The other day I was posting in a thread about a DPA mic and a art preamp for double bass amplification. So, it has inspired me so mess around with a mic. I have had a audix m1290 miniture condenser mic, for 4 years and never used it ever, well except for testing, and I have an old art studio mp mic pre.
So here is what it looks like on the bass:
I quick and dirty used a nylon screw through a tailpiece hole with 2 rubber bushings on either side of the tailpiece to isolate it from vibrations and to keep the weight down as low as possible. I then recorded it using audacity on my mac (sorry about the poor fade at the end) Here is the recording:
The bass it an eastman 305.
Notes on 1st try:
I kind of like it. It has this pipe-organish sound. I have no idea how this would work on stage with a loud band and all, but I was playing through a small playback system in the live room and I had it pretty loud and no feed back. I know that isn’t a stage. I do suspect a low-pass filter would be essential for stage at the bare minimum, but neat.
Now, Second try:
I tried moving the mic closer to the top to extend the bass response. No workikie. When I get the mic close to the top, it gets really honky sounding. This is a supercardioid mic, so maybe that is why but it doesn’t make sense to me. If I lay the mic right next to the top, the bass doesn’t come up at all. Usually when you set a mic near a source, take it off-axis, proximity effect takes place. Not so with this mic. Neither “on” nor “off-axis” brought up the bass up close. I am actually baffled but I do know it takes some distance for low frequencies to come together. I’ve had this mic for probably 4 years and this is the first I have used it.
I did another recording. I altered the mic placement slightly. I moved it to the opposite side of the tailpiece and it now points to the inside back corner of the bass bridge leg. Definitely better as far as bass goes.
Pretty cool. And here I was looking for all sorts of pickups for the bass over the past couple of days and here I had something sitting dormant that I have never used. How cool is that.
Would love to get some opinions of the sound. I have a feeling a little high-mid scoop would finish it off quite nicely.
