Can anyone help with advice on tuning guitar when trying to record a solo over a jam track? I tuned my guitar to concert pitch and used a Circle of Fourths Jam track by Griff. No matter how I tried to tweak the tuning, the final recording still sounded out of tune. Okay, so it was a basic way of doing things via my smartphone with the guitar plugged into computer via Multitrack Mix with the Jam track playing from a computer file so quality was never going to be good. I would like to know why it didn't sound in tune. Does anyone have an answer please?
