  • Page 4: General Guideline For Components

    General guideline for components  Capacitors: All values under 1nF should be ceramic disks. From 1nF up to 1uF should be MKT (foil/metal film capacitors) and over 1uF use electrolyte caps (or tantalum) 16V+ rated and watch out for polarity! In this build there are some deviations from this rule so we marked all capacitors with the required type in the table on page 3.

  • Page 5: Modifications

    Modifications If you want darker repeats then you can replace the C11 (15nF) with a higher value or make it switchable like this (middle position is stock value of 15nF). You are free to choose different values! Some people prefer another IC than the TL072. You could try a OPA2134 instead. Tap Tempo Daughterboard If you are planning on using a taptation tap tempo daughterboard (sold separately, contact your seller) then do not connect R18 and VR4.

  • Page 8: Troubleshooting

    Troubleshooting All PCB’s have been e-tested 100% in the factory, so there should not be a connection problem on the PCB itself. The board is not working (at all), what now?  Check if your 9V is plugged in correctly (and/or soldered correctly on the board). ...
