I was at the store earlier today, and I was bored so I just picked up a Professional Series bass and I started playing fingerstyle "aight that sounds ok", then I started slapping on it! "MY GOD!" The slap sound on this thing is great! I was just wondering, on the higher end spectors (USA). how do they compare to the professional series? Specifics please! Thanks! Oh ya the harmonics on it are great too, they jump right out of it!
