What's in the kit?

Absolutely everything!

  • Microphone shell, shockmount, cable,
  • Capsule,
  • Passive components (resistors, capacitors),
  • Cinemag transformer
  • Active components (tube, transistors, LED, ...),
  • Electromechanical elements (switches, knobs),
  • Connectors, relays,
  • PCB's,
  • PSU case,
  • All hardware

You bring the solder (use good quality solder, 1mm diameter max).


Difficulty level

The SK49 kit is not a difficult build but it requires a lot of care because some parts (capsule) are really fragile. In addition, the very high impedance circuit requires specific treatments such as cleaning the PCB with isopropyl alcohol.

A great microphone

During the last weeks I used the SK49 on a lot of vocal sessions, female and male.The results are stunning.This convinced me to get another one as a stereo pair on instruments, (chamber) orchestra, choir etc.Again absolutely great sounding.The capsule is fantastic,usefull in a lot of situations.
Has a lot of of polar patterns "in between" the standards which makes it even more universal (9 in complete!) - plus hpf if you want.A very warm sounding though not too coloured,clean,wide open and really full range microphone!
Everything I have heard from it while recording with "clean" gear like Millennia Preamps etc.was spot-on.When used with a more colored amp like 1073s etc it can easily convert itself into a soundmonster.....if you're after that...? Gorgeous!

The build quality is excellent, everything is included down to the very last nut and bolt.
The instructions are very clear and easy to follow.Just be patient and keep your workbench clean.
Once done you will have a marvelous microphone that stacks up to the "big ones" with ease!

A big thank you and my deepest respect to the people at Sound Skulptor!

Chapeau!

P.S.:Did I mention that it looks absolutely killer?
