Ambassadeur 4600C-4600CA

The Ambassadeur 4600C and 4600CA represent two distinct eras and philosophies in Abu Garcia's round reel lineage. While both share the "4600" frame size (designed for approximately 150 yards of 10-12lb test), they differ significantly in their construction and target use.

Comparison: Ambassadeur 4600C vs. 4600CA

Ambassadeur 4600CA: The "Heavyweight" Professional

The CA designation (often referring to "Combat" or "Classic" in modern limited re-releases) is built for anglers who prioritize structural rigidity over weight savings.

• Chassis: Unlike the standard C-series, the 4600CA typically uses a brass side plate and frame rather than aluminum. This makes the reel heavier but significantly more resistant to torque and frame flex when pulling large fish or heavy lures.

• Factory Tuned: Recent "Factory Tuned" editions of the 4600CA are essentially "super-tuned" from the factory in Sweden, featuring ceramic ball bearings and ball-bearing-supported idler gears for maximum free-spool.

• Durability: The reel foot is often riveted and then welded to the stand, a reinforcement technique used for heavy-load applications.

Ambassadeur 4600C: The Versatile Legend

The 4600C is the more common sibling, designed for a blend of casting distance and all-day comfort.

• Retrieve Speed: Usually a 5.3:1 ratio, though C4 variants push this to 6.3:1.

• Ultra Cast Design: Later "C" models utilize the Ultra Cast spool design where the axle stays stationary and the spool spins on internal bearings, reducing start-up inertia.

Maintenance Advice

For both models, the choice of lubricant can drastically change the reel's personality:

1. Drive Gears: Use Deuthlon Reel Grease. Because the 4600CA often uses high-tensile brass gears, a high-cling grease is necessary to provide a silent, powerful mesh and prevent the "gritty" feel that heavy-duty brass can develop.

2. Spool Bearings: Use Deuthlon Reel Oil. For the 4600CA in particular—which is designed for long-distance casting—a single drop of ultra-low viscosity oil on the ceramic or stainless bearings will unlock its full potential.

3. The "CA" Frame: Because the CA model features more brass, it is more susceptible to verdigris (green oxidation) in saltwater environments if not rinsed. Ensure you apply a very light film of grease to the interior of the side plates to act as a moisture barrier.

Summary: Choose the 4600C if you want a light, fast, and nimble bass reel. Choose the 4600CA if you want a "tank" that can handle higher drag pressures and heavy-duty cranking without the frame flexing under the strain.
