Acus One Forstrings 4 Ferdi
Acus · amplifier
The Acus One for Strings 4 Ferdi is a 40-watt acoustic guitar combo amplifier from the Italian acoustic-amplification specialist Acus, built specifically to reproduce acoustic instrument tone with minimal coloration rather than the electric-guitar-voiced circuits found in most general-purpose combo amps. This entry's brand was previously misattributed to Acoustic, an unrelated American amp maker known mainly for bass amplification; it has been corrected to Acus, the actual Italian manufacturer, since the two names look similar but represent entirely different companies with different product focuses.
