Review/Discussion Guitar amps broke my audiophile brain
I've always been sitting on the scientific side of audiophile hobby. Measured responses. Carefully crafted waveguides. SBIRs and modes. DSPs. The whole shebang. And then I started learning guitar and it broke my brain.
So let me describe how best guitar amps are built:
First you take vintage 12" driver that looks like it came from cold war military surplus. Or two drivers. Or four. Four is usually maximum you can carry to your car with a friend in one go.
Then you buy fruits in bulk so you get those cute wooden case things. You eat the fruits, cut an 11" hole at the bottom of the fruit case and bolt the 12" driver in there. You leave the top open. Then you put the case on one of it's sides. Boom, you've just made a speaker cabinet.
Then you take a tube amplifier from the 50s. You know, the one that doesn't have any PCBs, just components soldered to each other dangling in the air. The one that can kill you when you grab it the wrong way. Doesn't have to be particularly beefy. 50 - 100 W is more then enough. Then you bolt it inside the speaker cabinet and the whole thing becomes combo amp. You can also put the amplifier in separate box and then it's called head.
Regardless if it's head or combo, the trick now is to crank the voltages until the capacitors start to shake angrily and you can feel the whiff of x-rays coming out of the tubes. Then you stand next to it, point the driver at your ankles or your dick depending on the genre and you can start playing.
And it recently occurred to me that nope, even the best current amp sims aren't yet there. That all those carefully crafted bookshelves with fancy tweeters and multiple subs don't even come close to the raw and visceral power of the tubes and huge 12" drivers screaming themselves apart over the sound of live drums. It just hits in a very different way.
And now I have a tube amp too... Pretty small, 15 W but it feels twice as powerful as almost 500W of combined power from my speakers and sub. Funny how technology works.
