Feeding samick guitar signal and mp3 into guitar input of samick amplifier.?
Hi, My wife is an amateur musician she has a samick amp with two inputs mic, and guitar, we are trying to input a mix of sounds into the guitar input. I have tried a connection from the headphone socket of mp3 player, in a double adaptor config with guitar, this is not ideal, due to the unbalanced signals, and there is a loud hum. What can I do short of buying another amp. Also I don't know what the impedances are but suspect the mp3 player is 8-16, and the amp input much higher.
I am wondering whether a simple mixer might help, but I don't know how impedance might affect this, or whether it would actually work.
Thanks for any comment
