I noticed the same thing as well; long left/right presses on the empeg (or the remote) don't initiate a freq. search.

Also, I've tried (via presets) BBC - Radio Berks / Radio Oxford / R1 / R2 and nothing on the AF debug display so far (but I've not stayed in tuner mode long enough to _really_ say something's broken there).

FWIW, one thing I did observe is that after a long press (in tuner mode, i.e. freq. search) the empeg is momentarily busy after the button is released, perhaps for about 0.5 seconds.
