No delay im sure...neck pick ups im fairly sure. This is what slash says via his website about his sig. amp...maybe a little different with the JCM 900...

" the dirty tone, the SLASH recommended settings are: Presence: 7, Bass: 7, Mid: 4.5, Treble: 7, Output Master: 6, Lead Master: 10, Input Gain: 6.5. The JCM SLASH Marshalls are used for a clean sound, too, when modified with KT88 output tubes. The SLASH Marshall should be tuned this way for the clean tone (SLASH recommendations): Presence: 0, Bass: 9, Mid: 3, Treble: 5 1/2, Output Master: 10, Lead Master: 0, Input Gain: 4."

That will give u a ruff idea. Hes uses reverb as well. i use to have the settings but lost em. The gear you use makes a big difference as well as your playing style.


Also remember to tune down a 1/2 step.
