"The Sophia tremolo’s design is such a vast improvement over previous systems that it’s an understatement to call it the most significant tremolo system upgrade introduced since the Floyd Rose." Guitar World
From world-class Luthier, Gene Baker -- B3/Roscoe Guitars [Senior Master Builder for the Fender Custom Shop '93-'99] on his Charvel equipped CSL Sophia 2:92 Pro with the Global Tuner Pro with Dual Stabilizers:
"Playing performance it feels great, smooth, stays in tune ... Really like the sleek look and no rough or bulky edges to it.... As far as the dual stabilizer goes, it works and helps eliminate palm pressure to maintain pitch and pulls backwards nicely.... easy to feel and hear once the pistons come in contact with the body, there's an added tone transference throughout ..."
From premier luthier Rick Canton, Canton Custom Guitars and the "Jimi Tunnell Model" headless guitar with the CSL Sophia 2:92 Pro:
"The tone was a very noticeable positive improvement, much more fuller all over ... the trem really is the best Floyd type replacement out there today. Thanks again for all of your detailed guidance."
Jimi Tunnel, Steps Ahead, Tri-Lateral Commission:
"Enormous thanks to Rick Canton and Geoffrey Lee McCabe. You gentlemen are brilliant. NO ONE is doing what these guys are doing."
" ... the thing about trems staying in tune ... [plays and laughs]... I don't know what to tell you ..."
"the tuners feel ridiculous", "the simplicity of this thing and the precision ... " -- Jimi T
From Teddy kumpel, Joe Jackson's guitarist, etc., regarding his new Sophia 2:92 Pro on his Fender Japan 80's Strat:

There is no rattling of the arm at all, adjustment is also easy. It's really amazing gear!!... Thank you very much for this time!"

On the Sophia 2:22 Standard CSE Pro:
"Amazed by this tremolo system in the very brief time I’ve used it so far. Install was done by Ryan at Equilibrium Guitars in Somerville MA. Got the guitar back today. Playing for hours. Tuning stability is awesome. One thing I did not expect though, the sound is snappy as all hell, compared to the previous two tremolos. It’s blowing me away. Anyway, killer job with this 2:22! Couldn’t be any happier ...."
R -- Boston, Certified Luthier and Repair Technician
"It was great to have a chance to work with the bridge. It is very stable and B is really excited. Thanks for sending that stuff over and helping with my questions."

We got one in Thomas Nordegg's Evo — One customer sent us pic of his green Evo — he put on a chrome Sophia 2:92 Pro — so that’s cool too:)
