I tried this method but mine is a KLM-368A instead of a 368.<br />I think I might have done something wrong b/c there is no sound coming from the Polysix. I'm very new to electronics but I HAD to try this since the attacks on the p6 would get much faster. Is there any way you could help out with this problem??dododododoohttps://www.blogger.com/profile/05623582696095278815noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-92046495884603132432019-12-03T08:36:16.406-05:002019-12-03T08:36:16.406-05:00No, the main lowpass filter for each voice is a co...No, the main lowpass filter for each voice is a completely different part of the circuit. The performance of the main lowpass filter is completely unchanged.<br /><br />This modification focuses on an extra global filter that is peculiar to the Polysix and is not accessible or visible to the user at all. I believe that it may have been added to manage hissy noise added by the effects section, but I would rather listen to a bit of hiss than to have my sound be deadened even just a little bit by this circuit.<br /><br />YMMV.Chiphttps://www.blogger.com/profile/10352943033779293161noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-60666727217467120672019-10-09T03:00:10.527-04:002019-10-09T03:00:10.527-04:00But does that mean you lose filter cut off control...But does that mean you lose filter cut off control?Marcelo Mortimerhttps://www.blogger.com/profile/06308349582668651375noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-37150104764104418342018-10-15T09:36:25.511-04:002018-10-15T09:36:25.511-04:00I would suggest another Mod.

It's possible to increase the gain of the first stage of IC11 by increasing the Resistor Value of R106.<br /><br />You could even put a 500K Variable Resistor in series with the original 330K R106 and mount it to the Front Panel. That way you could keep the original character of the polysix by simply leaving the Variable Resistor at Zero Ohms or dialing it up to 500K for more 'Sizzle' when required!Anonymoushttps://www.blogger.com/profile/13195284615375234359noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-62786495185553080722018-02-19T20:21:08.686-05:002018-02-19T20:21:08.686-05:00thanks man. polysix now sounds better than ever. thanks man. polysix now sounds better than ever.

While I did come up with the idea to force the filter open via Q14, it was Tony of Oakley Sound who had the audacity to suggest that it actually get removed and who suggested the jumpers J28 and J29. I then took his ideas and re-formulated them as a non-destructive mod. It's an example of the great things that happen through the free sharing of ideas.Chiphttps://www.blogger.com/profile/10352943033779293161noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-34508674127065787202013-07-15T19:14:42.687-04:002013-07-15T19:14:42.687-04:00Great work!!!
