TechDude New Member Jun 25, 2009 #21 Well if i use this preamp with the circuit you provided before it should work right?
audioguru Well-Known Member Most Helpful Member Jun 25, 2009 #22 We don't know what is the sensitivity of your obsolete ceramic mic. So we don't know how loud you need to scream at it. A FET preamp (used for a guitar) is a much simpler circuit and can have some gain.

TechDude New Member Jun 25, 2009 #23 So i could use this FET preamp and it would increase my decibels considerably?
audioguru Well-Known Member Most Helpful Member Jun 25, 2009 #24 A FET preamp has a max gain of about 20 which is 26 decibels. Here is a FET preamp with an adjustable gain control: Attachments guitar preamp with gain control.PNG 7.3 KB · Views: 1,123

TechDude New Member Jun 25, 2009 #25 I'll try this one. I'll tell you what happens. But there is only one wire leading to output... would I connect the other wire to the ground? Last edited: Jun 25, 2009
