These new Klystron amps are an evolution of the preamps that John Entwhistle collaborated with Ashdonw to develop one of he best bass amps in the world. After several years later Ashdown decided to release a whole line of the Klystron amps in varies heads an combos.

This combo is a 2x10 500 watt combo that will be perfect for just about any gig and band setting. There is enough power here to cut through the mix and still have some headroom. It is great for recording as well with the lineout of the preamp. If you need the extra speaker you can always use the speaker outputs.

I have to say that I am a huge fan of the Ashdown products and this is just another testament of their highly reputable company. This amp sound so tight in the low end with the 10 inch speakers. The cabinet just compliment the tone of these speakers quite well. You can feel the thunderous low end when you are able to dial in the sub harmonics perfectly to your bass guitar.

Just about any guitar sound good through this amp. This amp will compliment what ever existing guitar that you own. I prefer a Rickenbacker 4001 with these amps. I find that the tone of the Rickenbacker is capable of adding to the nature frequencies of the Klystron.


At new you can find these for right around $ 1950. This is a bit high for something like this. So this amp might be out of the price range of a lot of folks. But believe me if you can get your hands on a Klystron you will never look back. They are that good.

I would recommend this to anyone who needs probably the best sounding bass amp in the world. So for you gear heads this is the "one".
