Tired of not being able to find those J201s or 2N5457s? Or worse: worrying that they're fake? Convert MMBFJ201s and MMBF5457s easily to use in standard through-hole setups with this. You can also choose whether or not you want me to solder the transistor for you. Comes in packs of 4.
This little bad boy now has everything as the original Effects Tester, and also includes an audio probe, charge pump (-9V and 18V), and frequency generator. It makes finding those irritating issues with your circuit a breeze!
