Floyd rose question
I was just reading a review on harmony central, of the new charvel san dimas superstrats.
A few guys said they will upgrade their Floyd rose pro to a floyd rose original.
When i looked on the floyd rose site , the only difference i see is that he engraving logo is different - but then i noticed the pro has string spacing of .400 inch and the original is .420 inch.
Im wondering, after spending so much on my charvel, is it really worth upgrading , or should i just put the time and effort into the metronome practising, where it counts !
