The Isolator circuit has been used for years to create the classic effect of dropping out a specific frequency range, although it can also be utilized as a very effective general EQ as well. This particular circuit is a hybrid affair, the state variable filter is solid state and it is married to a tube output stage stage. This offers a number of benefits: truly wide ranged filters are possible while at the same time offering the compression and harmonics of a tube stage. This means overloading no longer generates nasty distortion artefacts but a wonderfully smooth response. <\/p>\n\n\n\n<p>Even better, as the equalizer is so flexible, it is great on virtually any source and is recommended in the studio just as much as at a live gig. This particular unit is fully transformer balanced on the input and output and has a bypass switch that removes the filter from the signal path but keeps the tube circuit and master volume connected for even more variation of tone. <\/p>\n\n\n\n<p>The original case was rough and ready with plenty of scratches but that adds to the appeal sometimes especially when the front panel can be produced in a matching red color. Further variations of this idea could be reduced in size even more with subminiature tubes and unbalanced connections for portability. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here is one, finally, for all the DJs of the world.
