Teenage Engineering EP-35 K.O. AMP Portable Instrument Amp Bundle with EP-127 K.O. Pedal

The Teenage Engineering EP-35 K.O. AMP Portable Instrument Amp Bundle with EP-127 K.O. Pedal gives you a complete, ultra-portable performance rig for guitar, vocals, synths and more. At the heart of the bundle is K.O. AMP, a 35-watt, battery-powered amplifier with six simultaneous inputs, USB audio, Bluetooth and built-in effects. Paired with the wireless K.O.-pedal controller, you can loop, trigger effects, control playback and keep your hands free to play.

Designed for creative musicians on the move, this bundle lets you plug in guitars, microphones, synths, phones and laptops all at once, then shape your sound with dedicated FX for guitar and vocals. Use the K.O. pedal to punch in loops, ride effects or control your DAW and live set over Bluetooth LE MIDI, USB-C or 3.5 mm MIDI. Whether you are jamming at home, rehearsing with friends or performing in unconventional spaces, this compact system keeps everything tidy, flexible and fun.

Portable 35-watt hub for all your instruments

K.O. AMP is a 35-watt, battery-powered amplifier that acts as the central hub for your entire setup. With six inputs that can all be used at the same time, you can connect guitar, microphone, stereo line sources and Bluetooth audio without menu-diving or input selection. Just plug in and play, making it ideal for spontaneous jams, writing sessions and compact live rigs.

Built-in FX and dedicated controls for guitar and vocals

With eight built-in FX presets for guitar and microphone, plus dedicated FX and FX amount dials, K.O. AMP lets you quickly dial in tones for different players and sounds. Separate gain controls for mic, guitar and line inputs, along with a tone knob for the speaker, give you straightforward control over your mix so you can focus on performance rather than programming.

Wireless hands-free control with K.O. pedal

The EP-127 K.O. pedal adds expressive, hands-free control to the system. Two pressure-sensitive buttons let you trigger and manipulate FX, looping, metronome and playback modes on the EP-35 platform, while Bluetooth LE and USB-C connectivity make it easy to integrate with compatible hardware and software. With 3.5 mm MIDI out and an expression pedal input, it also slots neatly into existing synth or pedalboard setups.

Ready for the outdoors and late-night sessions

K.O. AMP is splash-proof and battery-powered, so it is comfortable at garden jams, campsites and outdoor rehearsals. The integrated handle makes it easy to carry, while the storage compartment with built-in camp light helps you keep accessories, cables or small items close to hand and visible in low light. Bluetooth LE audio with broadcast mode means you can stream music or backing tracks wirelessly, and the USB audio interface lets you capture ideas straight to your computer or phone.

• Six-input portable performance hub - K.O.-amp features six inputs that can all be used simultaneously, including guitar, microphone, stereo line-in, Bluetooth audio and USB audio. Everything is summed internally, so there is no need to select an active input, making it easy for multiple players to join in and for you to blend different sound sources on the fly.
• Dedicated guitar and mic processing - A 1/4" guitar input with low and high gain modes, XLR mic input with 48 V phantom power and eight built-in FX presets for both guitar and microphone give you a flexible front end for instruments and vocals. Individual gain and FX amount controls help you quickly adapt to different mics, guitars and playing styles without extra pedals.
• Wireless K.O. pedal control - The EP-127 K.O. pedal provides two pressure-sensitive buttons and multiple control modes for FX, looping, metronome and playback. With Bluetooth LE and USB-C connectivity, plus 3.5 mm MIDI out and an expression pedal input, it doubles as a versatile MIDI and HID controller for synths, pedalboards and software, giving you expressive, hands-free control over your setup.
• Battery-powered, splash-proof and storage-friendly - A built-in rechargeable lithium-ion battery keeps K.O. AMP running without mains power, while splash-proof construction makes it suitable for outdoor use. The integrated handle, storage compartment and camp light keep your rig compact, easy to carry and practical in low-light environments, from late-night rehearsals to campsite sessions.
