Spark Amp App Tuner
-
I struggle with the Spark Amp tuner because it does not tell you which note you are tuning to. The Yamaha THR-10 has a similar tuner, but it also has a display which shows which note you are tuned to.
Obviously we can't add a display to the Spark, but maybe you can add a tuner to the Spark Amp App which can show the tuning from the amp with the note you are tuned to.
