Well, Slash used the bride pickup rolled back tone to 0 for SCOM actually ...
and solo's are simply a mid boost in the EQ pedal stage... in the FX loop for the best output.? You'll find only a small amount is needed.? Too much and you'll feed back like a fucking bitch!
dont give out advice unless its correct! slash uses the neck pickup for scom's leads (minus the 2nd half of solo and outro) and the tone is rolled down about half-way or maybe alittle bit more depending on the guitar and how new the strings are...........
