Please advise: How does the GuitarFetish Xavier XV880 Superstrat Floyd Rose Tremolo differ from the 2 different GFS Floyd Rose [fastloader OR dual locking heavy duty] Tremolos?

Also, please offer your full opinion on the XV880 guitar, especially at $169 [before S&H]. I wish it came with maple fretboard/jumbo frets/preferably scalloped. I know.

Also, if you can opine on their basses. How do they make active electronics work with passive bass pickups on their DLX bass?

Thank You. Respectfully, Ken
