Marshall Jackhammer (od mode) is my fave for many years now. Truly the jcm 800 sound in a box, quiet, real and well built. retains clarity like no otjer and no fuzz fizz but real od.

These are always taste issues, but I can say I have owned or tested about two dozen ods and jack always wins. might use some other for a while, always get bacm to jackhammer.

With an ss amp hlwever, I had thks dod tubefx100 or something pedal, which was downright incfedible with roland cube for instance. just superb...but didnt work with tube amps.
