<IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... 03/518.jpg" ALT="Spacexpander"> <BR> <BR>- tube driven spring reverb manufactured in the sixties by the US HiFi-Company "Fisher" (Also well known for their Radio Receivers). <BR>- 2 separate units: spring cabinet and tube pre/post-amplifier <BR>- separate potentiometer for control of reverb amount and bypass function (used as remote control) <BR>- Was used in Hammond organs, home Stereo sets, radio stations and even for car Hifi systems <BR>- current supply: 110V AC only <BR>- mono (one reverb channel) <BR>- high noise level (by today's standards) <BR> <BR>This is presumably the reverb unit that was used at KingTubby's studio: <BR>King Tubby's friend and follower King Jammy (then "Prince Jammy") mentioned in an <A HREF="http://niceup.com/writers/steve_barrow/ ... terview</A> that they used a modified fisher reverb: <FONT COLOR="119911">"... 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). ..."</FONT> <BR>Since Fisher produced no other reverbs I assume that this IS the unit they used. <BR> <BR>So far I tried out 5 different spring reverbs myself and none comes closer to Tubby's reverb sound than this one. <BR>Check these two samples and compare yourself: <BR> <BR>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) <BR><A HREF="http://www.interruptor.ch/audio/scienti ... wav">click here (44khz/16 bit, 155kbyte)</A> <BR> <BR>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 <BR><A HREF="http://www.interruptor.ch/audio/spacexp ... wav">click here (44khz/16 bit, 121kbyte)</A>
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. <BR> <BR>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.
