PunchinPreacher Posted November 10, 2005 Report Share Posted November 10, 2005 Hey guys! Correct me if I'm wrong, I've not had the chance to check them out, but the Takamine Volume pots on the Graph-Ex Preamps are active pcb mounted pots. Someone told me that they're rated at 47k ohms. Is it possible to step them up? Is it possible to find passive Pots that sink flush? Is it possible...? Thanks, PP Quote Link to comment Share on other sites More sharing options...
lovekraft Posted November 11, 2005 Report Share Posted November 11, 2005 What exactly is an active pot? Pots are pretty much intrinsically passive by definition. Perhaps they're using digital encoders instead of pots to drive a digital gain control chip? Quote Link to comment Share on other sites More sharing options...

I'm thinking that it needs power to do its variable resistance thing? Quote Link to comment Share on other sites More sharing options...
daveq Posted November 11, 2005 Report Share Posted November 11, 2005 Are they something like these : ? Digital Pots I thought about trying these things out a while ago but for guitars, I just couldn't justify it (other than just having fun).

ansil Posted November 11, 2005 Report Share Posted November 11, 2005 if they have a similar resistive strip in them then you could always scrape away some of the resistive material per R.G. Keen's article at geofex the secret life of pots. perhaps in the electronics section that should be required reading. anyone want to make that a pinned subject.
