If you have a Gig-bag that is made out of material and you worry about it raining when your out and about with it slung over your shoulder. Buy a Can of Running Shoe protector and give your bag a few coats, making sure to allow each coat to dry before applying the next. It won't make it water proof but it will offer you a little more protection at minimal cost

If your pick starts to feel slippery, wash it with a washing up liquid and water solution to remove dirt and oils that your fingers leave behind. Then Then take a fine graded piece of sandpaper and gently sand the pick to roughen it and improve the grip.

If you have a spare Gig-bag lying around taking up space, put it to good use. They make excellent storage bags for pedal boxes and effects boxes, you could even put the gear inside the boxes before stowing them away in your Gig-bag creating even more space.

Use foam pipe insulation to pad out your Guitar stand and inside your gig bag for extra protection.
