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!

Nice shoes!
Size: 11, Color: Black Full Grain
I bought them in black and I like them so much I will be buying the brown soon. They fit true to size and are comfortable and stylish. I like the clean simplicity. They're basically a dressy sneaker which is perfect for my job's 'dress code'. Yet they're stylish enough to be worn weekends or a night out. They seemed just a touch stiff out of the box but IMO that's completely normal and fine - after just a couple days of wearing them they are breaking in nicely. No complaints on that. They seem to be of very high quality and I'm very happy with them.
