If you’re looking for the ultimate small-band amplifier, the ACUS ONEFORSTRINGS 8Ferdi takes everything great about the 5Ferdi and cranks it up to a whole new level.

Why Upgrade to the 8Ferdi?

• Larger Tweeter for Crystal-Clear Highs – 50W tweeter (vs. 20W on the 5Ferdi) ensures even more detail and sparkle in the upper frequencies.
