Yes, the Bare Conductive pen wins on price, but with selling points like “water-soluble” and “removable” it doesn’t sound like it would be a contender for longevity. It may be suitable for a keyboard that never leaves the confines of a climate-controlled studio but not for gigging at a seaside resort or other high-humidity area. Since it is black, I assume the conductive component is carbon.

Disassemble, clean the contacts in the strips and pcb with isopropyl then lightly dot each charcoal pad with conductive ink. This has been my method, 6 synths so far, one being the prophet 600.

Just watched the video. He certainly did have problems with the bottom two strips and mentioned they might be prone to being fouled easily if a little grease gets on them or something. I would have liked to see him test those strips again after cleaning them with alcohol, in case he did get them dirty while installing. Certainly silver is much more conductive than carbon but I haven’t seen any reviews that report back after a few years to talk about longevity. I can’t say that I’ve tried any of the pen type silver applicators, just the little jars of fairly thick goop. That one he was showing was the MG 8420 ($27.78 on Amazon). Caig also has the CircuitWriter CW100P for $20.34.

oh wow..... those are the 'whole enchilada' then?? i thought it kind of pricey just for 'dots' alone! in the tests done with weigel's 'dots' this guy 'syntegrator' on youtube found them to be inferior to the liquids... though that's just one test but makes me apprehensive...
