Spacexpander

- tube driven spring reverb manufactured in the sixties by the US HiFi-Company "Fisher" (Also well known for their Radio Receivers).
- 2 separate units: spring cabinet and tube pre/post-amplifier
- separate potentiometer for control of reverb amount and bypass function (used as remote control)
- Was used in Hammond organs, home Stereo sets, radio stations and even for car Hifi systems
- current supply: 110V AC only
- mono (one reverb channel)
- high noise level (by today's standards)

This is presumably the reverb unit that was used at KingTubby's studio:
King Tubby's friend and follower King Jammy (then "Prince Jammy") mentioned in an interview that they used a modified fisher reverb: "... The reverb unit that we used to use there, it was a Fisher reverb, an' we change it up to become a King Tubby and Fisher! (laughs). ..."
Since Fisher produced no other reverbs I assume that this IS the unit they used.

So far I tried out 5 different spring reverbs myself and none comes closer to Tubby's reverb sound than this one.
Check these two samples and compare yourself:

1. a low frequency "pop" going through the spring reverb at King Tubby's (sampled from the very start of scientist's album "Scientific Dub" on Clocktower Records)
click here (44khz/16 bit, 155kbyte)

2. A bass drum sample sent through a fisher spacexpander, the high spring is muted with a piece of lace, sampled directly from the spacexpander output, no eq, no compression

If you retube it with NOS tubes...it sounds even "better" and by saying this I don't mean "cleaner"..you'll pick up some fidelity/headroom, but not at the expense of the sound.

I agree with D..this is the best reverb for dub. You can also use it as a "tube warmer" if you turn the reverb down...that works pretty well too.

John: How does one find out which tubes to get? Where do you get yours? This article about New Old Stock (=NOS) tubes indicates that one should be careful.

There's an auction on ebay at the moment of a pristine Spacexpander (starting at $1000). I won't post the link because it won't work after 6 months.
Anyway it has good photos so I'm posting them to show what a 'new' Spacexpander looks like.
