Ashdown C210T-500 Combo
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".

Ashdown C210T-500 Combo
Exactly the same as the Ashdown ABM of the same power. What to remember: a combo that has a lot of potatoes, very friendly, lots of opportunity and look good rock'n'roll.


Simple the ranks of each knob and fader configuration noted above.
It is one of those amps or actually "some of the setting" the sound is good. The buttons serve only to give the color you search even if ampegisante trend is noted.

Integrated DI not terrible, I opted for a passive Radial I plug in the effects loop for the coloration of the preamp.


For all styles! I especially think it's the musician and the instrument will or will not be able to adapt to a style that amp.

I use a Musicman Stingray 3 eq and sometimes with a precision "vintage" (lag) that I totally changed (new electronics, micro Bar Knuckle)

Never use the octave (sub harmonic on the amp) is really disgusting! For the rest it is very versatile, the compressor helps a lot!


I use it for 2 years and I am delighted. Too bad it costs so expensive (I got it for a very good price in fact) because in reality the ABM version is exactly the same (apart from HP) so for the price difference I'd rather take the ABM.

The pros:
- Preamp tube
- Compressor
- 7-band eq

the -:
- Weak enough
- Very very expensive (between 1800 and 2500 €)
