This is the Klark Teknik EQP-KT. Real tube in the signal path. Custom-wound Midas transformers. Switchable frequencies and variable bandwidth, the full Pultec recipe from a company that's been building serious pro audio in England longer than most plugin developers have been alive. The internet has opinions about the affordable one. Run your mix bus through it and see if you still hold them.

Here's a secret the boutique guys would rather you didn't know: the Pultec trick doesn't care how much you paid for the faceplate. Boosting and cutting the same low frequency at once shouldn't work on paper, but it makes kick drums sound like weather, and it works the same at this price as it does at four grand.

What it actually does: low end gets bigger without getting muddy. Highs open up without turning brittle. You reach for the boost knob and suddenly everything sounds more expensive. It's the oldest move in the book because the book got it right the first time.

Condition is excellent. Clean faceplate, smooth pots, switches feel tight, works exactly like it should. Includes the original box and a quick start guide still sealed in plastic, which should tell you how much troubleshooting this thing required. Home studio use, low hours.

Stop A/B-ing emulations at 2 in the morning. The hardware costs less than your plugin subscription and it hums a little when it warms up, which is how you know it's alive. Ships in the original packaging.
