can a big cap slow down the turn on time of a transistor biased to gate?

[Quackzed]

i've seen a few simple circuits that use a misbiased transistor for a gating effect... gated fuzz comes to mind...
my question is , is there a way to use a big cap to make the transistor not turn on right away on this type of circuit?
i know in compressors the cap value determines somewhat how fast the comp claps down on the signal, and was wondering if there was an easy way to do the same thing to a transistor that is biased to act as a gate... either biased too low (not enough current to turn on when there is no signal present) or biased to high maybee?
i figure a large cap in series with a small resistor to ground to slowly dump the excess signal?!
the reason im asking is ive been fooling around with octave designs to try to get rid of the attack of the guitar and have got some pretty strange sounds and am interested in a different method of removing the attack... not looking for a slow gear type thing, just a quick and dirty little circuit addition that might work in a transistor design... something where you whack the guitar strings and the transistor comes stumbling after... not necessarily slow or smooth... but simple
