Hi - i have a Spyder three that I haven't used in a while, and i'm having an issue. When i plug in my acoustic, it doesn't have any sound through the amplifier.
Not sure if this matters, but i had lost my cables so i went out and bought a mono cable. This worked with the electric guitar, but not with the acoustic. When i dismantled the acoustic, i found that it actually has a stereo output, not mono.
I confirmed that the acoustic guitar has output, and if i use a stereo cable converter to 1/8" to plug into the "mp3 in" line, it works; however, if i plug into the instrument 1/4" plug, it doesn't work. As noted above, i confirmed by plugging in the electric guitar to the 1/4" input that the amp worked.
What am i missing here?
