While it would definitely be cool to have a personal roadie swapping out your guitars whenever you need to switch, most of us mere mortals need to find a more mundane solution to storing and accessing our guitars. Finding a multi-guitar rack that works for you boils down to how many guitars you have, how hard you are on them and your rack, and how much space you have to fit them in.
How many guitars will your rack need to hold? Rack options include dual, triple or multiple guitar racks, including some that are expandable. Consider whether the configuration of the rack allows quick access. Consider also whether your guitar’s body shape is compatible (check your flying vees).
If your multi-guitar rack travels with you, it needs to be roadworthy. Solid construction, ease of foldability, durability of moving parts, portability and weight are all factors to consider. Is the foam insulation compatible with both nitro and polymer finishes on your guitar? A warranty is always a good idea.
The amount of available space might dictate the most efficient rack configuration. Small rooms or stages where space is at a premium call for a rack with more storage per square inch than others. The trick is to balance access with storage—a rack is of little use if you can’t reach your guitar!
