Purchased about six months ago for 69,800 yen. I checked the sound and then stored it. I wanted to keep it, but I'm selling it to organize my equipment. The following is a quote from the builder: Product Description This is a unit made with respect for the DS-1. Inspired by the desire to use the DS-1 on my main board, I've customized it to drastically improve only the good aspects while still retaining the DS-1 feel, by using expensive, high-quality parts. I've corrected the strong mid-high frequencies, increased the thick components, and added distortion components that don't get crushed, The roughness of the distortion components was also determined after creating and thoroughly playing dozens of samples. By reducing the cheap sound elements and emphasizing the natural sound elements, I've reconstructed it as a DS-1 that even feels a little organic. As a particularly important point, I tried a fuzz-like approach, and I've created an excellent setting where you can switch between crunch and drive only by operating the guitar's volume knob even when the distortion knob is at MAX (the volume operation may not work well depending on your guitar, but please understand that this is a very sensitive part due to the numbers). The IC uses a Motorola dual metal can MC4558CG. For the part that most affects the sound quality, I've used extremely valuable vintage parts with gold-plated leads, carefully selected from dozens of types. I've also improved the constants, including the capacitor parts, to aim for the best sound output. The two-tone black and fluorescent orange with a blue LED make it easy to identify on the board visually. While still a DS-1, it creates a powerfully thick FAT sound. Please try this best DS-1 MOD, modified to have such a very clear and lustrous, thick sound. ♦︎About SoundQture boutique ♦︎ Sound Couture boutique MOD is a series that modifies the concept of sound dress-up by replacing the low-cost parts often used in mass-produced products to maximize the potential of the masterpieces.
