5 from 5 a fine treble booster even the finest

very easy to patch. The sound is great. Actually the sound is very similar to the finest treble booster BM-Q from BSM. If you want a treble booster to get the same tone as Brian May this is your kit. Patch it and turn the volume completely.
You can also get some bluesy tone with the volume at 12. This treble booster is very versatile, especially with the guitar volume.

3 from 5 For beginners

The PCB is very easy to assemble.
Very recommended to all people with little experience.
The increase in volume is strong and the sound is very vintage, has a background noise that I do not like.
I made five other pedals, with a major construction difficulty and this is the only one with this defect.

In Italianl PCB è molto facile da montare.
Molto consigliato a tutte le persone con poca esperienza.
Lincremento di volume è forte e il sound è molto vintage, ha un rumore di fondo che non mi piace.
Ho realizzato altri cinque pedali, con una difficolta di costruzione maggiore e questo è lunico con questo difetto.

Per principianti

5 from 5 Good choice

Very easy to build if you follow the instructions. This was my first proyect, and worked just fine. The pedal gives a good amount of gain (about 30 db, I think), providing a nice chime when rolling back the vol. pot. on the guitar. At full volume it sounds massive, creamy. I mounted it into a B enclosure, adding the knob from the picture (6,3 mm shaft). Recommendable for any BM sound enthusiast.

5 from 5 Great pedal kit

Pretty simple and straightforward to assemble. It took me about 1 hour. It sounds pretty good. I tried it with a Fender Bassbreaker 15 in normal mode. As soon as you turn it on, you get this amazing sound, just like the early Black Sabbath records. The sustain is impressive. No need to use the overdrive channels on my Bassbraker anymore.

When I ordered this kit, I was not aware that it uses a Silicon transistor. Nevertheless, it is still terrific. I am now going to order The Range, which uses a Germanium transistor, and compare the two.
