apples vs oranges, right? i was all set to get an mim P as my first bass ( i like that classic rock sound), and then along comes a deal on a new mtd grendel for $600. i figure as a beginner i probably won't appreciate much of a difference, but i'm a sucker for a deal. should i cough up an extra $250 for the grendel, or stick with the P? thanks for the help!
