Originally I wanted a bag for smaller gigs. Something big enough for a preamp pedal, some in ears, cables, IPad and maybe a place to hold a water bottle.
This bag will easily fit all that, along with my bass head, music stand, guitar stand, and the giant Vic Firth cans I like to wear instead of headphones! It'll probably fit an additional 40t of gravel because this sucker is quite enormous.
Construction wise it is very well made. Nothing feels cheap here, even the water bottle pouch's netting and elastic bands feel very secure. The padding is well thought out and very safe for my gear. The padding on the inside is even "egg crate" so control board knobs (or my amps feet) won't wear through the bag. And when I invariably overload it the strap is padded and recessed so it sits comfortably!
Being able to keep everything you need to play in one spot at all times; its really worth its weight in gold for me.
