actually wattage doesn'T influance the volume necessarly... it's a great indicator of it though.

but yeah, you're right.

How so? More wattage = louder amp. It's exponential though, so you need to double the wattage to notice a difference. Even if the difference is small to perceive, it's still there - and it's certainly perceivable from 15w to 100w.

more watter means more headroom for more volume, it'S not a direct link though.

which is why a 50 watts single rectifier will be much louder than a 150 watts line 6 Smile

Hmm, never thought about that. Solid state amps are quieter than tube amps - great now I wanna know why. Thanks for making me learn, dick.

Are Tube Amps louder than solid state amps of the same power?
Yes and no. If you put a power meter on the output of a tube amplifier and a solid state amplifier that have been matched for total output power, then the meter will read almost exactly the same power for equivalent drive conditions - so in this sense, the answer is no, they are not louder. However, if you LISTEN to the two amps, you'll find that the tube amp does indeed sound louder to your ears, in opposition to what the meter is telling you. Why?
It's tied up in the sensing instrument - that is, your ear. The way the human ear works is that it is very sensitive to the harmonic content of a sound. A tube amp is less linear (that is, has more distortion) at signal levels below clipping than a solid state amplifier. The distortion will increase slowly, and then more rapidly as the amp starts to clip. In fact, the distortion increases so gradually and is of such a benign nature that the onset of audible distortion has no easily defined threshold. The solid state amplifier on the other hand has no such gradualism. It is almost perfectly non-distorting right up to the point that it clips, and then it clips HARD. It's easy to hear the threshold.
This sudden onset of distortion is also composed of relatively harsh sounding distortion, not like the subtle second and third harmonics of the tube amp. The human ear hears the sudden harsh distortion as clipping and harshness. It interprets the low order distortion of the tube amp as a louder sound, not as distortion. In effect, the tube amp fools the ear into thinking that its early distortion is more loudness. They therefore sound louder or more powerful than the actual measurements show are really there.


Science is neat.

when you overdrive a power tube it will output more than its rated value. Not only that but it sounds good to overdrive tubes, so everyone does it. When you overdrive a solid state amp the clipping sounds bad.

Yes, I knew that, but it doesn't explain why a tube amp will sound louder even when the output power of a tube and solid state amp are identical.

I have an old ass akai reel to reel from 1969 that's all tube. Sounds pretty sweet with the guitar - I should build a tubescreamer to the original specs and try it out.

no, not necessarily.

same wattage:
