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!

Trendy shirt and great price
Great shirt and great quality! My son loves it and gets lots of compliments. It’s a soft, nice material and true to size. I’ll be ordering from this seller again.

Nice shirt. Size longer than usual
It's a good shirt, nice quality, a little too long as far as I'm concerned, but the quality is good and it's lightweight. Which is what I like. Like. I don't like heavy shirts that need to be washed and washed to be broken in like this one feels now
