Question: JP16: Aluminum Tremolo block?

Today, I switched out the 10s to 9s and set the guitar up accordingly. Odd thing i noticed, the tremolo block on the Floyd Rose 1000 Pro appears to be aluminum. I don’t know if this is good or bad.

Most of my patches on the AX8 are set up for my Axis (Floyd). When I play the patches on the JP16, they are noticeably ‘quieter’, and I get lackluster sustain past the 12th fret, unless I turn on the +20db boost (which i’m assuming I don’t need to have turned on all the time).

Is the aluminum trem block on the JP16 killing the tone, or am I just expecting too much from the Sonic Ecstasy pickups? The JP16 is so beautiful and comfortable, I really want to love it. (Btw…nearly all of my other guitars sound just fine with the Axis patches, just slightly different depending on the pups.)

Any advice, greatly appreciated
