Okay so I'm thinking of using some pretty thick strings on my old bass (so I'll still play it, opposed to my main bass, mainly using it for beating dropped 8 string guitars out of my frequency) and I'm thinking of using 165-145-125-105-85, which I would want setup either C#F#BEA or BEADG. My questions are do you think my poor amp could take it (Peavey TKO 65)? Would I need a new bridge (I know would probably I'd have to file the nut)? Can the wood take it (setup right of course, the woods are Mahogany body, maple neck, rosewood neck)? My final question is what is your opinion on this (keep in mind I would be going this low if it wasn't for the extremely low guitars in my frequency)?
