“I’ll tell you how to dial in any amp in the world and have it sound as good as it can. I dial any in amp like this, because I do a lot of fly-in gigs, and I’m not always able to take my own amps. Usually it’s a Fender ’65 Twin Reissue, or the Hot Rod amps – sometimes a Marshall DSL. But whatever it is, this is how it works for me.

“You’ll find that every pot has an obvious cusp point in its rotation – every single one – where it goes from not doing much, to where it really kicks in. So I sweep through the pots one by one and find those spots. All amps will do this – bass is especially easy to hear... nothing, nothing, nothing, then bang, there it is!

“Gain is just the same, master... and so on. Maybe reverb not so much – just put that where you like it – but all the others have a strongest sweep point in the rotation, so I find it, and that’s where it gets set! It’s the same with any pedals, all drives and tones – that’s how I set my Providence SOV-2 as well, for example.

“If you do that, the amp is set as evenly as it can be; not too trebly, not too dark. With everything set right on the cusp, you can push it over by digging in, or pull it back by playing softer. It makes everything really responsive and sensitive to what you do. The rest is up to you!”
