Mark Gooday from Ashdown presents the CTM-15 tube bass amp head, demonstrated with the help of renowned bassist Jaquo III-X. Enjoy the demo, then check out the CTM-15 in more detail at the link above! - Hudba
Why does Robert De Niro have a British accent in this video?
And how come Ice T isn't talking at all?

Ashdown had a big budget for this video
"theres something about the way they work that makes them louder"
Mark, i know your an extremely knowledgable dude, you designed the damn thing. by all means, explain away! us studio bassists are interested :)
Transitor amps tend to function in the clean gain region. If their power output crunches, it will generate 3rd harmonic distortions. It's what we call "sterile" or "cold" -... sounding.
Tube amps tend to produce pair harmonic distortions when they reach their distortion point. What we call "harmonic" - ...sounding.
By design. Transistor amps have a whole lot of usable volume and perform well since the start of their gain. When tubes, by design, tend to need a "kick" to wake up. So they will already be pretty loud, when enough current is sent through them.
Add to that, that a normal speaker tend to have sensibilities going from 89dB to 99dB 1w/1m. Meaning that the speaker, having only one single watt coming to him, will transform this in 99 dB in 1 meter distance. On the noise scale, this is the spot where you would find "concert" or "loud factory".... It's pretty massive loud. So a 15 watt tiny tube amp will already be a lot from the point of it's loudness.
But... there is one hidden factor, that isn't mentionned there. It's that a 15w amp has a limitation in the heft (sorry, not englishman), it can give to a sound. Generally, bass speakers are functionning with lots of speakers, needing good current stability and lots of current in the output. 15w can fall a little bit short in this matter. Good example are vintage guitar amps. The 18w marshall's are great for classic rock tones, they will not have a solid bass fundament, but if you take the 200w Major marshall, it literally kills babies and has rock solid bass. This is electric physics that are too high for me, but, if I simplify, this works like your 5L V8 engine or your I4 1.4Tsi engine. Both brings you forward. But both will have different behavior in their limit. -> this explains also why the transistor bass amps are so popular and affordable. Since the incoming of class D technology, it's allowing cheap and powerful bass amplifiers to be made.
Clean tone is loud enough for small venues?
Sounds quite good to me, I think $500 is a bit to much, at least for me. If I had the money though I'd get this and a 2 12' cab and use it the studio all day.
