If i got an 30 watt All valve combo, How many watts do i need in a SS to be taht loud ?

For example: Is i have 30 watt Valve I need 75 watts SS?

EDIT: Of course the wattage of 30w SS and 30w valve is the same, as the guy said. Still, there is an obvious difference in volume.

It depends, there are no set rules. 30w SS amplifier with a good speaker can be as loud as 30w valve combo with a smaller speaker. I think that it's safe to double the wattage of the SS, it isn't true all the times but it's a pretty convenient way of calculating it so

15w valve = 30w SS, 30w valve = 50-60w SS etc.

Still, every amp is different so it's not always true. The speaker(s) is/are a very important element here.

Strictly speaking, 30W is 30W, whether it's all-valve or solid-state. The richness (broader spectrum of harmonics) of the all-valve sound makes you believe it's louder. But not by much. I'd guess a 40 or 50W SS amp may sound to you as loud as a 30W all-valve.

i think valves are about 3 times as loud as SS, so you'd need 100 watts SS

but do remember that playing full whack on those amps will probs give you hearing damage

Like i care xD, So Average seen 30 watts valve is like 60 watt ss?

It really depends. I think tube wattage and SS wattage are different. A 50W tube amp is only 3db quieter than a 100W tube amp. Wattage refers to power, not sound. They're not directly related. With tube amps, it relates to the breaking point of the tubes. If you turn a tube amp up, you'll get power amp distortion. The lower the wattage, the sooner you get this distortion. So there's not much difference in how loud tube amps of various powers are. Solid state can use the same power rating. 30W is 30W. But they handle that 30W of power differently. I don't really understand how it works, but it has to do with the way class of the amp.

In terms of sound quality Tube>Valve>SS and same with volume I think. But there isn't an exact ratio like someone already explained, it's different with all amps.

I think it's just that tube and valve amps use the power more efficiently, which means they can get louder and sound better at lower wattage.

Tube and valve are the exact same thing, and they're no better than SS

Exactly. Tube have a better sound than SS and they can get louder and lower wattage. They're very different.

Sorry. Couldn't help it.

Tubes are generally louder than SS. A 5w tube can get as loud as a 30w SS for example. However, in terms of wattage, X watts in tube = X watts in SS.

tubes and valves are the same thing except:

valve = british word.

because back in the day you only had tube. and now everyone wants to recreate those vintage tones, and solid state is out of fashion at the moment. and everyone follows fashion like sheep.
I like analogue Solid State amps that make no effort to be "tube-like", and I'm proud of it...

...A little too proud, to be honest.

Not everyone prefers valve amps. Guys who play jazz or clean blues often prefer the cleans of a SS amp. The sound difference is all about distortion levels. A typical decent SS amp may distort to the specified level, at, for example, 9 on the dial. A similarly rated valve amp might reach that distortion level at 5 or 6, yet have a lot more volume available beyond the rating.
Then you come down to efficiency as a whole which is why a Vox AC30 is almost as loud as a Fender Twin Reverb. That's not saying one is better than the other. They have quite different sounds overall, both of which are popular among a wide range of musicians.

No one likes playing tube amps over SS. They like playing what sounds best to them. With technology today, a SS amp can sound exactly the same as a tube amp and even. 99% of people wouldn't be able to tell the difference between a good modeler and the real amp. But a lot of SS amps are on the cheaper spectrum which give them the impression of being inferior. But there are high end and boutique solid-state amps. They're rare. But a lot of companies won't make a SS amp because a lot of guitarists are stupid and hate innovation. That's why the same guitars that were sold 60 years ago are still the top selling guitars today. But tubes present a limitation. They alter the amount of tones you can get. Ever wonder why a lot of high-gain amps don't have good cleans? It's because of tubes. Tube amps also don't sound very good at low volumes. SS amps don't have those problems. SS is capable of things that tube amps could only dream of. But will SS ever catch on? Probably not.

Tube and valve are exactly the same thing... Tube= Valve... Valve is tube... Tube and Valve= x, x= tube and valve,

Back to the question, I usually say that 30watts of valve pleasure is equal to around 100watts of solid state crankage.

Yep.

In fact, SS is actually a lot better than people make it out to be,

There really isn't an answer. Watts do not equal amount of volume. One tube amp with 30w can be louder than another 30w tube amp.

This is the truth.
An AC30 is EXTREMELY loud. An Epiphone Blues whatever is not anywhere near as loud as an AC30.

True. Look at the Roland JC120, the Fender M-80 and the old pre-MG non-tube Marshalls. This being said I personally prefer tube amps, but I do see the virtue of both.

Anyway, TS, Brian May, The Edge and The Beatles all feel/felt they were loud enough for everywhere from clubs to baseball and football stadiums. It's power compared to a 30W SS amp isn't important, whatever volume you need it'll get done.
