The middle one is with both pedals, I don't think I was clear about that. They Crayon definitely has a lot more coloration than just the Archer, and when stacked, it's a really fat lead tone. Until my name comes up on the KoT list (it's been on the list for just over a year), I doubt I'll remove either the Archer or Crayon from my board, or add any more ODs. Once the KoT arrives, I have a feeling it will end up replacing the Crayon.
Re: Please tell me about your favourite transparent overdrive
JHS Morning Glory is really nice. I haven't used it through a Princeton, but I have used it through a Bassman and a Twin Reverb with a Strat and a Tele to great success. I think the newest version even has an option for the red button switch, so you can toggle up to the next gain stage with a foot switch.
