In this video, reviewer Justin Horenstein demonstrates the Ultrasound CP-100 Acoustic Amplifier.
This is an amp specifically built for acoustic instruments such as guitar, mandolin, fiddle and even vocals. It has a single 8’’ speaker and 100 watts of power. It’s made to be transparent, so it won’t add color to the tone of your acoustic instrument.
The CP-100 boasts two channels, each with 1/4’’ and XLR inputs. While both channels have their own volume, bass, and treble controls, channel two has a notch filter and shape control to dial in a more specific sound.
Other features include digital effects assignable to either or both channels, line out, direct out, CD/tape input, and an FX loop to allow for more complex signal chains.
Here Horenstein runs through the features and plays through several of the internal effects.
