Summer School Electronics Extra Credit BoostThe Extra Credit is two boost pedals in one. With the toggle switch to the left, the Extra Credit is a one knob op amp boost. With the toggle to the right, the Extra Credit becomes a transistor based boost. This engages the Brightness control for extra top end sparkle and grit to be added to the signal. The Extra Credit works great at the end of your chain for solos, in front of your favorite overdrive for added grit, or as an always on preamp!

Mineral sunscreens have yet to master blending in and this is no different. If you're thinking of hitting the beach with your sexy bum protected it'd better be a ghost beach because you'll look like you've been dipped in white paint. Oh, and it doesn't wash off, so be prepared to look like Casper for days to come. It rolls on fine if you shake it well first and it does protect.

Go-To for Reef-Safe & Light-Weight Sunscreen

Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)

Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.

Great choice

Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)

After I suffered a second-degree burn from steam, I was told by my doctor that I would have to keep my new fresh skin sun-blocked for up to a year to avoid any scarring or hyper pigmentation. This has been a great selection as it is a roll-on, Which helps a lot with preventing messes that can happen with traditional sunblock bottles. I also like that it is easy to travel with, and the fact that it is zinc based.
