What happened

Key facts

  • Teenage Engineering launched the EP-35 instrument amp.
  • The EP-35 is an instrument amplifier with built-in effects.
  • The EP-35 features built-in effects.

The brief

Teenage Engineering introduced the EP-35 K.O. AMP, a battery-powered instrument amplifier with built-in effects. The unit is designed to serve synths, guitars and voice, and The Verge reported a price of $399. The EP-35 combines an amplifier with a Bluetooth speaker. SYNTH ANATOMY describes six input channels for guitars, microphone, stereo line signals and Bluetooth audio.

The Verge identifies a line-in port, a quarter-inch guitar input and an XLR microphone input, and says the unit can also receive streamed audio over Bluetooth. The guitar and microphone connections add different capabilities. SYNTH ANATOMY says the guitar input is 6.35 mm and offers low- and high-gain settings.

It also reports that the XLR input provides 48V phantom power for condenser microphones. The Verge confirms the guitar and XLR inputs and notes that the microphone connection supports microphones requiring phantom power. The amp’s battery-powered design is central to its use as a portable speaker for instruments and voice.

SYNTH ANATOMY says the battery recharges through USB-C and that the unit has a built-in carrying handle. Those details complement the input options, making the EP-35 a self-contained setup for several audio sources, according to the product descriptions. The Verge reports that users can link multiple EP-35 units wirelessly through Auracast.

It also highlights the AMPTENNA, an accessory that turns the unit into an FM radio. SYNTH ANATOMY lists the AMPTENNA among several products Teenage Engineering introduced alongside the amplifier. The EP-35 was part of a broader set of new products in Teenage Engineering’s K.O. lineup.

Both SYNTH ANATOMY and The Verge mention the EP-127 pedal; SYNTH ANATOMY additionally names the Handy Mic and USB Drive. Gearnews’ headline also reports the EP-35 K.O. AMP and accessories, but supplies no further product details.

The accounts emphasize different aspects of the product: SYNTH ANATOMY details the channel count, gain settings, phantom power, battery and handle, while The Verge stresses the built-in effects, Bluetooth linking and $399 price. Together, those reported features describe an instrument amp that also functions as a portable speaker and supports multiple input sources.

Why it matters

  • The EP-35 gives musicians a portable way to amplify synths, guitars, or vocals without relying on a separate amp and effects unit, which may be useful for practice, small performances, and mobile setups. Its multiple input types let performers connect different instruments and a microphone to the same battery-powered speaker, though the supplied details do not establish its effects range, sound quality, or price.

What to watch next

  • Over the next few weeks, Teenage Engineering may post EP-35 pricing, shipping dates, and regional availability on its product channels.
  • Watch authorized music retailers for live listings and stock updates, which will show when buyers can actually order the amp.
  • In the coming weeks, audio reviewers and musicians may test the battery life, speaker output, and built-in effects with synths, guitars, and microphones.
  • Teenage Engineering’s support pages may clarify input behavior, power requirements, and any setup guidance as the first units reach users.

How outlets' accounts compare

1 framing difference · 2 uncorroborated claims
The reports repeat the same account with different emphasis; its central claims are not independently confirmed in the reporting Updat3 read.Compared across 2 reports whose article text Updat3 read; 1 other outlet was checked by headline only.
Framing / emphasis differences
Sources emphasise different angles, actors or consequences of the same reporting.
  • The Verge foregrounds built-in effects, Bluetooth linking and the $399 price; SYNTH ANATOMY emphasizes the six input channels, gain settings, phantom power and portability.
Updat3: These are differences of emphasis, not disputes about what is reported. They do not show that the reported claims are true.
One-sided or uncorroborated claims
Claims that come from one party or one source family and are not independently corroborated.
  • The Verge says multiple EP-35 units can connect over Bluetooth using Auracast.
  • SYNTH ANATOMY says the XLR microphone input provides 48V phantom power for condenser microphones.
Updat3: Not independently corroborated yet — treat as a claim, not an established fact.

How we got here

Teenage Engineering’s portable-instrument approach predates the EP-35 by more than a decade. The Stockholm company, founded in 2005 by Jesper Kouthoofd, David Eriksson, Jens Rudberg and Daniel Stenberg, introduced the OP-1 synthesizer in 2011.

The OP-1 brought sound generation, sampling, sequencing and tape-style recording into one portable instrument, with a built-in speaker and microphone. Its significance as background to the EP-35 is not that it was an amplifier, but that it treated a music-making device as a self-contained system rather than a component that required a larger studio setup.
