When Daniel first expressed interest in an effects unit, we talked about many different possibilities: from a wah wah, to a reverb unit, and so on.  However, what he really wanted was something that was very distinctive and prominent, hence we decided on a ring modulator.<\/p>\n\n\n\n<p>Normally seen as unmusical and rather harsh, this unit is anything but.  First off, the signal goes through a simple transformer, then a vintage Germanium bridge rectifier and back through another transformer.  This is the classic method of a passive ring modulator.  The signal is then amplified by a single triode and mixed with the &#8220;dry&#8221; signal.  The dry signal actually is able to be effected as well while a gain, mids and tone control are all available.  <\/p>\n\n\n\n<p>The carrier section includes a multi-waveform (square, triangle or sine) inbuilt oscillator.  A frequency range control on the large dial allows for a frequency from 10Hz to 1MHz in ten switchable steps&#8211; the pot in the middle allows the user to sweep this frequency.  With a multi-turn null pot (here labelled &#8220;Sensitivity&#8221;) and perfectly matched diodes, carrier bleed-through is non-existent.  The black jack input accepts an external carrier signal.<\/p>\n\n\n\n<p>Check out the unit in action by seeing the Andromeda Mega Express Orchestra!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Built for Daniel Glatzel &#8211; Andromeda Mega Express Orchestra The Maconi Musical Modulator is a tube ring modulator effect unit built from an old defective Marconi universal bridge measuring device.
