This now discontinued all-tube 1x15 tube amp is geared towards players who appreciate the huge, bold sound of the Thunderbolt model, but need a lush, all-tube reverb to fill out their sound. The 1675RT Rhythm Master is rooted in Supro tradition, loaded with independent Bass and Treble controls, a six-spring long-pan reverb, bias-based tube tremolo and switchable power.\n\nThe Rhythm Master’s 35-Watt Class A (Cathode Bias) mode delivers a more spongy, vintage character while the 60-Watt Class AB (Grid Bias) mode delivers faster transient response with maximum available headroom and volume. The tube complement includes a Sovtek 5U4 rectifier, matched Sovtek 6L6 power tube pair, and a pair of JJ preamp tubes.\n\nThe blue rhino hide tolex is extremely clean save for some minor staining on the bottom of the cabinet, topped off with a premium leather handle. The faceplate is nigh flawless with all original knobs, and the silver sparkle grillcloth retains the small raised Supro badge.","brand":"Supro","offers":[{"title":"Default Title","offer_id":42674514034944,"sku":"00185","price":1349.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/4437\/4714\/products\/medium_1e7d7652-f3cb-4837-adb8-ba6561c4aef8.jpg?v=1751524379","url":"https:\/\/mmguitarbar.com\/products\/2015-supro-rhythm-master-1675rt-60-35-watt-1x15-tube-combo-amp-thunderbolt","provider":"Mike \u0026 Mike's Guitar Bar","version":"1.0","type":"link"}
