I installed the mic on a Rickenbacker 4000, 1971, replacing the microphone that I was sold with the low (4781st hand apparently). The microphone does not seem original because the black plate which is fixed on the microphone had been planed to go into the pit. In addition to the microphone and Larsen squeak to death, a horror. In fact my 4000 was (badly) altered in 4001 with the addition of a micro bridge, the body was dug up for placing the microphone neck. The wiring was catastrophic and the knobs were unusable. So I turned everything, replaced the microwave bridge and removed the microphone to make his neck look original to the machine, changed the pickguard, and most importantly, I expanded the pit to the router to be able to slide the microphone that not return. As the wiring diagram is for a 4001, I suffered a bit to find my way but I got ... yet I am far from being an electronics engineer. I shut it off, I plugée a Gallien-Krueger MB150 combo and ...
Miracle. The sound is punchy, roots, precise, bold and chattering, buzzing like an old Harley assembled piece by piece. I ran to the rehearsal the plug on my rig Ashdown EVO 500 4 * 10 1 * 15. The musicians in my group of stoner are almost cried. At the mediator is perfect for the big sound that kills. In the genre, it's impossible to do better after the amp is taking over. And it's passive!
So, as a replacement microphone for Rick's big rock'n'roll severely burn, it's unbelievable. I will not go further to be able to resurrect this bass and have an unparalleled power. Yep, thank you Seymour.
