Three band tube equaliser SEQ3 is the best choice for your recording and mastering studio. It is based on famous Pultec EQP-1, but it is just not a copy.
Input and output are galvanically isolated by our high-end trasformers, which are responsible for elimination of ground loops. If needed, ground can be connected to output XLR connector by a switch (like on NAT3 studio preamplifier).

LOW band has typical separated cut and boost controls so you can do typical "low-end" trick if you want. Low frequencies have fixed steps and they are chosen very reasonable.
We added MID band control and this is a big advantage if you want to suppress muddy and boxy frequencies or you want to bring some presence in vocals. For MID band only one cut/boost pot is used. MID band section can be fully bypassed!

On HI band we added peak/shelving selection, which is again a big advantage of our SEQ3.

SEQ3 is only in mono, for stereo (mastering reasons) you have to use two equalisers, which we can pair for best L, R symetry.
