I have a 1997 Rose Morris Reissue with two low output toasters (in the 6k ohm range). I think the bridge can be a little too quiet and thin sounding, so I'm considering installing a Hi-Gain. I know that I'd like to convert it to a toaster top. My question is: if I want to convert the adjustable poles to alnico rods, is there enough bobbin to enlarge the holes to .250" and not damage the coil? If I recall correctly, the poles on the bridge position Hi-Gain have a wider spacing than the neck position... That being the case, would a neck position Hi-Gain be a better candidate? Thanks for any help guys!
