i just got hold of an ODB3 and after years of not getting one becuase
of ppl on forums saying it was rubbish, i am really pleased with it.
I have owned a fulltone bass drive and i think that its not so hot, it did have the TS9 mid hump and loss of low end, so i had to re -eq my amp all the time.
I think the problem with ppl not getting on with the ODB-3 is that if you dont turn down the GAIN to near zero you are going get distortion & fuzz, but its really simple to follow the manaul and dial in an SVT overdriven sound.
SO i guess that's why FLEA uses one and sometimes famous ppl are actually better at choosing gear than strangers on a forum.
Also jamie cullums bassist uses one and he is a jazz virtuoso, so you have both ends of the spectrum covered, dont listen to forum ppl all the time, make your own minds up and chek out actual real musicians and the gear they use, you'll learn more, i did!
take care guys
