Teenage Engineering is not selling you one box anymore. It's selling you a rig.
On October 22, 2026 the Swedish company dropped the Teenage Engineering EP-35 K.O. AMP and EP-127 K.O. Pedal, and surrounded both with a deliberate pile of accessories: mics, radios, cables, bags, a dock. Taken on its own, a 399 euro portable amp is a niche purchase. Taken as a system built to plug into the EP-133 K.O. II and EP-136 K.O. samplers that TE has been shipping since last year, it reads as a company trying to own an entire portable-production category, not just sell a gadget.
What's actually in the EP-35 K.O. AMP?
Six input channels sum into one mix: a quarter-inch guitar input with switchable low and high gain, an XLR mic input with 48V phantom power, stereo 3.5mm line in and out, and two USB-C ports that double as a USB audio interface. Bluetooth handles wireless playback, including LE audio and broadcast mode. On top sits a dial for eight built-in effect and amp presets, and the amp pushes sound through a 30-watt woofer and 25-watt tweeter across a 50Hz to 20kHz range.
The form factor is the pitch as much as the spec sheet: a lithium-ion battery charged over USB-C, a splash-proof shell for busking in the rain, a built-in handle, and a storage compartment that hides a camping light. It is designed to leave the studio.
Why does the EP-127 Pedal matter for live looping?
The EP-127 K.O. Pedal is the accessory doing the most interesting work. It's a wireless foot controller, Bluetooth-paired to the amp, with two large pressure-sensitive buttons that rock forward and backward for expression rather than just clicking on and off. Hooked to the EP-35, it drives the built-in looper and metronome hands-free, which matters for anyone who has ever tried to loop a guitar part while also fretting it. Plugged into a laptop instead, it switches roles entirely and works as a MIDI or HID controller. It runs on two AAA batteries or USB-C, so it survives outside a power outlet just like the amp does.
What else shipped, and why does the accessory pile matter?
Alongside the two main units, Teenage Engineering released a Handy Mic, an AMPTENNA FM radio receiver, and a USB drive, each at 29 euros, plus a 3-metre guitar textile cable at the same price. A Pocket Bag and an Amp 35 Strap round out the carry options, and a 15 euro K.O. Dock Kit lets the amp physically mount to other EP-series units.
None of those are essential on their own. Together, they're the point: Teenage Engineering is building a modular, low-cost accessory economy around the K.O. line the way console makers build one around a console, locking in a growing user base that buys into the ecosystem one 29 euro add-on at a time rather than one expensive flagship.
The EP-35 and EP-127 don't need to be the best amp or the best pedal on the market. They need to be the ones that already talk to the sampler you own.
Why it matters
For bedroom producers and street performers, this is the first time Teenage Engineering has shipped a full signal chain (sampler, amp, pedal, mic) designed to work together out of the box at prices well under a traditional pedalboard-and-combo setup.
