Used to see a lot of Lear Jet 8 track stuff.  Not sure they offered a reverb though.  These things all work in conjunction but you'll need to have the reverb as the last unit downstream.
8 tracks?  I got a ton of em.  Some are still good.  Just plugged in Cricklewood Green by Alvin Lee/Ten Years After' a couple of weeks ago while I was in the garage.  Then I started smelling something like sweet grass burning so I popped it out and headed for the house!  
 
  
Steve,
Thanks a bunch for the offer but I'm reasonably sure I still have mine somewhere.  Hang on to them, or make Rob/Marlin an 'Offer they can't refuse'.
