Fender reveb tank dating
It did one thing and did it very well with a front-to-back rocking movement, and it stayed in the Fender line for 30 years on the dot, until 1984.
It reappeared in reissue form in 2008 as one of the five Fender Classics effects pedals.
It did, however, feature reverb and a vibrato effect, and it remained in the Fender line into 1970, when it was joined by the Variable Echo-Reverb unit, which offered more versatile control in the form of variable echo speed. Another interesting but short-lived device from the same two-year period was the Fender Dimension IV Sound Expander.
Introduced in 1968, it was a small unit containing an oil-filled drum that spun around and created an “underwater sound” best described as a chorus-reverb-vibrato effect.
The 1961 prototype was covered in brown Tolex, with a leather handle, brown knobs (“tone,” “mix” and “dwell”), flat Fender logo and a Tolex-covered front panel rather than grille cloth.
The production model had wheat grille cloth in place of the front panel; a second option was white Tolex with maroon grille cloth and white knobs to match the piggyback amps and the Twin.
The first of these was the Fender Volume Pedal, introduced in 1954.Fender introduced a second echo unit in 1966, the Echo-Reverb.Its controls weren’t as versatile as the EEC unit of 1963, and it stored sound on a rotating metal-coated disc instead of a tape loop.Teagle and Sprung note that the Dimension IV was cool sounding but temperamental, writing “These little boxes are wonderful—if they work.If they don’t, leave them alone.” There were two types; a “Universal” model that instruments could be plugged straight into, and a smaller, less-expensive model that could be connected to the reverb jacks on the back of Fender Reverb amps.
