The ONEFORSTRINGS 4FERDI amplifier is compact and very light, but does not sacrifice the necessary power. With a power of 40 watts, it can be powered with an external adapter (included) or via a USB-C Power Bank, allowing it to be used anywhere.

This amplifier features two separate inputs: one for microphone and one for line, plus 2-band EQ, effect and master volume controls. Thanks to its Bluetooth audio input and TRRS audio input/output, the 4FERDI is highly versatile, ideal for live streaming situations and home recording.
