Teenage Engineering has released the EP-35, a portable multi-input amplifier designed to handle guitar, bass, microphones, synths and Bluetooth playback from the same box. The $399 unit is available now from the company’s store and supplies 35 watts through a four-inch woofer and one-inch tweeter. Its rear connections include a 6.35mm instrument input, an XLR microphone input with switchable 48-volt phantom power, a 3.5mm stereo line input and USB audio.
The instrument and microphone paths each receive eight dedicated effects. Guitar presets range from clean, twang and blues to overdrive, indie, envelope, acoustic and bass, while the microphone side offers treatments such as radio, pop, rock and “robo choir.” Each preset is controlled with a single amount dial, keeping the interface closer to a compact performance amp than a conventional pedalboard. The official guide also confirms a tone control, headphone/line output and a high-input mode for active pickups or pedals.
USB turns the EP-35 into an audio interface that can send separate stereo channels for the guitar, microphone and line inputs to a computer. Bluetooth 5.3 and Auracast let several units operate together; with a stereo pair, tilting each cabinet left or right before startup assigns its channel. The internal lithium-ion battery is rated for up to 12 hours at the company’s volume-five test setting, with a two-hour charge time using a suitable 45-watt USB-PD supply.
The optional EP-127 K.O. Pedal adds wireless effects control, a simple looper, metronome and expression-pedal input. Together, those functions make the EP-35 unusually broad for a small battery amp: it can cover practice and busking, but also direct multichannel recording and linked portable playback without a separate mixer.
Why it matters
The EP-35 compresses several normally separate tools—practice amp, vocal monitor, audio interface, Bluetooth speaker and looper controller—into one portable system.
