The system emphasizes modular routing and hands-on control, with individual modules offering dedicated controls and modulation options.<\/p>\n<p>The design uses <strong>vacuum tubes<\/strong> throughout much of the signal path, with supporting circuitry added where needed due to practical considerations like space and heat.<\/p>\n<p><strong>Features:<\/strong><\/p>\n<ul>\n<li>5U modular effects system designed for external audio processing<\/li>\n<li>Tube-based signal path combined with transformers and inductors<\/li>\n<li>Seven-module configuration, including:\n<ul>\n<li>Dual-channel tube microphone preamp (with Lundahl transformers)<\/li>\n<li>Dual phaser with multi-stage phase shifting and LFO<\/li>\n<li>Dual filter bank with inductor-based filtering<\/li>\n<li>Bucket-brigade delay with tube stages in the feedback path<\/li>\n<li>Stereo spring reverb with shielded tanks<\/li>\n<li>Sample &amp; hold and envelope follower module<\/li>\n<li>Output\/phones and power supply modules<\/li>\n<\/ul>\n<\/li>\n<li>Dual-channel (stereo-capable) design across most modules<\/li>\n<li>Integrated modulation sources (LFOs, envelope follower, S&amp;H)<\/li>\n<li>Combination of tube and solid-state components for signal handling<\/li>\n<li>Designed for studio use and modular system integration<\/li>\n<\/ul>\n<p>Here&#8217;s a first look:<\/p>\n<p>https:\/\/www.facebook.com\/reel\/2036331657294442<\/p>\n<p><strong>Pricing &amp; Availability:<\/strong><\/p>\n<p><strong>Knif Audio<\/strong> has not yet <a href=\"https:\/\/www.knifaudio.com\/knifonium-modular-fx\">announced<\/a> pricing or release dates for Knifonium Modular FX.
