I have just joined a band playing bass. Someone said I should have a few tools around for gigs. Give me a list of tools I should keep in a bag in case something goes wrong on stage.

Here is a list of tools you should have in your gig bag:

- A small multi-screwdriver. This can be handy for tightening loose screws on equipment or making sure the knobs on your gear are secure. There are hobbyist screwdrivers that have multiple tips stored in the body or shaft. In a pinch, you could even use the mini toolset for repairing eyeglasses. These sets are often cheap and low quality, but the screwdrivers tend to be good enough for a quick fix on stage.

- A flashlight. While there may be stage lighting during the performance, if you need to make a quick repair, it is better to have a small but effective light source of your own, in case of emergencies. You can certainly use the big bulky one from home, but a pen light might be more effective and easier to use when you need to hold tools as well. If hands-free is your thing, you could also get a headlamp, which usually has a small strap attached to it. But if you have a modern cell phone, you probably already have an app that turns on the camera flash.

- Pliers. A small pair of pliers can work wonders for a bent jack or for cutting and replacing a broken string. They don’t need to be too big, and you can usually find a small set of two or three at your favorite hardware store. 

- Allen/hex key set. These might not be completely necessary for certain players, but Allen screws are used on a lot of musical equipment, so it would be a good idea to have a set around. While you can buy keys as a set for a toolbox, keep on the lookout for a set that looks like a Swiss Army knife, commonly called a Gui-Tool. These specialty tools often have screwdriver bits built in, making it a very effective multi-tool to have in your arsenal.

Although there are far more tools available, this should get you started and have you prepared for many unforeseen circumstances at your show. Break a leg!
