One month after I got my Special Edition Electric Blue/Alnico Blue DRRI in 2010, I did the Fritz Mod, putting the channels in phase and adding reverb/tremolo to the Normal channel, sans bright cap. Since then I have played by jumping the channels, using all controls. Today I hooked up my A/B box to directly compare the bright cap, with and without. I set both bass controls at 8 and both treble controls at 2, vols at 4. I used my Carvin humbucker guitar and plugged directly into the amp. Switching back and forth I heard very little difference in the two channels with my tone control settings. The Fritz Mod was a lot easier to perform than pulling the front control panel getting to the bright cap. Just a FYI on a rainy morning.
