The Splitter-Blend has received long-overdue revisions and refinements. The Return section now uses an dual op-amp rather than simple FET buffers.
Also, thanks to RG Keen's Polarity Reverser article and Gez Paton's sage advice, a phase polarity switch has been included for matching (or intentionally mis-matching) the phase of the effect loops.
Six new sound clips, a perfboard layout, and a PCB layout by Will Percival have also been added to the site.
