Teenage Engineering Launches the EP-35, a Battery-Powered Multi-Input Amp at $399

Teenage Engineering has launched the EP-35, a battery-powered instrument amplifier with six inputs and built-in effects, priced at $399 and available now. The Verge reported the launch on October 22, 2026.

The amp accepts three types of source: a line-in, a 1/4-inch guitar input, and an XLR input for microphones, including mics that require phantom power (the DC voltage some condenser mics need to operate, supplied down the cable from the amp). Its six inputs feed a summing mix signal path, meaning the separate signals are added together into one output, so several instruments can be played at the same time through one unit. GearNews describes the architecture in those terms.

Beyond the inputs, the EP-35 can stream audio over Bluetooth and receive FM radio, and it can operate as a portable speaker. Multiple units can be linked over Bluetooth using Auracast, the LE Audio broadcast feature (Bluetooth's newer low-energy audio standard), which allows more than one amp to be driven from a shared source. Earlier coverage from MusicRadar characterized the design as a portable, stackable amplifier aimed at outdoor jams, a framing that the stackable and Auracast-linked configurations fit.

The effects section is split into two processors, one for guitar and one for vocals. Each uses style-based presets rather than a conventional parameter set (the individual knobs and sliders found on most effects units), and a single amount knob sets how strongly the chosen style is applied. The guitar presets include "blues," "indie," and "twang." The vocal presets include "radio" and "robo choir." The approach trades granular control for speed: a player selects a character and adjusts intensity, without building a chain of discrete stompboxes.

Hands-free operation is handled through the K.O.-PEDAL, an expressive foot controller with two pressure-sensitive buttons that drive guitar and microphone effects. Teenage Engineering also sells an EP-35 add-on bundle that includes a mic, a USB drive, an amptenna FM receiver, and a K.O. dock kit. A separate EP-35 KO combo pairs the amp with the dock kit and an included audio cable for playing beats through the amp. The company provides an online guide covering the EP-35's features.

For a working musician, the practical questions are power, weight, and how the summing stage behaves under load when several sources are live at once. Those questions are answered only by hands-on testing.

The broader context here is a category shift that has been underway for some time. Amplifiers have been absorbing functions that once required separate boxes, including effects, wireless receivers, and Bluetooth playback. The EP-35 extends that trend with a battery-powered chassis, a mixed-input path, and a radio-and-broadcast stack in one unit. Whether the preset-driven effects approach appeals to players who want deep sound-shaping control is a separate question, and the answer will come from users rather than from the launch announcement.

In my view, the EP-35 is most interesting as an example of how Teenage Engineering packages production tools for people who are not studio engineers. The combination of a pedal controller, a dock for beats, and a broadcast-capable Bluetooth stack points to a player who wants to set up quickly and perform without a rack of equipment. That is a reasonable target, and one the company's earlier instrument and sampler lines have also aimed at. At $399, the amp will be compared with established modeling and multi-input combos, and that comparison will be decided on sound quality and reliability over time.
