I'm forming the opinion that the MannMade 2300 is an amazing upgrade. perhaps we should just put it in the category of different tones available. because the standard bridge is also very nice. however I just purchased 2018 Experience Paul's guitar, and it seemed like a really cool slurry tone, like smashing pumpkins tones, P90 tones, slightly different than I remembered my 2013 Paul's guitar. I started comparing it to my core Mira, which I had previously upgraded to the 2300 mannmade, and it really seemed to bring that guitar to life. so I went ahead and put the MannMade 2300 on the brand-new $5000 Paul's guitar, fully prepared to immediately swap it back to the aluminum,in fear. but holy crap what an amazing improvement. I swapped it back, once to confirm what I was hearing. it appeared to me that the aluminum bridge allows all the strings to communicate with each other too much creating that slurry tone. the individual brass saddles have created fantastic high definition note clarity. it's such an amazing guitar now all the other guitars are in the closet. the aluminum is just a different tone for me. is it a placebo effect?
