New Gear Review - Ultrasound Amp's CP100 Acoustic Guitar Amp

UltrasoundCP100 Ultrasound Amplifiers’ CP100 Acoustic Guitar Amp

Ultrasound’s CP100 two-channel amp will accommodate a vocal microphone or instrument with its Combi XLR/1/4-inch input while the second channel is especially designed to amplify acoustic guitar, fiddles, mandolins or any other acoustic instrument. I like this amp’s demure, low profile look that may not immediately attract attention until you play through it.

Both channels have phantom powering facilities and both have their own volume, bass and treble controls. The amp uses a single, custom made, 8-inch woofer with coaxial tweeter and 100-watts RMS power. Channel two is specifically designed for closed-miked acoustic instruments with the Shape on/off control for contouring the mid-range and a frequency adjustable (100 to 350Hz) 18dB notch filter for feedback suppression on stage.

The Master section has a Master volume control of your onboard mix of the two channels and a digital effects system with 16 different effects that range from various chorus’, flanger, rotary speakers, delays, room/halls and combinations. There is a wet/dry control and an effects bypass footswitch jack on the back. Effects can be used on either channel separately or both at the same time using a three-way toggle switch.

I found the CP100 super clean, quiet and the build quality good and rugged. Other features of this 30-pound amp are: a peak power limiter to prevent distortion, effects loop jacks, XLR balanced direct recording out, 1/4-inch unbalanced output for feeding PA or driving a slave amp, and L/R Tape/CD RCA input jacks with level trim for playing drum machines or pre-recorded backing tracks through the amp.

Seems like a lot of value to me. The Ultrasound Amplifiers’ CP100 Acoustic Guitar Amp sells for $799.95 MSRP, and for more information, go to http://ultrasoundamps.com.
