hey everyone. i'm thinking of building my own preamp. i've built/modified a bunch of effects from old stompboxes with some interesting results and since i've got nothing more lying around broken i figured it'd be time to maybe try my hand at building my own preamp for vocal purposes and maybe some drum recording. now i still consider myself a beginner when it comes to soldering and wiring since i've only got 3 years or so of time under my belt (compared to some of the people on here that certainly makes me a beginner) and i'm looking to see if someone could recommend a good starting off point, like maybe a site with schematics that they know are good and complete or a good place to order parts from. i'd prefer if someone who has built their own preamp could recommend how to approach this sort of project. thanks a lot!
I know a guy that can make the assembly work for me. So i am also thinking wich piece of gear should be easy enough to start with but good enough for the effort. I would love a LA2a or a neve pre. What should be the best easy Vs. interesting gear to build first?
I just built 2ch of api312 clone without a scope, and they sound wonderful. No problems whatsoever.
Im just curious, am i missing something important here? In regards to tweaking the circuit etc?
btw, i can highly recommend api 312 as a good starter project. Very easy to get right, and not hard to find parts for.
the last pre i built (never made it past a very loose prototype) had all sorts of oscillations going on. actually, the thing would sound drastically different each time i powered it on. after trying various filter circuits, i finally drove ~50 miles to a friend's shop w/ a scope, and found all sorts of oscillations going on... and they would change with mic plugged in, open, phantom applied, phase of the moon, etc. etc. etc. i tried swapping opamps & the like, finally got something sort of working, but it didn't sound good, so i ditched it.
the api clone sounds interesting. wanna send me a schematic?
