Members CHOUTMUSIC Posted February 20, 2007 Members Share Posted February 20, 2007 Just curious if anyone has experience with perhaps adjusting the trim pot to maybe mellow out the sound a little? Possible? Or what does it do? Link to comment Share on other sites More sharing options...
Members Zlandicar Posted February 20, 2007 Members Share Posted February 20, 2007 I think there is, but I don't have mine at hand to check. Either way, you can mellow it out big time by removing R28. It will be much more subtle then. If that's not enough, C11 and C12 (I think) also work. http://diy.erikhansen.net/phase90.htm Link to comment Share on other sites More sharing options...
Members andreas Posted February 20, 2007 Members Share Posted February 20, 2007 Indeed - if you want to tame the RI Phase 90, removing R28 will do the trick. Don't mess with the trimpot - moving it out of position will usually only cause the phaser to stop working, and getting it back just so can be really hard. It's hot-glued for a reason... /Andreas Link to comment Share on other sites More sharing options...
Members dZjupp Posted February 20, 2007 Members Share Posted February 20, 2007 if you truly know the real sound of the phase 90 then don't be afraid to mess around with the trimpot, i did. you can mellow it out or what not but you will find that it really does sound the best with THE phase 90 sound. as you move through the sweep on the trim pot you can def tell where the sweet spot is.

Members t_e_l_e Posted February 20, 2007 Members Share Posted February 20, 2007 the trimpot is for adjusting for the sweep spot. turning this and your phaser will not sweep any more..., you can fix this by turning it back again.as far as i know all phase 90 have this trimpot inside due parts tolerance the sweep spot needs to be adjusted for every unit seperately. it's good know that this is in there, if your phase 90 is not sweeping anymore (cause of heavy giging or transportation aso.) it's an easy fix to find the sweepspot again with a little screwdriver for changing the sounds you ahve to look for the mods describe in the diy sites Link to comment Share on other sites More sharing options...
