I don't post here all that much, so please excuse me if this isn't the right place to ask this...
I've been reading about the "one wire mod" after seeing/hearing the Rhoads signature amp from Marshall. It just so happens that I'm gathering up parts for a 1987 clone project. Will I be able to perform this mod when the amp is finished? If so, what exactly do I need to do?
Again, I apologize if this is not the right place, but I know it's an easy and well documented mod. Just want to understand it.

Head over to the MetroAmp forums. It isn't my area of interest, but there is lots of activity on the 1959RR and one wire mod.
There are lots of discussion threads on the one wire mod at the MetroAmp forums--this is just the newest one. I've never touched anything like this, don't like it on a personal level, and haven't bothered to do anything more than glance at this stuff, so I can't vouch for the accuracy of anything, but some of the guys in that thread are pretty reliable, so go have a look.
i just did one to my sovtek mig50. doesn't add a whole ton of usability though honestly.
If you do do it you need to switch out the cathode bypass cap on the stage you cascade into. This makes the cascaded preamp look like a JCM800 now. Otherwise the distortion is out of control feedback, and totally unusable even at low volumes.
I put two volume controls with switches on them so i didn't have to drill any holes in the chassis. Wired one to implement the one-wire mod, and the other to bypass the cathode cap. If you're getting together a project parts list, add some pots with switches and then you can implement the mods after you're all wired up.
