Just received the new Palmer PDI -03 JB last week. Compared to the classic 19" PDI -03 unit, I like the new one better, even without having to engage the JB mid boost options switch. The "normal" setting is now warmer and much more usable than it is on the classic version, where I always wished for a sound in between the "mellow" and "normal" settings. Normal was too treble and mellow way too warm. The "deep" option, while still adding a convincing 4x12cab low end punch, sounds less boomy and is much more usable than on the classic unit I have. The two "JB" settings really bring out the mids and make the signal for PA or studio recording much more usable without the need of using any or hardly any additional EQ. The signal and sound are simply "perfect" IMHO. Compared to the Mesa Cab Clone, the new Palmer beats it by hands down in terms of speaker simulated sound, and the Cab Clone is a very good solution to begin with already. Of course it does not provide a resistive load like the old Palmer PDI-03 or the Cab Clone, but I don't care for these loads anyways. They sound so dull and are lacking all the dynamics that a real speaker or a properly designed resistive load provides. While I am using Ownhammer IRs for recording in my DAW, for live use I can't think of a better sounding solution. It is better than the Torpedo Live, even when loaded with Ownhammer Mix IRs. The sound is more direct and it sounds so natural, big and fat but also providing the necessary midrange boost to cut through a mix. Absolutely stellar sounding and working unit.
