Turning reverb and chorus off on x100

[RockmanCentralBob]

Great, thank you for the help! I will give this a try. But now you’ve got me thinking bad things... a similar switch in the correct location is all it would take to throw in an effects loop?

Yeah, pretty much.
It's just a matter of deciding what you want to use it for and that would probably determine where to place it in the circuit.
For example, you could add a loop before the distortion stage and use it for a pre-distortion EQ loop.
And/or you could add one after the distortion and before the chorus/reverb sends and use it for a Smart Gate and/or a post distortion EQ.
For something like that, I probably wouldn't even put it on a switch... just add TRS jack(s) and hard wire it in since you probably would want it in all the time. If you use the right female jack, there are some that will automatically bypass the loop if you don't have anything plugged into it.

I was thinking the most interesting place to put it would be after the compression/controllable gain but before the distortion so I could put an overdrive to drive it harder, what do you think? Is it easy to see where in the circuit this would go, and would it make sense to wire this to the two headphone jacks? I’m using the large output so I don’t need those.

In that case, you could have both pre distortion and post distortion loops.
Use one stereo jack for pre send/return and the other for post.

Is it easy to see on the schematic where this should go, to be post compression? I’ve tried looking at the schematic but can’t figure out which part is the compressor... best guess is that it goes on the downstream end of the circuit that bridges the selection of the different amp modes?

If you have the schematic, the TP1 is just after the compressor.
So you could VERY CAREFULLY lift one leg (or snip) of C135 (the side that connects to C107, R169, R111, etc) to add a pre-distortion loop.
On Rev10 boards, it looks like C135 may have been removed (or moved and joined with R112A which is a 560 ohm resistor).
So you woudl have to lift (or snip) both C135 and R112A in order to add the loop.

If you are not experienced working with electronics, I would NOT suggest you attempt this though.
You could very easily damage C135 and then you'd be screwed.

Honestly, I think it would be overkill.
I have articles with Tom and he said that when he was working on Third Stage, he would use an EQ before the X100 to change tones. I think he still does that even now when recording with the Rev 20 Sustainor. In photo's I've seen of him in his studio, there is a 10 Band MXR EQ just off to the right, easily within arms length, that I'm pretty sure is set up for this purpose.

And for What it's worth, I do the same thing....I have a 10 Band MXR EQ after my guitar.

Really ? Whats Montages? What Destructions ?? FX Switch have "non official dead position" betwen Norm and Chorus off or betwen Norm and Echo off. In this Position is sound without Chorus and Echo !! Jesus ! This trick is in Czech Republic very popular!

I modify Rockman X100 headphone amps to switch between Chorus, Echo, Dry and Chorus/Echo.

One trick with the X100 is to use just the left channel and select the chorus mode with echo off. The way the internal mixer is set, the left channel is mostly the dry signal.
