Review: Strong case - Perfect unit bag
Review: Wood broke after a year of use. - It’s been about a year since purchase. This case gets consistent use for weekly gigs. Just last week I noticed the top piece of the rack was broken from the front to back of the rack. Still holding shape for now since the wood is covered by the rack material. Not sure if it’s cheap wood or a failed joint. It’s a good rack space but the wood used may not be the most durable in the long term. Otherwise the bag, straps and zippers are all still functional and ok.

## Questions & Answers

**Q: Ok, someone help me out here. Its this rack 8in depth or 12in depth. Title on the item says 12in but description says 8in...Im confused**
A: I called the manufacturer directly and let them know the detail price option container (no info), lead description (12" inch depth) and the detailed description (8" depth) was confusing. They eventually called back and confirmed that this model (RRB30) is 12" in depth. The Rockville website also confirms a 12" depth. If the Rockville team is watching this thread a minor adjustment to Amazon description would help us potential customers :)

**Q: Does this bag come in a 2U size?**
A: I believe the smallest from Rockville is 3U

**Q: what are the internal dimensions?**
A: 7 inches high, 8 inches deep, 19 inches wide

**Q: Does this rack have rear mounting rails? I see conflicting answers to this question. One says 'just front' other says "also rack on both sides".**
A: Mine only has mounting rails on the front. It is; however, an excellent rack. It has been well used yet still looks good. All the zippers and straps have put up with years of use. I use it to carry all my sure wireless gear so I would have no use for mounting racks at the rear. I have the 3 space unit. Hope this helps.

### ⭐⭐⭐⭐ Good quality. Reasonably sturdy. Only downside is rails too close to front of bag.
*by R***T on May 27, 2020*

Good looking bag! Reasonable weight - not super light, but not super heavy. Appears to be about as sturdy as I expected for the price with decent quality nylon. I really like the little zippered compartment on the front to hold extra patch cables and wireless transmitters/body packs. I have no complaints...this is a good value for the money. Very basic so if you need more features, maybe higher priced bags have the things this one could use - - 4 suggested improvements: 1). Set the rails back just a little bit farther from the front of the bag. I am using this for live performance with Shure BLX4R wireless receiver, a Shure PSM 200 In-Ear system, a Behringer MX882 V2 Ultralink Pro mic/line mixer/splitter, and a Furman power conditioner with pull-out lights, and the rails are set so close to the front that I'm going to have to move them back slightly so the knobs on the PSM and the screen on the BLX4r don't get damaged in the event this is bumped from the front during transport or something is stacked on top of it while standing upright. 2). Could use little more padding at the front of the bag with the rails set this close to front. 3). Add three more zippered compartments on the top and sides for cables & accessories. Why not?! A padded compartment for a wireless mic would be a nice touch. 4). Add some rubber strips to the bottom and the back zippered compartment to protect the nylon. Would help for the unit to grip the top of my guitar amp when tilted back slightly on the stand & protect the nylon when the unit is all closed up and setting on the ground at various times during transport. Again, it appears to be a great value for the money, these are just some features this item doesn't have so go for a higher priced bag if you need these features. Edit 05/28/2020 - I ended up unscrewing the rails and setting them back far enough that the antennas and the front knobs on the gear don’t get damaged in transport. Easy to unscrew and acre back in. In an ATA flight case with a cover it’s ok to have the rails sit right up front since the cover will protect them, but in a gig bag they need to be set back a bit so knobs and such don’t get damaged from outside bumps and things that get piled on during transport. This is GREAT for local gigs where the artist transports their own gear, but won’t work well for a touring artist where the bag can get tossed in and out of a bus or a plane. Again a great value for the money for a non-touring artist.
