Just thought I'd post some settings for those who own the first MG 100 watt head and can't seem to dial a good tone (like me for the longest time) Here are a couple good starting points that sound great with the master around 5. P.S. I play through either my Gibson LP Vintage Mahogany or my Gibson Dark Fire, and sometimes my Ibanez Art 100. And the OD/Distorted tones are usually on the lead pickup. Clean: Channel: Clean Gain: 3 1/2 Bass: 6 1/2 Middle: 6 1/2 Treble: 6 1/2 Classic Overdrive: Channel: OD 1 Gain: Set to taste Bass: 10 Middle: 10 Treble: 3 1/2 Contour: 0 Solid Rock: Channel: OD 2 Gain: 5 (Still, set to taste) Bass: 10 Middle: 10 Treble: 3 1/2 Contour: 0 Heavy Rock (Somewhat like Mark Tremonti with the right guitar): Channel: OD 2 Gain: 5 Bass: Anywhere from 5 to 10 depending on how deep you want it to sound Middle: 0 Treble: 3 1/2 Contour: 0 Metal: Channel: OD 2 Gain: As much as you want Bass: 10 Middle: 0 Treble: 3 1/2 Contour: 5 Light Bluesy Crunch: Channel: OD 1 Gain: 2 Bass: 10 Middle: 10 Treble: 5 Contour: 0 Add as much reverb and/or digital effects as you like, and don't worry about what these sound like at low volumes (anything below 1 1/2 on the master) these are good and solid starting points for your own individual tweaking at nice high volumes. Also, don't be afraid of adjusting you guitar's volume and tone settings to get just the sound you're looking for. I've found that on the Solid Rock setting turning the tone down a little bit can give more of a growl and less crunch and fuzz. Keep that in mind, that's what they're there for. I hope I was some help to somebody!
