I have been thinking about adding an OB compressor to the rack recently, and, being on a budget I have come across the ART Pro VLA II. This thing seems to get a good wrap for the price, and general concensus in regards to feedback is they sound better when the standard stock chinese-made tubes are replaced with Mullard 12ax7 tubes. Iv'e heard it referred to as "the poor mans' LA-2A", which, would suit my budget. (its retail is around $800 bucks new here in OZ...(thanks shitty-dollar value due to the fall in commodity prices....) The question(s) I am asking would be the following :- a) - Has anyone who has had experience be willing to share their thoughts on this compressor? b) - In todays' world, where our choice of plug-in compressors are overwhelming and one is spoiled for choice, is it really a necessary purchase in regards to what plug-ins can do in comparison?? I would be looking to use it as an aux send as opposed to front loading the unit, primarily for vox use. I know ART stuff is entry level gear and most of it should probably be steered clear of, but would appreciate any thoughts / feedback.
