Seems to work well with my i4 instrument input. I&#8217;ll have to build a few shielded piezos to get a better understanding of its quality. The build was relatively easy and I sourced a matched 2N3819 jfet pair locally (should have found a more sensitive couple but went for 11,6 &amp; 11,7 Idss). Also&#8230; Should have fitted the 1,5k (R3) resistor I used with a 1-2k trimmer for balancing the transistor bias (the balancing process is detailed in the <a href=\"https:\/\/zeppelindesignlabs.com\/product\/cortado-balanced-piezo-contact-mic\/\">Cortado preamp documentations<\/a>). But I&#8217;m happy with this as is&#8230; Perhaps for the next build.<\/p>\n<p>Fitting a Neutrik NCJ6FIS combojack in a Hammond 1550A case took filing but worked well in the end. Added a belt clip from an old W\u00fcrth tape measure so that I can keep the unit on me during performances. A neat and small package! I&#8217;ll etch some descriptions (using ferric chloric acid!) on its workings to the case before its done. I&#8217;m dreaming of building a stereo-pair which could be fitted to the two inputs of my tascam dr40.
