Tom most likely installed switches to disable the chorus and echo independently, as well as minor tweaks to the clipping and EQ.

Mike didn’t mention this in that thread, but it’s also widely believed that DL used another device called the Rock Box by JHS, which was one of many Rockman clones to pop up around that time.

The JHS Rock Box was also sold as the Phonic Rock Box and Nobels Sound Studio. I had the Nobels one for a bit. Similar sound to the Rockman, and it has independent chorus/echo controls as standard, plus and effects loop and adjustable compressor, but takes some extra processing to get a decent tone out of it. Every so often I think I can detect the Rock Box in the album but I’m not totally sure...

My understanding is that they used the Metal Ace circuit.
I'll see if I can find out for sure....

That sounds right, and IIRC there were rumors that the Metal Ace was used on Adrenalize. I could easily be wrong though.

I just replaced the chorus echo switch with 2 slide switches. I had to remove the aux jack to proto type my idea. I was able to get each to turn on and off with a 3rd option of dry sound. I have small micro sliders on order that should fit into the 1" space required. If I can get these switches to fit, I will add this as a mod to my refurbished X100's. I may also consider modding customers X100's who want this option along with a refurbish.
