Teenage Engineering EP-35 Brings a $399 Multi-Instrument Amp

Teenage Engineering has entered instrument amps with the battery-powered EP-35, adding guitar, XLR mic, line-in and Bluetooth inputs plus preset effects. For creators, it suggests a simplified portable live audio workflow.

What happened

Teenage Engineering has expanded from its familiar design-focused music hardware into instrument amplification with the EP-35, a previously leaked product now officially available. The company describes it as a multi-input, multi-instrument, battery-powered amp with built-in effects. It accepts a line-in signal, a 1/4-inch guitar input, and an XLR microphone input that supports phantom power, which covers condenser mics used in many recording and streaming setups.

Bluetooth audio streaming is built in, and multiple EP-35 units can be linked over Bluetooth using Auracast. When two units are paired in stereo, tilting a unit to the left or right sets it to the appropriate stereo channel. Teenage Engineering is also selling accessories, including the “amptenna,” which turns the unit into an FM radio, and the EP–127 KO Pedal, a wireless MIDI controller for added control.

Key facts

• The EP-35 amp is available now for $399.
• Rear connections include a line-in port, a 1/4-inch guitar input, and an XLR mic input with phantom power support.
• Guitar and vocal channels use separate effects processors controlled by style-based presets such as “blues,” “indie,” and “twang,” plus vocal presets like “radio” and “robo choir.”
• Multiple EP-35s can connect via Bluetooth Auracast; in stereo, tilting a unit left or right assigns the correct channel.
• Accessories include the “amptenna” FM radio add-on and the EP–127 KO Pedal, which adds a looper, metronome, expression pedal jack, and 3.5mm MIDI output while also working as an HID controller.

Our analysis

For creators and operators who manage live content, the EP-35 likely points to a different type of portable audio workflow. The combination of XLR with phantom power, a 1/4-inch guitar input, and Bluetooth streaming in a battery-powered box suggests the company is targeting small-stage performers, video creators, and podcast-style setups that need a vocal chain and instrument input without a full mixer or audio interface. The single-knob “amount” control over preset effects reduces decision-making during a live take, which may appeal to creators more concerned with consistent output than deep sound design.

The EP–127 KO Pedal is the more meaningful addition for operator workflows. Because it works as a wireless MIDI controller and HID controller, it can control the EP-35’s built-in effects, trigger a simple looper and metronome, and also control software or video playback from a computer. That suggests the EP-35 is being positioned not just as an amp, but as a compact control surface for content production. However, the limited control over individual effect parameters means advanced musicians may find the preset approach restrictive; the tradeoff is speed and simplicity.

What it means for operators

• Evaluate the EP-35 for off-site creator shoots, live demos, or community events where battery power and multi-input connections reduce the amount of gear needed.
• Use the style-based vocal and guitar presets to maintain a consistent audio identity for recurring content without requiring an audio engineer on every take.
• Pair the EP–127 KO Pedal with video playback or DAW software to control cues and looping during live streams, product demos, or short-form recording sessions.
• Test the Bluetooth Auracast stereo pairing for small pop-up or in-person creator activations, but keep a wired backup for critical audio because wireless reliability can vary by environment.
