My understanding is the noise mods will help quite a lot with very high gain patches (OD1 high, OD2 High), (and also to some extent the MDRT transformer upgrade will help). When you turn the gain up that much you can/should expect it to be quite sensitive (e.g. ever tried a 1972 Marshall at full tilt, bit of a beast to control
, particularly with single coil strat PUs). What pick ups you are using also make a big difference (some are much more microphonic than others). The MP1 manual recommends (
When setting your Overdrive levels, remember that low levels followed by high levels produce more noise than the reverse. High levels of OVERDRIVE 1 will produce a distortion that has high frequency harmonic saturation, whereas high levels of Overdrive 2 produce fuller harmonic saturation.). When you run that amount of gain, everything you can do to help control it is valid/helps, i.e noise mods, noise gates etc. As Jarrod says OD2 @ 8 is big, with lower OD1 settings this will probably be noisy but hey it should work at OD1-10 and OD2-10 but it's not just the guitar signal being amplified here, also the noise floor.
