Aloha, thinking about a 7 string but i'm wonderin about fretboard material;what's the difference in tone and durability( using roundwounds)between purpleheart and phenolic.i know everything else matters too like body woods,pups,playing style,rig,etc.My favorite Bass is a 76 MM stingray w/a Moses Graphite fretless neck,Basslines pups and preamp.Iknow its a bolt-on,and im looking to buy or build a 7 string neck-thru..what i like about the MM is i can make it mwah,cry,sing,or spit fire...i can get a great slap tone also w/a pull of a knob(real versatile)im wondering if its possible to get a great slap tone from a 7/neckthru,and what type of woods you would suggest to be able to make all those things happen.i know there are some great mult-str. players out there and i would love to hear from all of you!! please include the bass youre playing now,what type of woods/electronics,what you like about the combo,what youve owned in the past and how long youve been playing!! p.s. looking for a used conklin 7 or warrior 6 fretless!!! thank you for your time!!!!!!
