Skjold Tone Audio (STA) preamp. Purchased and installed but I recently put bass back to passive.
Specs:
Volume - Active/Passive Push/Pull
Blend
Passive tone control
Dual Mid - Boost/Cut Push (low mid)/Pull (high mid)
Stacked treble/bass Active tone control
Works as it should. Comes with metal knobs. See photos.
PP. Shipping CONUS included.
