though it may look like one. It has the Orange tone well achieved.Most retailers, including Thomann, sell them both as a bundle, which comes out to just over 200€. From the sturdiness of the construction (which was already assumed considering the brand) to the sound quality (likewise) and even the special touch that the eight inches give it, this is a creamy sounding cabinet in most conditions. The fact it combines so well with the PPC 108 also gives you peace of mind knowing that it has a cab intended for getting all that orange juice. (how is this the first time I’ve said that?). The Micro Terror is not an amp that is particularly known for having a lot of knobs or potentiometers. It is a very simple head that can be used immediately. On the front panel, from left to right, there is the ON/OFF switch with its respective yellow LED on top of the lever.

The knobs are simple, the volume is highly sensitive, and it goes to say that for at-home use, dialing a clean will not exceed mid-settings, and with the maximum gain will not rise much more than six.This curious little piece is a good amp to let rip your guitar skills at home, cheap, and with exceptional portability. Its sound is really up to the level of much more expensive amps, but the few equalization options play against it. The circuitry seems to be well finished except for some components that are a bit crooked or not very straight, nothing that may be a deal-breaker, and also, I suppose that depends on the specific model you get. Usage and Features There are also digital reverb and traditional tremolo effects onboard, providing you with the ability to add another dimension to your sound.

The tone is equally sensitive, regulates bass, mid and treble with just this knob, just like the tone knob on the guitar. It plays with a large palette of sounds, and varying it just a few millimeters affects the tone noticeably. Kemper has opted for a passive system that can work as a flat response speaker or transform like a chameleon into different loudspeakers responding to the simulations or profiles generated from the Kemper Profiler. To do this, new software that is still in a prototype stage will enable an option whereby we can use the Kemper speaker simulations as before, and then the Kabinet will behave like a flat response cab (allowing us to imbue it with that Micro Terror juice). Weighing in at under 1 kilo, the Micro Terror is arguably the most portable amp head on the market. When paired with its matching PPC108 cabinet, the Micro Terror’s Aux Input and Headphone output make it a perfect practice partner, small enough for even the most cluttered sideboard. The Orange PPC 108 is as tiny a guitar-box as you will find. If it wasn´t for it´s rich orange color and the nice "old-school" decals, no one would even care to take a look at it.

Generally when calculating the effective area of a speaker, you take the square root of the number of speakers and multiply it by the (average) size. That comes out at roughly 12 inch for 2 8s. 2 10s would have the bass response in theory of a 15". It depends entirely on the speaker of course, even small speakers can be designed to be really bassy, for example in monitors.
