I have just played it a bit.
In full mode. (my switch is broken so I can't use the split or parralel mode
) Think of a TZ. Think of all the bad points and get rid of them!! I love it for rhythm it has great snap and snarl!! I don't particularly like it for lead though it seems to be missing in the higher mids and treble to make a good lead sound.
Unlike its TZ cousin this is suprinzingly less bassy even though dimarzio say there is a small difference. I normally find the TZ muddy but in this case it is not, the bass has character and is not overly flabby. The treble is quite weak. It is just enough for crushing rhythm parts (particularly Megadeth) but has too little to do those 'widdley' bits!! I am going to try losing the tone knob to see if it brings it up a notch but it will have to be a BIG difference. The mid range on this is huge it isn't the vocal like sound you get from Freds/Nortons though. It isn't very complex either, its just basic mids!!! I assume this must be a non-dual resonance pickup because of it. Also its not like the mids you get out of an amp it is very fluid and has immense clarity.
Output wise the site says 330mV but it seems to be slightly higher than that I haven't measured it though. It is a little hard to do pinches on (but I am used to EMGs) I can't remember if it has an Alnico or ceramic magnet??? I am pretty sure its ceramic. If it is Alnico I might change it to ceramic for a bit more treble.
All in all it is a great pickup through my Marshall (DSL) it makes those lovely Van Halen sound (it seems to be more similar to the OEM Peaveys and MMs than the TZ as well!!) especailly for the Fair Warning era sound. Also I have got some pleasing Santana/Al Di Meola sounds out of it too. IMO this is great pickup for those powerchord riffs and basic all round rock rhythm but it lacks scream for solos, I would take this over a TZ anyday of the week it also puts my EMGs to shame. I think I am going to sell them now!!! I will probably end up getting a Norton/Paf style pickup next for the bridge. This pickup is great but isnot 'the one' for me.
