I understand man - I’m just replying because I’ve been the one who’s had a real life experience with one. Not trying to belittle your experience in any way - glad you’ve played for a long time too, you can understand where I’m coming from - of course I’m not saying that technique can not change frequencies. I am saying that in my case this wasn’t the cause of difference and I’m 100% sure about it. That’s all.
Gotcha. Fair enough.
