For Stamp-Amp+ D-Class Guitar Practice Amp
I used it for making my daughter a battery-powered electric guitar with a built-in speaker and amp. I'm powering into a 35W speaker at 4 ohms with 3x 18650 batteries and it has been going a couple days now on one charge. Worked out perfect for my needs. The saturation sounds pretty sick too just with my hand-built humbucker(ish) pickup.
