If the compressor is very important in Your sound, absolutely go for pedal. It will give more options and easier and faster to change options right under Your foot.
It's ok Your slap - no. You can live without it. I play fretless with a ramp from to my soupbar pickup and have no chance for slap. Actualy i never loved or learned slap.
Basschat is absolutely cool !! I remember some years at other site "Talkbass" but i was put out from it for too much trolling, but never understood what i did wrong. I think Basschat is better.
On the other way, people who want to buy a real vintage Fender can mistake, with no licenced papers and serial that doesn't count. So what You choose - sound and roudworn or oficial docs.
