My EMG Xb was produced in 1933 from all I gather. By 1933, a lot of American 78rpm recordings were transitioning in composition to a much softer material, and groove depth and modulation grew much stronger. By the time the 40's broke out, records had lead-in grooves, even softer composition, and any additives (clay) in the disc composition may altogether have been done away with, making a disc that is softer, and more plasticine, yet offering SUPERIOR fidelity. By the 40's American 78's were being played with sapphire points on electrically amplified phonographs with a horseshoe magnetic or crystal pickups. I have noticed on some of my late 30's English discs that the composition seems harder, and they take to heavy play much better.
HERE IS MY QUESTION: I see a mighty amount of chaps over the pond on YouTube playing 1940's records on their EMG and Expert machines. There is no question that the diaphragm and horn system can amplify the signal, but >MY< problem with playing a 30's or 40's record with a steel needle is the ridiculously fast greying of the groove walls, and noticible wear after only a few plays. In the USA, playing 40's Decca brand discs on an acoustic steel-needle phonograph is looked down upon by some collectors. It was my stance for years that these discs were 1. too soft, and 2. didn't have the correct friction components to wear down a nickel plated needle to each individual groove shape. Moreover...the friction..... oh my. Some 40's discs have such deep groove modulation that they stop some single and double spring wind-up phonographs in their tracks. I have some 40's discs that were played just a few times with a steel needle, and when you look at them in the sunlight......it just breaks my heart.
So far I have been playing Brunswick, Columbia Viva Tonal, and Victor Orthophonic VE discs on the Xb, and a slew of good acoustic opera!!! They do sound great on 30's and 40's records, but it makes me queasy. Any comment?

PS: I will be more active in this Forum...adding my reproducer rebuild info on the EMG 4-spring as time permits.
