Epiphone G-400 and Roland Cube 30 Creating 'Shadow' Notes on Some Settings
I am really enjoying my new Epiphone G-400.
However, after having played around with it since getting it 4 days ago, there is one thing about it that I have noticed that I would liketo get your opinions on, and which I am slightly worried about.
When I plug the guitar into my Roland Cube-30 , combo and I play the 2 notes of what I assume is a major 3rd, on the 1st and 2ndstrings of the G-400 (e.g. an E note at the 5th fret of the B string and G noteat the 3rd fret of the E – 1st. String), I get a kind of 'sympathetic' or 'shadow' note sounding in addition to the 2 notes of the major 3rd..
This effect occurs when I play a major 3rd at any point on the 1st and 2nd strings, and as I move the frets at which I play the interval, the 'shadow' note changes in a logical fashion.
For example, when I play a D note on the 10th fret of the 1st string, combined with a B note on the 12th fret of the 2nd string, this causes a G note to be produced (it is exactly the same as the note at the 3rd fret of the 6th string). If I slide the interval down a fret, so that I am playing the 9th fret on the 1st string and the 11th fret on the 2nd string, I get an F# note, as if I am fretting the F# at the 2nd fret of the 6th string. If I move the combination up one fret, it is as if I am playing a G# at the 4th fret of the 6th string, and so on.
This 'shadow' effect does not occur on the amp's 'clean' channel, and similarly it also does not occur on the first and second of the amps 7 settings on the gain channel (the 'Acoustic', and 'Black face' emulations).
But, unfortunately, one can hear this effect in the following emulations: 'Brit Combo' 'Tweed', 'Stack Classic', 'Metal', and 'R-Fier'. That would be good news if I did not use any of these emulations, but of course I noticed that this happens because I use the 'Brit Combo' 'Tweed',and 'Stack Classic' all the time.
This effect also does not occur if I try any other kind of interval – only with the major 3rd..
The effect occurs on all 3 of the pick-up selection options.
Has anyone experienced this phenomenon before? If so, is there anything that I can do to get rid of it?
At first I thought that maybe one of the guitar strings wastouching the fingerboard or a fret or something, but that is not the case. I also tried palm-muting the strings that I was not playing, but that does not help, either. And I am quite confident that the speaker is fixed securely within the amp's cabinet, i.e., that it is not loose and moving back and forth.
Maybe this is purely a drawback of the amplifier emulations,or maybe, for some reason, it is what happens when you use this particular guitar with these settings on this particular amp. It is interesting that this happens with the emulations on the amp which are affected by gain – one cannot overdrive the 'Acoustic' and 'Black Face' emulations, even though they are on the gain 'channel'.
I would very much appreciate your opinions, and help withthis.
All the best,
