The Teensy R4ge Pro mobile platform runs a variety of emulators for a retro-tastic mobile arcade experience. Works as a high-fidelity sound generating and processing platform or synthesizer. Includes a 10dB booster circuit with variable gain control, suitable for applying digital effects to a variety of audio input sources - including electric guitars.

Powered by a LION 3.7V battery or direct from 5V USB, so you can use it on-the-go or plugged in. Features an integrated recharger so you don't have to remove the battery. Use the integrated speakers or use the 3.5mm jack with headphones or powered speakers for more volume.
