Interesting find - the Slash #34 JCM800 mod...

[HTH AMPS]

I'm going to guess that since using a single cap instead of the shield wire was an option when these mods were created, and that there is some benefit in using the shielded wire over the cap.

I wouldn't be so quick to assume that.  The likelihood is that the Marshall guys thought, hmm.... connect the shield to the plate, or add a capacitor that costs money.  Catch my drift?

Well, if it were just Marshall we were talking about, and the cost of thousands of capacitors, I may agree with you, but; we're also talking about Tim and Frank, who HAD the option to use a small, single and safe capacitor.  Instead they used the hot-shield method, which (and I'm guessing here) MUST have provided something to the overall tone that a single capacitor did/could not.

One of these days I am going to swap the hot-shields for caps, and we'll see what happens...  It sounds so damn good that I hate to even mess with it.  :lol:

For anyone that is interested in doing this mod based on my instructions, and you're wondering why Frank Levi's #34 mod is so different than mine, it's because in order to acheive the #34 tone with Franks mod, you had to crank the amp.  The Master had to be set at 8, and Pre-amp had to be set at 3.  This mod enables you to get the #34 tone at bedroom levels with the Master Volume set anywhere from 1 to 3.

The settings I use for this mod are: P10 B0 M3~5 T3~5 M1~3 PA 7~8.

you could argue one way or the other all day - I really couldn't give a fu*ck, I know what I like and thats good enough for me, people seem to like my amps too, so thats good enough for me too.
