MOD Reverb Tank 4EB3C1B Universal Stainless Steel - Long Decay

Our review of the MOD Reverb Tank 4EB3C1B finds it best suited for guitarists and techs who need a rugged, no-nonsense replacement that preserves and enhances amp reverb character. It replaces the 4EB3C1B and fits several Fender reissue amps as well as select Music Man, Peavey and Traynor models, making it a practical upgrade. The single biggest reason to buy is the combination of solid construction and a long, thick-sounding decay that delivers a musical reverb without complex modification or tuning.

Key Features

• Direct replacement: Drops into amps that accept the 4EB3C1B or Fender 0050394000 part number without modification, simplifying maintenance.
• Long 2-spring design: The Type Long (2 Spring) tank gives a pronounced, roomy decay suited to vintage and modern amp voicings.
• Durable build: Stainless steel construction provides ruggedness and consistent response in gigging and workshop environments.
• Clear electrical fit: 600 ohm input and 2,250 output impedance match common amplifier circuits for predictable tone and level.
• Horizontal mount: The open side down mounting configuration matches the chassis arrangements used in many Fender and compatible amps.

Who It's For

The MOD Reverb Tank is ideal for owners of Fender Hot Rod Deville, Hot Rod Deluxe, Blues Deluxe and Blues Deville reissue amps who want a straightforward, high-quality replacement that restores or improves reverb character. It also suits players with compatible Music Man, Peavey or Traynor YCV50 amps who prefer a thick, long decay.

It is less appropriate for someone seeking a built-in locking mount, a different reverb decay profile (short or bright), or a tank designed specifically for nonstandard chassis orientations. If an amp requires a different impedance or physical mounting, measure first.
