I think it's a great idea to have sound samples with different guitars, but, depending on price point, it might not be that big of a deal. If you show case some good tones through a couple guitars, that will get most folks interest including mine (the video was almost enough for me). Bottlehead has a strong reputation for cranking out killer gear in my mind, and I can't wait to get my hands on one. I'm almost more excited to see how this community starts tweaking it. Adjustments to the tone stack, swapping in new tubes, trying different capacitors , and getting the amp tweaked specifically for jazz, rock, country or whatever. The brake is a fabulous idea, and really important to me, a home player. Keep the sneak peaks coming, and I'm sure I'll be in line with a bunch of others for that first run. I should be done building my Crack by then.
