I have a set of L500's in my Les Paul that are the USA version (XL in bridge, R in the neck) and absolutely love them. I have them wired up to 500K pots. For my new guitar (Gibson SG Supreme), I will be ordering another set of L500's but this time from Wilde pickups aka Bill and Becky. What is the difference between the shielded and unshielded versions of the L500's? I really like the sharp top end attack of the current L500's I have in my Les Paul. I have read that the shielded ones with the chrome ring are a little softer in their attack and not as strong in the top end? Is this true? Or is the difference between the two so small that it's barely noticeable? Are the shielded ones that much quieter than the regular ones? The regular ones are already very silent and hum free. I much prefer the look of the shielded ones (I think the chrome housing matches the blades really nicely and looks cool), however, I don't want to loose that strong/sharp top end attack my current L500's have(which are the none shielded ones from USA not Wilde). What is the difference between the L500L and the L500XL? I have read conflicting info about the two. I have read from Bill Lawrence's Pickupology write up and as well from other people that as you increase inductance/output you lose high end. Some people have written that the XL is compressed while the L is more dynamic and has more top end and others have written that the XL is brighter and punchier and very dynamic. I have never played the L500L, but my L500xl seems pretty dynamic for a high output pickup. What exactly is the difference between these two models? On the website under wiring and tech info it states that models over a certain inductance range (like the L500XL) should be used with 500K pots or higher. For the L500XL, would it be better to use a 1 meg pot instead of a 500k pot? What would a 1 Meg pot sound like with the R in the neck position? I understand as you increase inductance you gain output but also lose top end. I want to retain as much top end as possible. Would a L500XL with 1 Meg pots sound similar to a L500L with 500K pots if the L500L is indeed brighter? There are a lot of questions here as there is not that much info or videos about these pickups. I have read almost every thread from every forum I have found about these pickups. Thank you.
