that's the BOSS link for their pedal board think.
i've tried several different pedal brands, and i've come to love BOSS. they sound great and they're durable.
thanks to buying and re selling on ebay, i've owned
DS-1 Distortion
DS-2 Turbo Distortion
MD-2 Mega Distortion
MT-2 Metal Zone
OS-2 Overdrive/Distortion
DD-6 digital delay
BF-3 Flanger
CE-5 Chorus Ensemble
CH-1 Super Chorus
PH-3 Phase Shifter
OC-3 Super Octave
CS-3 compressor/sustainer
some i liked, some i didn't. my favorite is the DD-6.
If you mess around with that link above, you'll notice they only let you put the pedals in a certain order. it does effect your sound sometimes if you put your pedals in a certain way.
Sound 1: Guitar->Distortion->delay-->phase shifter
Sound 2(i don't like this): guitar-->distortion-->phase shifter--> delay
This is hard to understand til you hear it. in sound 1, the phase shifter causes your delay to have a flange like sound. so the delay sounds like it's going up and down in a wave.
in sound 2, when you "delay the phase", it doesn't sound like one wave, it's broken up. try it in a music store.
if you're wondering about multi effect processors, totally disregard everything i just said.
after much fiddling about, i prefer my guitar to do this kind of pedal set up
Guitar --> Compressor/Sustainer --> Distortion -->Delay --> Chorus, Flanger, Phaser, or wah --> extra Delay pedal when i have it ---> amp.
but them i came across a marshall amp... and just went guitar--> amp. that distortion just rocks.
oh, don't bother with pedals if you have a small amp like a Peavey blazer 158 (8 inch speaker). you won't hear to real quality of the pedal.
i don't like multi effect pedals. if you go to live shows, you'll notice most guitarists use a bunch of pedals, not a multieffect board.
