noiseless distortion

[changes]

i have tried an emulation of a high gain amp(with the way the rog guys introduced) so i get really killer sound but with lots of background noise(hiss)
any ideas how to remove all that???

also does anybody have a schem for the marshall dsl 401
and any good DI for my el/acoustic guitar???

Sure.
(a) use low noise amplifying devices e.g. 2N5088/2N5089/MPSA18 or the equivalent in euro or Japanese series for bipolars, and low noise rated JFETs.
(b) use low noise metal film resistors in at least the first gain stage, if not all stages
(c) use low noise biasing techniques (I did a description on "noiseless biasing" in this forum, do a search)
(d) use new (not reclaimed) electrolytic capacitors with low leakage
(e) use good soldering practices to ensure no cold or partial-soldered joints
