I have seen many blogs with people trying to get Eric Clapton's "Beano" tone used on his Bluesbreakers album with John Mayall in 1966. I am sure that many people have found a gear combination that will get close to this sound. With the POD HD400, I made this combination of gear and settings: Marshall J45 amp model with default settings. I changed the Reverb to Chamber with Pre-delay 0%, Decay 50%, Tone 50%, Mix 20%. It is thought that Eric used a Dallas Rangemaster box which has an input mid-hi boost shelf and an output mid-hi boost shelf, both at around 400 Hz, so I used the Parametric Equalizer on FX1 set to Lows 32%, Highs 65%, Frequency at 44%, parametric band Q at 50% (12:00 position), Gain at 60% (1:00 position). I played a 1980 Les Paul Standard, Bridge pickup, through the clean channel of a 50W Music Man amp with two ElectroVoice 12M speakers, one open, one closed back, Volume on 6. I also had a clean 120W super-clean transistor amp fed off the output transformer of the Music Man into the power amp, not preamp, with a 4x10" closed-back cabinet. The rig sounds pretty much like a Marshall stack. Any clean amp and stack would probably do. The sound is pretty close to "Beano", and it is also useful on "Crossroads" by Cream, at least to my old ears, as I played that song in 1968. Just my two bits worth.
