Blackstar has made a huge splash on the amp world in recent years. They have made great sounding fantastically priced amps for the masses. The price is what is so amazing to me. The amp sounds so very good and to keep their prices for a multi-channel combo like this under $1000 is remarkable. Blackstar has effectively used a great design as well as superb marketing which has enabled them to produce a great quality and sounding amplifiers. Many touring and professional artists all over the globe are now turning towards Blackstar for their guitar amplifier needs. The have successfully taking a huge niche in the market over the last few years. To add to their prestige they have included a whole line of distortion pedals as well.

This amp is a versatility dream come true. This amp has four channels and within those four channels eight different modes. You also have the famous and exclusive ISF control knob which give you even more control over the channels and top it all off with a speaker emulated output. I almost forgo that it has midi built in for switching all the channels with your rack effects.

This amp has so much to do that you think it wold get tire before you would. It has four channels and within each channel two different modes. So the clean channel is nice and chimey but also cab get dark and bulky. You get a plexi clean tone which not one I would like to emulate, but they have it. They also have a class A type mods for the clean channel. This is more of a Vox style clean which is much better. Next you have the crunch channel with two different modes. You get a regular crunch and then a super crunch mode for new modern music. The third and fourth channels are similar in their modes. Tye both have high an low high and low out put damping. You can get this amp all the way down to 10 watts. That is a huge drop in power and allows you to play quieter at home or the office.


You can score one of these amps new for right at around $1750. Not a bad price for an amp that has this much versatility and functions. Some amps that have similar features would fetch well over $3000+.

I would recommend this amp to anyone who needs and ultimate switching amp that can have more versatile features and tones than you would know what to do with. It is an excellent buy for the money.
