In order to achieve our concept of ideal sound, our Integrated Series was started as FREE THE TONE’s 15th anniversary project, based on our expertise and extensive experience cultivated and accumulated over the years, and our innate sense of tone. The third release in this series is the “Instrument Cable CUI-6550.” The CUI-6550 cable has been productized as part of our Integrated Series by changing the structural members of our instrument cable CU-6550 and performing a different sound tuning. The CU-6550 succeeded in having a soft and natural tone based on the concept of creating a “sound you don’t want to stop playing.” The new CUI-6550 inherits the basic sound character from the CU-6550 but its tonal balance has been moved to the lower side in order to adapt to the modern music scene and achieve a more punchy sound that won’t be easily masked by other instruments. This is the kind of sound made possible only by FREE THE TONE thanks to our extensive efforts to check and tune our product’s sound at recording studios and concert venues. After investigating the many essential elements for instrument cables ― sound quality, durability, flexibility, weight, etc. ― in detail, we completed the CUI-6550 cable. Try it yourself and experience this sound!
