{"product_id":"rev-40086186","title":"1970s Maestro PS-1A Phase Shifter Vintage Effects Pedal w\/ Ronsound Footswitch, Oberheim","description":"Up for sale, a 1970's Maestro PS-1A Phase Shifter in excellent condition and in perfect working order, complete with a modern Ronsound three-button footswitch. Designed by Tom Oberheim (yes, that Oberheim), the Maestro is an extremely lush-sounding all-analog effect. Engineered to approximate the swirl and dimension of a Leslie, the three rocker switches offer variable speeds and ramp up or down when a new setting is engaged, simulating the mechanical nature of a Leslie rotary speaker.\u003cbr\u003e\u003cbr\u003eOriginally designed for use on a mic stand with a threaded attachment on the bottom of the enclosure (for use with keys), this Maestro comes with a modern three-button switch controlling the activation and speed of the effect in a more convenient, guitar-friendly way. While not true bypass, the PS-1A colors the tone in a pleasing way desirable to many players, rolling off treble brilliance and adding a sweet midrange-centric character.\u003cbr\u003e\u003cbr\u003eThis pedal is very clean cosmetically, sporting the less commonly colored green\/white\/orange trio of rocker switches. The silkscreen graphics are in great shape, the large paper label is intact on the back, and there are only a few minor scuffs and marks on the enclosure.","brand":"Maestro","offers":[{"title":"Default Title","offer_id":39613296771258,"sku":"40086186","price":749.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/4437\/4714\/products\/yu6dlucvfo0fzjrlp57m_93c3e42c-46b9-4d68-9ea1-6fd6918eb8e2.jpg?v=1751552489","url":"https:\/\/mmguitarbar.com\/products\/rev-40086186","provider":"Mike \u0026 Mike's Guitar Bar","version":"1.0","type":"link"}
