[sdiy] MN3207 and MN3102 Reissues (Boss DC-2 Mods)

[Gregg]

hey mike,

what mods did you do to the dimension c? how does yours differ from stock?

i'm a total beginner to this diy malarky. if i wanted to improve the 
sound of my dc-2, i.e. less noise/higher quality etc, what would i go 
about changing first? would it be possible to just change the MN3207's 
for MN3007's for a better s/n ratio? is it old enough to benefit from 
replacing all the capacitors?

chuck us some links for these guitar fx newslists where lots of info is 
around!

all the best,

gregg.
