Check this out... I have just finished my newly designed BRASS sustain blocks for PRS SE and PRS S2 trem equipped guitars ! Direct replacement with no mods. Increase tone... sustain... harmonic content... The Block will be available within the week from MannMade USA (that'd be me ). You will be able to order the upgrade block directly online at John Mann's Guitar Vault (www.GuitarVaultUSA.com) Sound / video files to follow shortly... This photo is a 2013 PRS SE Santana with the original PRS SE bridge top plate bolted on to a MannMade USA Brass Block, MannMade USA polished saddles, MannMade USA STEEL mounting screws. The bridge now uses a US PRS or MannMade USA arm.. NOTE: This is an upgrade part only. As always... MannMade USA parts are for sale only as after market parts to be installed by you or a qualified tech.
