it is possible that 'pedals' are not necessary. i have a digitech rp 70. if i am willing to look at several levels of 'control' on it, i can find sounds i like. are they as good as separate pedals??? honestly, i can't hear all that jive that some people hear in pedals and amps. some of it is fantasy, i think. a bunch of people will disagree with me...i don't care. if you try a multi-effect pedal (zoom's low priced ones are pretty good sounding to-do a net search for reviews of multi effect pedals). i think there is a culture of 'gotta have'; it is competitive with 'what you got? i got better/more expensive/more 'in''. that culture doesn't do much for my playing.
if you buy one of the low end multi-effects boxes, you may be able to at least find out what effects you like, and which you don't. personally, i don't much like most chorus effects...maybe you will find you don't like overdrive, or metal or digital delay...but it's a lot better to have some idea where you are going than to order a grand's worth of pedals and realize you don't know where you are.
