OK,
You guys have really cleared up my thinking on this issue.
thanks!

Thanks you guys!
lots to think about...

what about one of those pedals with a tube in it.
Vox makes one with multiple effects. I don't really care about the effects, I just want a little reverb and some nice warm tone, but something like that. maybe a kit or something.
any thoughts?

OK,
Looking for opinions on a good way to make the G-100 bluesy.
(Bluesy to me means nice and warm and slightly over-driven)

Foot pedal?
anyone have a home built that does the job?
Tube preamp?
mods?
I tried the Digitech Bad Monkey (Me no likey) very mechanical sounding.

This is the G100-115 series 1 if that makes a difference to anyone. 
Thanks,

OK, sound great!

thanks for your input and  comments

Cheers,

So...
I can't tell if that is good natured ribbing or something else.
Is there a problem? 

OK,
I wired the inputs as described in my "updated" section of my first post on this.
It works find so I will call it a win.

Is anybody seeing this?

Ok, getting used the way this works. I appended my response to my original question.
My Bad, as Buffy would say...

Hello to all
I need to install new input Jacks in my Yamaha G100-115 series I, (stripped threads on the jack making for bad connections.)
I have downloaded a couple of different schematics but am not fully understanding them
I think someone else has been in here before me and it doesn't seem to go with the schematic.
From the schematic it Looks like the NC connection on the low input just goes to ground but the NC on the High input just runs into the Tip of the low input connector?
Could someone point me in a direction,
Thanks,

OK update...
with photos

Looks like the High and Low jacks TIP gets grounded through the NC connection which is wired through the "High" jack ground connector. The "low" Jack has a wire, attached to its NC connector (see photos) that was covered by a bit of shrink tube, This was broken when I opened the chassis but it makes sense to me that it just connected to the NC of the High jack to ground the Tip of the "Low" Jack.
The High tip goes to I1 and the Low tip goes to I2 and the grounds just tie together on the board
I don't know if you can see it on the photos but it looks as though the wires have been re-soldered to the board
so...
is this the correct configuration?
The Left most jack is the one I replaced to begin with. It doesn't allow the plug to fully engage so I purchased another jack also pictured. will this be adequate for this application?
The original Jack is pictured out of circuit for reference

thanks,

J M,
thanks for the info, I appreciate it!

Hello to all,
this is my first post here and I have a few questions for you guys.

I Have a Yamaha G100-115. I believe it to be a series I. It currently has a Peavey Scorpion S15825 installed in it and it has Surprisingly warm tone. It came with the original (blown) speaker? Yamaha JA-3802 included with the purchase. would it be worth fixing the 3802?
I see them listed as bass speakers frequently and also as organ speakers too which leads me to believe that its kind of a catch all instrument speaker rather than a guitar specific speaker

I understand that the Peavey is kinda middle of the road "guitar amp" speaker and I am wondering if I could do better.

what would you recommend to bring out that nice warm tone?


Thanks very much,
