    A clean, quiet pedal
    Pros: Excellent Sound Quality,Compact Design
    Cons: Limited Selection Of Effects

    Excellent for making changes in the attack and sustain of your guitar. Not so necessary when using higher powered amps and drive pedals. It does an excellent job of filling and pushing the sound of my electric 12-string.

    play louder and longer
    Pros: Compact Design,Responsive,Excellent Sound Quality
    Cons: Limited Selection Of Effects

    great pedal. let's you squish your signal (turn the loudest bits down so you can turn the whole thing up) handy to smooth out dynamics, add sustain, or for use a s a boost. been in my pedal board forever.
    Pros: Compact Design,Responsive
    Cons: Limited Selection Of Effects

    i used this mostly for increasing sustain,
    if you push this pedal too far you will end up with a very loud and hissy signal.
    with a decent noise supressor you could get this pedal to drag out your notes a lot further than normal, but it might be too much effort for the desired effect.
    theres a lot of ways to make this pedal sound back when dialing up, but once you get the hang of it you can get some sweet droning notes. i used the pedal mostly for draging out overdriven notes, sounds sweet in some low end!

    Compressor for all instruments!
    Pros: Excellent Sound Quality,Versatile

    I have found the Boss CS3 to be a great universal compressor. I play a lot of acoustic guitar and bass. It's nice to take my StompBlox pedalboard with a tuner, compressor, DI and use the same rig for both of those applications at church. I have several friends that use this pedal in their electric guitar rigs as well. Punch, soft compression, sustain, this does what a good compressor should do very well. Great build quality, can't get more standard than Boss pedals.

    Good pedal
    Pros: Versatile

    This pedal works well to sustain notes.
    The compression is a bit lacking in depth.
