Teenage Engineering EP-35 K.O. Portable Amp
Teenage Engineering, the Stockholm company best known for the OP-1 synthesizer, fitted its EP-35 amp with a storage compartment for cables, accessories or beer. The 35-watt amp plays through a 4-inch woofer and a 1-inch tweeter, with inputs for a guitar, a microphone and a phone over Bluetooth, plus eight guitar effects and eight mic effects. It lasts about 12 hours on a charge at volume 5, has a camp light with an auto mode and a disco mode, and is splash resistant against sweat and spills. Pair a few together over Bluetooth to play in stereo or fill a larger space.
