Personally I don't like moving my hand up and down the neck too much, I'd prefer to just have as many strings as possible so my left hand barely moves. Gonna need 24 strings now.
Well, you just need to add a nice chorus pedal. And maybe a compressor too. You dont need a distorsion effect, an overdrive will be fine. Now, just get a flanger, an octaver, get a nice cab to match that new tube amp and you will be all set! Oh and btw these strings are looking old, you might wanna get new ones since you're getting a new fretless bass anyway.
My guitar gear looks eerily similar to the first picture. Many guitars (not quite that many, but too many), several amps, and a whole bunch of pedals. I have separate pedalboards for different kinds of music all set up with my favorite settings marked so I don't have to think too much on stage.
Plus I own a Gibson EB-0 bass that was passed down to me by the guy who taught me how to play when he died and a Trace Elliott bass combo that's falling apart. They sound great. No need for anything else.
We use effects pedals in prog metal all the time! 46 and 2 was the first song I learned, and it uses a phaser. Also, almost all the bass Daft Punk makes, is run through an effect.
Standard stuff like a compresser and a sound gate can be nice too.
