I tested a pair of the LINTEC's in stereo on the drum bus and mixbus, I also tested it in mono with drums, guitars, vocals,...
Allround I think it's not bad for the price, but after comparing it to some other Pultec clones and the UAD Pultec plugin, I noticed I liked the LINTEC's the least. It has a nice round and solid low end in my opinion, but lacks some clarity in the highs, especially when compared to other clones. The rotary knobs work with increments of 1 step, you can't for example boost between 1 and 2, it's either 1 or 2 nothing in between for finetuning.
Overal, I liked the LINTECS. They are a good solid state Pultec style EQ if you want some extra attitude on your mixes, but I still prefer other Pultec style EQ's with tubes as they sound more faithful to the original.
