So im lucky enough to have been playing my 2005 Gretsch Hot Rod with TV jones Filtertrons a little over a decade now. Ive always thought that guitar was just perfect! the tone was just unbeatable for me. However... Last month, I bought an EVH Wolfgang for those high gain dive bomb kind of songs. I upgraded the pots, input jack, switch and pickups and yes it was much more vibrant but... after swapping the 37mm Chinese pot metal tone block for a solid 42mm Brass block, the guitar just rings for days!!! The sustain and chime is outstanding especially on cleaner sounding songs...So much so that my Gretsch now sounds a bit on the muddy side in comparison and just does not sustain as I would like it to. Both guitars have D'Addario Pro Steel 9-42 strings. (although I do use the Dunlop BFG 7-38's sometimes on the Gretsch). The Gretsch still sounds great but I would just love to get it to sustain and chime a bit brighter. Any thoughts? Ive seen some comparisons using Compton chambered bridges or the Tru-Arc bridge which may help but there really aren't that many sound comparisons out there that I am aware of. Thanks for the help!
