Interesting disgression !
I've just seen so many corksniffing people worry about the tiniest detail about their guitar, the finish thickness, cable type, IEC cable type, tube brand, potentiometer brand etc. etc., then go on stage looking horrible staring at their feet all night. They would have been way better off paying less attention to all of that and more to their stage presence which is going to be way more noticeable to the people paying them.
I have seen good players playing all levels of gear. Why do people assume that if someone has expensive gear that they can't play as well as they do? I have made a decent amount of money playing my guitar. I use a variety of guitars and other gear, some expensive and some not. Should we all be ridiculed for having an expensive Kemper on the stage?
To me these complaints sound more like jealousy. I have seen people crap all over PRS guitars, until they can afford to get one. Then they brag about them to everyone. I have never subscribed to any of this. We all get to spend our money on whatever we want to. It has nothing to do with your level of skill.
IMO, and following what i've bought/done during all these years with my rigs, my conclusion is : the most important is the chain between Pickups (really important) to speaker, rest is wind.
I've already bought a sommer cable and the incidence on the sound was real.
I broke it and didn't buy another one. I don't record and play in a band at rehearsal and gigs so it's less important.... But if i would be led to record, i would probably improve this part...
It's not a question of opposing good players with cheap device versus bad players with high end ones....
It's just a question of telling honestly what have an incidence on the sound and how.... I join Dynochrome about guitar's detail and some guitarist snobery or cutting hair for nothing....
I've fallen in this trap to think that changing device/guitar should make me a better guitarist....
It's better to buy a good rig from the beginning cause you'll keep it and won't waste money (and time) to change and switch your devices all over the years but it's less and less probant nowdays (poeple love owning and/or changing).
If i had an advice to tell to a beginner it would be ; go and try the guitar in a shop, choose the one on which you feel most confortable, if you dislike the sound ; change pickups.... Done... Enjoy
I think some justify the 1000/2000€ more (or even more ) with sound improvement arguments but in my experience it's not true.... The wood is rarer, the polish/finish is better, you like beautifull object and pay for it ; there's no problem about that...You prefer paying more for american workers instead of asian ones, (the cost is not the same of course).... It's a choice.
I can make an analogy with photography. I've bought a good tripod years ago. This is one rare thing i've kept and cameras have turned over...
