I am having a problem with my brand new Stereo Polychorus whenever I use the delay function – either in Chorus mode using the Tune/Delay knob, or in the Double Track mode.
There is a background high pitched trail of harmonics which follow every note, a bit like a steel drum which is “pinging” enough to be annoying (except when I want a slightly steel drum sound obviously). Sounds like some ring modulation is creeping in? It makes no difference whether I have the Feedback knob rolled completely off or not.
Any suggestions or is the unit faulty? Thanks if you can help.
Have a look also for all these power supply issues at the CIOKS power supplies (manufactured in Denmark) – DC 10, Power Bitch, Pussy Power etc, many models have isolated outputs, a range of voltages from 9V to 40V, and most models are designed for specific pedals or combos of pedals such as EHX. For example I can run my 24V EHX pedal off 2 x 12V isolated outlets using a 2-into-one series flex with positive center 2.5mm plug which comes with the bundle of flexes included with the power supply. I can also run higher draw (say 170mA) 9V pedals with 2-into-one parallel flexes off 2 100mA outlets. OR I can just plug high draw pedals into some of the higher current single flex 9V (standard center negative) outlets (300-400mA) which some of the models have. Hope that’s some help.
