It could be much better

After 4 builds from this site, Im sad to report I didnt like this kit. The sound is fine, but its just not a nice experience. I was expecting an easy straight forward assembly and a solid pedal, but odd technical decisions makes this a pedal that I wish it was better, but its not.

TL;DR:
PRO: Good sound
CONS: fragile build, small solder connection, odd LED functionality, wrong documentation.

The board is 100% secured in place by the LED, which made it very fragile and I had to re-do the LED connections because the first time it broke, other kits uses the potentiometer connections to hold the board firmly. So I had to add insulation internally in the case to make sure nothing is shorting. And the LED holder is not the nice quality aluminum holders from other kits, its just a flimsy plastic one. If I was going to start it again, I would put wires connecting to the LED to the board to avoid breakage.

Talking about wires, such a small build, so many wires. wow.

The board itself has very small soldering area for each component which are difficult to solder and creates funny looking solder points which dont seem too robust and I wouldnt trust for a tour.

The LED design is odd at best. Its a 2 tone LED (green/red) for a 2 switch pedal, great, so we get off-> off; 1st boost -> green and 2nd boost -> red, right? Wrong! It is off -> green; on -> red. If its the 1st or 2nd boost on you just have to hear and try to figure out by yourself.

The documentation was also wrong regarding the 2nd boost potentiometer, the cables were inverted and was full boost at 0 and no boost as max. I had to swap them around. The documentation is also very vague regarding the bass boost; which is another odd choice to add to a transparent boost.

The redeeming quality is that it actually sound pretty nice, I could see using this for recording (where foot-click accuracy is not so important and it wouldnt be throw around like in a tour). I can get a crunchy Black Sabbath on the 1st boost on my British sounding valve amp, and a full-on distortion with the 2nd boost. All by just boosting the volume.

But said all that, I just ordered the HardOne boost and you can check the review in a month or so.
