Darkglass Harmonic Booster 2.0 Clean PreampThe Harmonic Booster, Darkglass Electronics' first circuit, was meant as a gain stage for distortion pedals but evolved into a powerful clean pre amp. It allows bass players to boost volume and shape their sound without adding distortion. Each volume and EQ control provides a 20dB clean boost or cut, along with a parametric mid control. The unique Character control flatlines the signal when off but adds low end beef and high end sparkle when turned

Doesn't bite
Format: Board book
Got this book to try to teach our two year olds that biting isn't the solution to their problems. They enjoyed it and hopefully some of the suggestions stuck.

Biting tool for toddlers
Format: Board book
My daughter has been struggling with times of biting. We read his book to her after each incident and she seems to enjoy it. I also work with young kids so using this in the special education setting has been helpful as well! Definitely recommend the book. It has helpful info on the back for caregivers as well.

Great Counting Book!
Format: Hardcover
This is a really neat counting book. It's all just beautiful pictures. There's so many things to look at and count and it also helps will telling the time at the hour level on an analog clock.
I thought it would be hard to hold my kindergartner's interest with it, as he gets tired of all the number and alphabet books. He loved this one. I think not having words let him feel in control of explaining what each two-page spread was about, each a different number.
