It combines a true stereo physical spring reverb, a dual PT2399 tape-style digital delay, an analog multimode filter, and versatile modulation routing into a single hardware processor.\u003c\/p\u003e\n\u003cp\u003eThe Wellspring blends vintage electro-acoustic spatial effects with modern patch routing. At its core is a four-spring mechanical reverb system featuring two 15-inch (38cm) springs per channel. Unlike traditional short-tank spring reverbs that can sound dark or muddy, the long dual-spring configuration delivers a vast, clear, and open stereo acoustic space while retaining classic electro-mechanical spring physics.\u003c\/p\u003e\n\u003cp\u003eAudio signals enter via the rear stereo line inputs or a front-panel 1\/4-inch mono instrument\/line preamp equipped with adjustable drive and saturation. The signal flows into a stereo delay path driven by twin Princeton PT2399 ICs, known for their warm, tape-like degradation at longer delay times. The delay section offers independent time controls for left (Time 1) and right (Time 2) channels, a \"Follow\" mode that turns Time 2 into a timing offset for ping-pong or Karplus-Strong synthesis effects, and switchable stereo feedback paths.\u003c\/p\u003e\n\u003cp\u003eFollowing the delay is an analog multimode filter (Lowpass, Bandpass, Highpass, Notch) with dedicated cutoff and Dry\/Wet controls to shape incoming signals, smooth delay degradation, or tame feedback. A central \"Magic\" parameter acts as a global cross-feedback loop, feeding the output of the spring reverb back into the PT2399 delay input. When paired with the onboard wide-range LFO, which reaches audio frequencies and modulates delay and filter parameters independently, the Wellspring functions as a dynamic space-and-time sound design laboratory.\u003c\/p\u003e","brand":"Teaching Machines","offers":[{"title":"Default Title","offer_id":58773706244428,"sku":null,"price":1499.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/3055\/0604\/files\/teaching_machines_teaching_machines_wellspring_stereo_spring_reverb_machine_240081_1_800x534_556b9954-fc06-4d3a-9f04-2a3c1488ab35.webp?v=1789214838","url":"https:\/\/www.schneiderskeller.co.uk\/products\/teaching-machines-wellspring","provider":"SchneidersKeller","version":"1.0","type":"link"}
