I have a couple of those wildly popular and super inexpensive Chinese-made condenser microphones for home recording. They're wonderful for the price, but they tend to sound 'unrefined' and bright. Of course, they do cost 1/20th what a Neumann costs, so you get what you pay for.
Enter Microphone-Parts.com. These folks make a variety of upgrade and mod kits and capsules for the aforementioned microphones to dramatically improve them. I took the plunge, and am upgrading an MXL 990. I bought the 990 used online for a paltry $36! (About €33).
The parts are excellent quality (Dale resistors, Wima caps) and the PCB is first-rate. The instructions are extremely clear.
Aven circuit board holder/stand. I don't do a lot of PCBs, but when I do, I struggle with working on them.
No longer. This thing is GOLD! It would be a bargain at twice the price.
If you use an alligator (aka crocodile) clip to hold one lead while you solder the other, the component will remain tight to the board. You won't have to bend the leads and you'll have a much cleaner joint.
You gotta love that PCB holder. Where have you BEEN all my life?
No more chasing your roll of solder all over the bench. I have wider solder (for radios and amps) on the top, and thinner solder (for PCBs like this) on the bottom.
Another 'cheap and cheerful' device.
