Hey, so I was trying to get a similar tone to Gary Moore's still got the blues, using the plexi trebble patch. I just switched the amp to JTM 45 and used a fat rat drive (to try and come close to the guv'nor originally used by GM). I ended up with an awesome lead sound, which clears up nicely, has a nice singing sustain with excellent note bloom etc. I was very happy, until I noticed that when I played the D string at the 12th fret using the neck humbucker, I was getting some kind of strange overtones, like a constant ghost note ringing... I tried the following to solve the problem:
Professionally set up the guitar (all of my guitars to be exact), pickup height adjustment and individual pole screw adjustment (lowering it). Problem didn't get solved with this. Actually all of my guitars excibit this same thing with this patch and settings etc. (the guitars don't have any fret buzz or intonation problems, everything works perfectly, just took them back from my luthier)
I played with the low cut / hi cut to no avail (kind of expecting that).
Tried to tweak basic settings on the drive sim and amp sim (to no avail again).
Then I went to the advanced settings and started tweaking some params.
It seems that the problem goes away when I tweak (one or both of) these advanced settings:
a) Lower the supply sag to about 1
b) Change the Voltage from 60Hz to 30Hz or lower.
It's really strange, as I can hear the "ghost" note changing pitch as I change the Voltage value from 60 to 30Hz with every step of 5hz changing the pitch of the sound...
I finally ended up lowering the sag to about 1 and upping the level at the drive sim to restore some hair I had lost because of the lower sag value.
This seems to have fixed the problem, but I was wondering if this is some kind of bug or if it is normal, so I decided to post it, just in case someone else might be having the same problem.
Now, I can't upload the patch, but I can tell you how it is set up so that you guys can check it out.
I just used the plexi trebble patch, replaced the amp with the JTM 45 model, bass at 12 o'clock, trebble and middle cranked (bright on), presence at around 1 o'clock, master at 9-10, drive at 5.8, modern voicing.
For the drive, I used the fat rat with drive at 10-11 o'clock, level at about 3 o'clock (with the supply sag at 4.8 that is, with the supply sag at 1 I had to almost crank this), tone at 1-2 o'clock and at the eq page of the drive sim, I set the mid freq to 500Hz and pushed it all the way (I think all the way, I can't check now since I'm nowhere near the axe).
For the cab block I used the default that came with the patch (I think stereo green tv mix?).
I also use in my patch 2 mono tape delays in series after the amp and a reverb block. Of course the problem was there with the effects both on and bypassed (meaning it was still there with just using the drive/amp/cab blocks).
Anyway, lowering the sag, fixed it for me, although I don't get exactly the sound I was looking for (the one I really liked would be with the supply sag set to default values which was sth like 4.8 IIRC).
Sorry, I can't upload patches (my axe is nowhere near a computer), but if anyone's interested, please try the above settings and check it out.
I listen through a pair of Yamaha HS80M.
Guitars being used (all excibiting the same behaviour):
Epiphone les paul tribute + with Gibson classic 57's pafs
Warmoth custom made superstrat with Bareknuckle VHII pafs
Yamaha custom reconstructed 1212s superstrat with SD mini 59 and Bareknuckle VHII
I don't have the same problem in any other patch as far as I can tell.
Thanks in advance guys, have a good one...
