Spoke to the supplier who thinks it was wired wrong, sent me a wiring diagram which I sent to the tech that fitted it and he followed the diagram and the mid control now cuts and boosts but still no mid sweep, the tech thinks the preamp is faulty, after not being pleased with the stock preamp and now this I am thinking of taking out the preamp entirely
I'm not going to tell you how much money to spend, but I think anything by EMG, Bartolini, Aguilar, John East, etc are all going to be worlds better than the Artec. At least with those brands you will receive some actual support direct from the company should something not be perfect.
I'm not sure which country you are from, so availability and price may vary. Here's some options -
Invalid Link Removed - mid sweep, compact, easy to install
John East UNI-Pre 4 knob - fantastic preamp with a lot of configurable tone options, active/passive, mid sweep, easy to install with minimal soldering
Bartolini 4 knob preamps - mid selector, no mid sweep
Aguilar OBP-3 - mid selector, no mid sweep
Nordstrand 3 band preamps - several options, but mid selector and no mid sweep
