you can't go wrong for $100
it also has a kinda drum machine built in *LOL*
in addition the digitech website has a Patch library for the RP series effects that easily give settings that recreate the sounds of lots of artists
even creed, staind & whatever other one you mentioned are all here
check it out
DIGITECH PATCH LIBRARY

still kinda wondering if these things are actually detrimental in a way to beginners cuz they might not get a strong sense of effects theory tho
happy holidays
