When looking at the TV Jones website FAQ, I was pleasantly surprised to come upon this: "We recommend the GB 0520 ABR-1 bridge from allparts.com. The saddles are solid brass. It's a wonderful bridge machined from solid metal, not cast. Many enjoy the works of Tru Arc and Compton bridges as well - so do we." I haven't seen much if any talk about the Allparts bridge here, and it was refreshing to see the most hallowed Gretsch-style pickup maker call out a relatively inexpensive part (while also giving love to Tru Arc and Compton, who are well liked for good reason). I use wound 4th string sets, so I need string by string adjustable intonation. I'm debating between these TVJ-recommended Allparts bridges and trying to get a hold of some ABM2400 roller bridges from a U.S. source (to avoid the currently extended customs wait). Anyone here have experiences to share with the Allparts unit as an upgrade, particularly for a (1st generation) 5622T or mid-2010s Pro Jet (5435 and 5435T)?
