The Ultrasound CP-100 is a compact, powerful
2-channel amp that keeps your amplified acoustic guitar sounding
acoustic. It has an 8" LF driver and HF horn powered by 100W. 2 channels
each have combo XLR/1/4" inputs so they can be used for either guitar
or microphone, and the inputs also have phantom power for condenser
mics. Each channel has 2-band EQ, and channel 2 has a notch filter for
eliminating feedback, as well as a shape switch that scoops the mids. A
bank of 16 digital footswitchable effects (reverbs, delays, flanges,
choruses, auto wah, and rotary) can be assigned to either or both
channels. Other features include effects send/return, an unbalanced line
out for connection to a mixer or slave amp, and a balanced DI output
for connection to a recorder or sound reinforcement system.

A fantastic upgrade to my old SWR Strawberry Blonde. Couldn’t be happier! Nice doing business with you, Michael.

Return Window

This product can be returned within 14 days of receipt.

General Terms

Items must be returned in original, as-shipped condition with all original packaging and no signs of use. Buyer assumes responsibility for all return shipping costs unless the item was not received as described.


Buyer receives a full refund in their original payment method less any shipping costs.

Special Conditions

Guitar Returns

All guitars have a 48 hour approval period. If you are not satisfied with your purchase you may return it for a refund. Guitars which have had custom work done (i.e. setups, pickup install, etc) are not eligible for returns. Guitars which are custom ordered are not eligible for returns. Shipping fees and customs duties are not refundable.

Amp and Pickup Returns

All amplifiers, pickups, and pre-amps have a 45 day return policy, calculated from the date of purchase. If you are not satisfied with your purchase you may return it for a refund. You will be responsible for round trip shipping and bank fees and the item must be shipped back before the termination of the 45 day return period. Any after market modifications done by us or anyone else (i.e. voltage switches) will void the return policy. Items marked as "Free Shipping" are still liable for round trip shipping charges if returned. All original packing materials, manuals, and other accessories must be included with the return. Failure to do so can result in our inability to refund the entire amount and/or refusal to accept the return.

Pickups which have been installed are not eligible for returns.
"Dead on Arrival" Policy

Any new amp or pickup which is defective out of the box (i.e. dead on arrival) will be replaced free of charge. If the customer chooses to just return the item for a refund, then it will be treated as a normal return (i.e. the customer pays roundtrip shipping charges.)
