I discovered <a rel=\"noreferrer noopener\" aria-label=\"Marble (opens in a new tab)\" href=\"https:\/\/riversynths.com\/product\/marble\/\" target=\"_blank\">Marble<\/a>, by River Creative Technology a while back, watched the demo video on their site and kept it in mind.  Then I saw a manufacturer&#8217;s kit for it on Synthcube.  This is one of the easiest kit&#8217;s in Eurorack DIY.<\/p>\n\n\n\n<p>What does it do?  It is a stereo tone control with CV.  Marble is based around the concept of spectral tilting. A single knob allows you to tilt the frequency spectrum of an input signal around a fixed point: boosting low frequencies while dampening the high or vice versa. The slope of this tilting curve is special too, it approaches 3db\/octave at maximum.  Each channel can be switched between spectral tilt and mid-range bell equalization.  It also features variable feedback with soft saturation.  You can make it scream or growl if you want to.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>I plan to start using Marble as a final stage before leaving the modular.  But I will also experiment with using it internally to a patch as an effect.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"480\" data-attachment-id=\"3524\" data-permalink=\"https:\/\/pugix.com\/synth\/river-marble\/marble-kit\/\" data-orig-file=\"https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?fit=640%2C480&amp;ssl=1\" data-orig-size=\"640,480\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;1.8&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;iPhone XR&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1582811710&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;4.25&quot;,&quot;iso&quot;:&quot;25&quot;,&quot;shutter_speed&quot;:&quot;0.0083333333333333&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"marble-kit\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?fit=640%2C480&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?resize=640%2C480&#038;ssl=1\" alt=\"\" class=\"wp-image-3524\" srcset=\"https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?w=640&amp;ssl=1 640w, https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?resize=500%2C375&amp;ssl=1 500w, https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?resize=220%2C165&amp;ssl=1 220w, https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?resize=250%2C188&amp;ssl=1 250w, https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?resize=355%2C266&amp;ssl=1 355w, https:\/\/i0.wp.com\/pugix.com\/synth\/wp-content\/uploads\/2020\/02\/marble-kit.jpeg?resize=90%2C68&amp;ssl=1 90w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><figcaption>Marble Manufacturer&#8217;s Kit<\/figcaption><\/figure>\n\n\n\n<p>The kit contents (shown above) consist of the panel, PC board with all SMD parts already soldered, and a bag of panel parts:  jacks, pots, switches, and knobs.
