Smeltinator Underspin Now available in new 3/4 oz and 1 oz sizes. The classic Smeltinator head design you know — now with added punch. Built to mimic slender baitfish, the Smeltinator underspin combines subtle flash and tuned vibration to trigger hesitant, pressured bass. Key components: Premium SPRO ball bearing swivel mated to a compact nickel-plated willow blade for smooth rotation and strong flash. Ultra-sharp, ultra-strong Gamakatsu hook trusted by tournament anglers. Lifelike 3D holographic eyes and sculpted gill plates for a realistic profile. Universal ribbed baitkeeper that secures plastics without tearing them, unlike traditional baitkeepers. The Smeltinator was developed by Canadian angler Bryan Gustafson with crucial input from Bassmaster Elite Series pro Jeff Gustafson and Northland Tackle founder John Peterson. Designed to perfectly imitate slender minnows common across the Northern U.S. and Canada, the jig earned its reputation on the tournament trail. After years of success, Jeff Gustafson’s tournament wins (including the 2023 Bassmaster Classic) helped cement the Smeltinator’s status. In 2023 Bryan licensed manufacturing to Northland Tackle, reuniting the team that created the jig. What sets this underspin apart are the premium parts and attention to detail. The Gamakatsu hook is a staple in competitive bass fishing for its strength and penetration. Combined with the 3D eyes, detailed gill work, and the anti-tear baitkeeper, the Smeltinator presents an irresistible, life-like baitfish profile that bass find hard to ignore. Available sizes & hook options: Weights: 1/8 oz, 1/4 oz, 3/8 oz, 1/2 oz (plus the new 3/4 oz and 1 oz options) Hook sizes: 1/0, 2/0, 3/0, 4/0, 5/0 Match the hook size to your soft plastic: 1/0–2/0 for finesse swimbaits and 3" minnows, 2/0–3/0 for 4" baits (the size Gussy used during his Elite and Classic win on the Tennessee River with 4–5" minnows), and 4/0–5/0 for soft plastics over 5". The Smeltinator underspin is ideal for pressured waters and forward-facing sonar conditions where accurate baitfish imitation matters most.
