Question Is it possible to use the Ditto Looper to sustain a chord or a note indefinitely, like the EHX Freeze pedal Answer Yes and no. It is of course possible to create a very short loop which simply repeats a chord as long as the pedal is on, but you will be able to the strum each time the loop repeats. Also, adding overdubs will quite likely be rather tricky as the first loop determines the overall length of any overdubs.
