5 from 5 Neat build, true sound

Great easy to build kit. Sound is true to original, wall of chainsaw..
Beware that Ge diodes are glass cased and very fragile!

4 from 5 Great sound, but needs improvements

I ordered this kit a few days ago.
Building was very easy, the PCB has a very good quality.
After comparing the original HM-2 schematic with this one, I detected a few flaws:
- the 10p feedback capacitors need to be 100p
- the tone pots need to be 10k lin, otherwise the tone controls have no effect between 0 and 8
- one filter caps have a higher rate originally (C19 / 100µ), although this is neglectible
- a feedback capacitor is missing (C21 / 470p bridging R22 / 3k3)
- a filter capacitor is missing (C22 / 47µ connected from the node where R30, R8, R12 and R13 are connected to the ground), although this is neglectible

5 from 5 Sounds almost like the real thing!

This build was a bit more complicated than what I was used to, but I didnt have any trouble with it.

Sounds really good! I compared it to my original HM2, and the sounds are pretty close. You would not be able to tell the difference in a live setting.

5 from 5 Great Buzzsaw wall of sound

Since I discovered what kind of nasty pedal those guys were using to achieve those walls of distortion, I wanted it.
But really, the original ones are way too expensive in the used market so when this kit came up I was looking forward to put my hands on it.

The build has been nice and smooth,and the sound is what I was looking for, Im not sure the frequency response is completely faithful to the original, but I dont have an original one to compare it. Anyway I dont care too much, I can still manage to get the sound by tweaking the amp settings
