Add a 1K resistor in series with one of these<\/strong><\/p>\n\n\n\n<p>De-solder one side of D3 or D4 and put a 1K resistor (or less, if you want less of the effect) in series between the de-soldered end of the diode, and the point on the circuit board it had gone to. &nbsp;This will make the clipping asymmetric and soften the edges of the waveform on one side of the cycle for a sound I&#8217;d describe as smoother, more dynamic, and&#8230; not really like adding a clean blend, but moving just 7% in that direction, if that makes sense.<\/p>\n\n\n\n<p>I&#8217;ve tried a lot of diodes here, but this is still my favorite mod. &nbsp;If you experiment, I recommend starting with germanium and Schottky diodes rather than LEDs or other diodes with higher forward voltages than the stock silicon diodes. &nbsp;(LEDs will barely clip at this position in the circuit, leaving you with mostly opamp clipping, almost like lifting the diodes entirely.)<\/p>\n\n\n\n<p><strong>D3 or D4 &#8211; Add a&nbsp;.01uF capacitor in parallel<\/strong><\/p>\n\n\n\n<p>Solder the capacitor to D3 or D4&#8217;s leads, one capacitor leg to each side of the diode. &nbsp;This will filter out some harsh high frequencies; if you want to customize it, larger capacitors will have a lower cutoff frequency (i.e. filter out more treble) and smaller capacitors, vice versa.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Final gain stage<\/h5>\n\n\n\n<p><strong>R26 &#8211; 68K<\/strong><\/p>\n\n\n\n<p>Increasing the value of R26 turns this opamp buffer stage into a gain stage, making up some of the gain reduced in my other mods and smoothing out the decay of sustained notes a bit (as the different stages exit saturation at different times in the decay). &nbsp;Experiment with the value.<\/p>\n\n\n\n<p><strong>R26 &#8211; Add 3mm red LEDs in parallel<\/strong><\/p>\n\n\n\n<p>Diodes added in parallel with R26 turn this gain stage into a soft-clipping stage&nbsp;(via negative feedback), which I really like. &nbsp;They also decrease output level relative to the noise floor a bit, so I like to have a toggle switch to bring them into or out of the circuit. &nbsp;This is a great place to experiment with all kinds of diodes, particularly&nbsp;various colors of LEDs (which have different forward voltages, very approximately, from red&nbsp;(low) to yellow, green, blue, and violet (high)).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you want to take my &#8220;Simple Dog&#8221;
