C.<p>But we can simplify this.</p><p>I'm not putting finished effects into standalone metal <a href="https://mindly.social/tags/boxes" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>boxes</span></a> at this point; I'm <a href="https://mindly.social/tags/experimenting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>experimenting</span></a>, not producing a product. So I have a simple <a href="https://mindly.social/tags/modular" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>modular</span></a> system I cooked up to connect arbitrary effects <a href="https://mindly.social/tags/experiments" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>experiments</span></a> together. One of the things it does is handle the power-supply stuff, so each effect board doesn't need to do any of that. It just receives a nice 0V and buffered <a href="https://mindly.social/tags/Vcc" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Vcc</span></a> (9V) it can rely on, along with a buffered 4.5V to use as a <a href="https://mindly.social/tags/bias" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bias</span></a> voltage when AC coupling <a href="https://mindly.social/tags/signals" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>signals</span></a>, since this is a single-supply system.</p><p>So we can chop out all the power stuff from the schematic, which fills basically a ninth of the image - divide it into 3 rows and 3 columns, like the Brady Bunch intro, and the left-middle square is basically the power section.</p><p>But there's a bigger chunk we can strip out. Boss (and many other) pedals of the era frequently used "soft switching" to enable / disable the effect while playing. If you go back in time, real physical <a href="https://mindly.social/tags/switches" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>switches</span></a> were used, so the signal was actually totally disconnected from the effects circuitry when in the "off" position. This is called "true <a href="https://mindly.social/tags/bypass" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bypass</span></a>", as opposed to the soft switching.</p><p><a href="https://mindly.social/tags/Soft" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Soft</span></a> <a href="https://mindly.social/tags/switching" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>switching</span></a> involves having two signal paths through the effect. One applies the characteristic effect, and the other basically just buffers the signal and bypasses the rest of the effect stuff. This is implemented with transistors and latches.</p><p>2/x</p>
