The ONEFORSTRINGS 10FERDI amplifier is a powerful 350-watt amplifier, designed for acoustic and classical guitars. It is equipped with 3 separate inputs, plus an Aux input (TRRS audio in/out and/or Bluetooth audio), each with independent volume control and a 2-band equalizer.

The 3 inputs include gain control, 3-band EQ, FX send, and volume. Input 1 offers additional features such as a compressor and a switch that adjusts the channel characteristics depending on the selected instrument type:

1. Flat: "Standard" equalization for acoustic and classical instruments, making channel 1 identical to channels 2 and 3.
2. Bass: Ideal for instruments with a pronounced bass range, such as electric bass, acoustic bass, or double bass.
3. Jazz: Designed for electric or semi-acoustic/jazz guitars.
