The Echo Fix Reverb Tank is a replacement spring reverb tank sold by Echo Fix, the Australian maker of tape echo machines. It is the original tank fitted to the company's EF-X2, EF-X3 and EF-X3R units, sold as a spare part for players whose machine's spring reverb needs replacing1.
What it does
A spring reverb tank is the physical spring assembly that gives a tape echo machine its built-in reverb: the audio drives a spring, and the way the spring vibrates adds the boing and decay players associate with real spring reverb. If the tank in an EF-X2 Tape Echo, EF-X3 or EF-X3R is damaged, this is the direct replacement part from the maker1.
Echo Fix sells it as "1 x Original Reverb Tank for Echo Fix EF-X2, EF-X3 & EF-X3R"1, so it is intended for those machines specifically rather than as a generic tank for other gear.
Ordering and shipping
The tank ships from Australia, and Echo Fix states that import duties and fees are the responsibility of the buyer. US players should account for that when ordering.
- Shipping is by Express DHL with a tracking number, quoted at 3 to 5 business day delivery1
- The item ships from Australia1
- Import duties and fees are the responsibility of the buyer1
For players after a standalone spring reverb rather than a spare part, Echo Fix also makes the EF-P2.
