I tend to get a lot from John Petrucci, Joe Satriani, Marco Sfogli, and Andy Timmons when it comes to infuencing my amp tone. They are (or were) Mesa Boogie users at one point of another.
Here's my map for finding my amp.
1. Mesa Boogie - Tredplate Vintage
2. Cabinet - 4x12 Celestian Vintage 30 Speakers
3. Microphone - Sennheiser 421 paired w/ Royer 121 (for Leads)
4. Microphone - Sennheiser 421 paired w/ SM57 (For Rhythms)
