Disclaimer, I'm a bass player, not a guitar player! My friend wants to sell me a Agile AL-2500 12 string Les Paul type guitar ( from Rondo Music) and he told me to make it brighter sounding, I should replace the neck volume pot from 500K ( that's in the guitar now) to 1 meg, lower the pickups, replace the cap(s) with a lower value (high pass?), use "bright strings", and replace the neck pickup with a P 90 type. Can anyone recommend a pickup with more high end without breaking the bank? He also told me Mahogany is a "treble sucker" and that's what the body is, along with a flame Maple top. Will be using the guitar in my home studio only. Thanks in advance!
