in a nutshell, compression takes the guitar signal, and balances out the volume level to some extent. so yung mahina pinapalakas nya, yung mashadong malakas hinihinaan nya to a value that you assign thru one of the knobs. very useful sha for bass guitars (i.e. boss comp/limiter), when oftentimes you have one string that keeps popping out (volume-wise), tas yung lower strings mo mejo dull tsaka lunod. sa guitar naman think john frusciante.. actually very useful ang comp whenever you play cleantone stuff kase 1)balanse yung volume mo across all the strings, 2) consistent yung volume kahit mejo sumablay ka sa pag-pick, 3)modulation and time-based FX (delay, flange, phasing, etc) actually respond better to a compressed signal. mas klaro yung tunog mo..
mejo limited ang use ng comp sa dirty guitar sounds because distortion/OD has somewhat the same effect on the signal. compression before gain equals mush if you're not careful.
SRV: i guess ayos naman yung tunog nya. I'm just looking for something a bit quieter than my CS3. djahe kase, naka-single coils pa ako. badtrip. i think deltaslim has the same problem..
