104-Z Analog Delay Spillover Mod Directions
Introduction
This mod should only be attempted by experienced technicians with a basic understanding of
electronics. You can easily damage your 104 while cutting traces, soldering components, drilling holes
and re-wiring circuits. Please read over all the instructions first and do not attempt this modification
unless you feel confident doing so! Moog Music is not responsible for any damages that may occur to
your instrument while attempting this mod. Contact Moog Tech Support for assistance
(techsupport@moogmusic.com).
The "Spillover Mod" for the 104 will allow you to toggle between normal operation and "Spillover"
operation with a single DPDT switch. The mod switch can be installed on the front panel next to the
Int/Ext Loop (see above pictures). In Spillover mode, you can exit Active mode (green light)
WITHOUT an abrupt end to the delayed signal. Whatever delayed signal is left within the analog
delay chips will die off naturally when you click into bypass mode (red light). For some compositions,
this can provide smoother transition between sections.
Notes:
1. In Spillover mode, the Mix knob is always active (in both active and bypass).
2. The main expense in this mod is the labor (disassembly, hand-wiring a circuit and switch, drilling a
hole in chassis, re-assembly).
