Now that I'm becoming proficient on a few different stringed instruments, most notably the banjo and lap-slide guitar in addition to guitar, I've been looking for a way to deal with with increase amount of gear that comes with these. In particular, my desk had become a mess of capos, finger- and flat-picks, and slides. In addition to desktop organization, being able to have everything in one place and ready to grab to take to a jam is important. I looked into little boxes and containers, but nothing seemed to work for this assortment of bits (i.e., some long, heavy, skinny things like slides and dobro capos; metal finger-picks that shouldn't get squished; my favorite picks that are easy to lose).
It dawned on me that a tool rool, like I've seen bicylists use (and seem popular with motorcyclists) might work. I ended up googling "waxed canvas tool rool" and ran across the Coffin Tool Roll by Red Clouds Collective. At $65 it's not cheap, but it's handmade by hipsters in Oregon and is a quality product that should last a lifetime. Along with multiple slots/pockets, it has a zippered pouch that seemed perfect for securing those little pieces (like picks) that are easy to lose. I found a 10% off coupon code which basically offset the shipping, and a few days later it arrived.
Rather than calling it a "guitarist's tool roll," which makes me think of the things like truss rod wrenches and small screwdrivers to tighten tuners etc., I think of it as a "guitarist's toy roll" since it's for all the little gadgets and gizmos that are commonly used in playing acoustic music.
