Looking to replace the preamp as the bass boost thingy just makes tone muddy. I was a Spectorphile pre-Korg, so pretty sure I want EMG. I replaced the stock bridge with an entry level Babicz bridge (awesome!), but prefer to leave the electronics to a tech (surprised I didn't break out in hives changing the bridge! Me and tools usually don't get along well). This whole mod thing is somewhat new to me. But I DO know it's passive. Any insights you fine folks here on the forum can give me would be appreciated. P.S. 1st choice; all EMG. 2nd choice, all Seymour Duncan. Thanks so much!
