The CabClone provides the perfect blend of transparency and detail to deliver amazing, accurate and toneful results for your favorite cleans sounds. The Open Back Cab Sim setting provides the most sparkle and shimmer of higher frequencies while low frequencies are well-balanced and intact while the midrange response is slightly more forward compared to the small scoop in mids found in the Closed Back Mode. For clean sounds and beyond, the CabClone provides a tremendous range of tone and options to record your favorite amps and your favorite sounds, direct, along with your mic techniques, on the gig and at home for silent playing via headphones.
