ACUS ONEFORSTRINGS 5Ferdi – More Power, More Control, More Versatility

If you loved the ONEFORSTRINGS 4Ferdi, but need more power, more inputs, and even greater tonal flexibility, the ACUS ONEFORSTRINGS 5Ferdi is your perfect upgrade. Designed for small bands, duos, or solo musicians who need serious sound shaping, this 70-watt powerhouse delivers everything you love about the 4Ferdi—but with added control, expanded connectivity, and a wider frequency response for an even richer, more dynamic tone.

With 3 independent input channels plus an Aux input, you get extra versatility for multiple instruments or vocals. Each input has its own Gain, 3-band EQ, effect send, and volume controls, allowing precise sound sculpting for every instrument in your setup.
