And by the way, i mean the american vintage fender trtem, not the MIM or anything else but the ones that came on the AVRI and probably the same one as on the pure vintage and AO lines. I assume they are all the same steel block trems. Anyways, i have the callaham and have used it for many years. But i am curious about the fender and how it compares sonically. The Callaham is very bright, yes, but it's also very great sounding aside from that and of course amp settings help to offset brightness. It's very harmonically right sounding, but i'd like to hear from anyone who's used both hopw the fender stacks up as tone goes.Not just "better" or "worse" but in what way....brighter, darker, as harmonically complex or not, etc etc. Not concerned with performance like tuning for example as i don''t use the trem much, but i'm not sure if they are drilled the same for the strings which can affect tension. Is the fender drilled shallow, IE: longer strings or deep, shorter?
