1 reverb11 1 year ago I ordered a bridge Ray Butts filtertron for my SSLVO. I installed it last night, and left the TV Classic in the neck (I've no reason to swap it). I haven't spent much time with it yet, but I have some initial impressions. 1) It measures about 4.28K and balances well with the neck Classic. 2) It is brighter, I think than the TV Classic bridge that I removed, but the brightness is somehow more musical to my ear than the top end of the Classic, which could sound a bit harsh. 3) The lack of potting doesn't seem to introduce any noise--granted, I was playing it through an 18 watt amp in my house, and not at Townshend levels.I think I like it, but as with all things, time will tell.
