I have found that the variety of shapes/sharpness of my V-Picks has really been a great tool for tone shaping. I've had them for about 5 months now. I have a: Psycho, Acoustic (I use it on electrics and acoustics), Standard, Rounded, and a Shredder (the small one) just switching from each I can make dramatic changes in the attack of the notes, the thickness of the tone, and even how hard I drive the pups/input of the amp. If I am getting breakup with the acoustic/shredder pick, I can switch to the rounded and actually get about a bit more clean headroom just because the pick has a soft attack. Pretty cool product that has actually become GAS reducing rather than inducing, and much cheaper than doing major changes to the instrument or amp. However....that said, if they are ever produced in colors I might have some GAS to pick out matching picks for each guitar LOL Anyone agree/disagree? Is it really just a placebo, and more a function of me subconsciously choosing different picking styles based on what I think the pick is supposed to do???.......maybe it is, but hey, the ends justify the means, and I like the ends!
