I get more from the way people describe an amp's sound on forums than I do from listening to a demo of it.
Demos either sound good or they don't, but they're more representative of the person's recording skill than the actual sound of the amp. Even then it's still like a Kemper profile, that amp with that guitar, with those pedals, and through that cab and mic.
I still listen to demos, but it blows my mind that people make buying decisions off of them.
This times one thousand.
If any of you watch my channel (lol) you'll see I recently upgraded my audio setup. Instead of recording everything in the room with my iPhone, I moved to using the UA OX or mic'ing my cabinet, recording in Luna, and then editing everything together in DaVinci Resolve. I've done this on the last three or four videos I've done and I'm very happy with the results.
However, one thing I learned is exactly what you so astutely stated: YouTube gear demos are really all down to your recording skills. I can make any amp sound like just about anything with the setup I just mentioned. Different mics, different cabs, different placement, different effects or post-processing, EQing, reverbs, delays, etc. It
all makes a
huge difference. It is
not subtle.
Ask yourself this: when you listen to a gear demo, what is the reviewer going for? Are they trying to replicate the sound of the amp in the room? If so, what room? What cabinet? What speaker? How was it mic'd? Is the room damped? Is the room small or large? How is it shaped? Have they played this amp in a variety of settings, gigs, rooms, power supplies, etc. or just at home at low volumes? Have they ever played it in a mix or just at home in their home studio? Maybe they are they just trying to make the amp "sound its best." If so, what does that mean? According to whom? This all has an impact.
I really enjoyed the video that Zach Wish did where he showed how he records guitars. It was fascinating because you get to see everything I mentioned above play out, and it was very well done an insightful. But one of my takeaways is that Zach does a lot of post-processing on his recordings. For example, he goes through and pulls out certain "off" frequencies from his recordings (watch his video for more info). I am not criticizing him for this; I totally get it. He wants to present the amp in the best light possible. But how many people watch one of Zach's excellent demos and
don't know all of that production and recording skill is being utilized? I bet 99 out of 100. So here are all these people watching a gear demo that have no idea that this isn't the true, unaltered audio from the recording. But they are taking the demo as gospel for how the amp sounds.
Again, I want to be 100% clear: I am not criticizing Zach. I like his videos and playing a lot. His video of the Grace is what inspired me to buy one. I'm just saying it's fascinating how people accept all these reviews as "true" or "real" when in fact a lot of things in the recording and production process have impacted what they're hearing. A lot of work is done behind the scenes that they don't know about. Yet, people take these videos very seriously and they're willing to fight people they don't know over all of this. It's insane.
