EVERYONE should have a fretless bass,If you plan to use it for a MAIN stay ,then look for the higher end ones,BUT,for to use ob a few songs or just for your own ebjoyment ,then the lesser price ones are great,I love fretless always have,but they aren't to popular in alot of songs,and they have fx stuff,but i bought a FENDER JAZZ fretless,MEXIE,i had to put lighter gadged stringsmand miner adjustments,but i use mine for jazz,moldy oldies and songs that have fretless sounding bass in them, i LOVE it,and i can do just about everything you can do,except the popping thing,comes out a little weird,other than that,i can get my fretless growling like a BEAR
GOOD LUCK
