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!

Who doesn't like Eric Carle books?
Format: Board book
Always been a fan of Eric Carle books. My 10 month old likes the sounds and pictures. He has other similar books, but we like him to see a variety of illustrations. With the pandemic going on, my he is missing out on a lot. One day we will go to the zoo and see real animals, but for now these books will have to do.

A Gold Standard
Format: Hardcover
This was a purchase for my one year-old grandson. He became very engaged once we started using the book. He loves the sounds and looking at the pictures. The pictures are paper, so be careful sometimes they will rip easily if they turn the page . Also, until he gets a little older, I need to press the buttons for him as some of them are a little harder than others to push. Great way to start teaching words and having fun while doing it.
