5 from 5 Simple & Nice kit

Only few parts, it requires about an hour to be fully operational.
Sounds extremely good, directly on the input stage of the ampli (where at higher volume setting, it can be used as an overdrive) or either in the sendreturn chain, where its an incredible booster.
I cant tell if its comparable to the original effect, but its a very good, easy to build kit!!!

5 from 5 Makes the difference

Have plugged it into 5W, 15W, 30W, 60W & 100W amps of several brands. A/B-ed it with quite a few other boosters and it remains my favorite. I did reduce the controls (a para and a series resistor) by 50%, to tame it a bit and be able to (easier) finetune its boost. Its currently the last pedal in chain to go into my JTM45 to give it that extra little push from time to time (90%) and it aint going nowhere. Makes your playing style and dynamics come out far better. Always makes the audience go wow and check out the little box...

5 from 5 Amazing

So easy to build, so wonderful to play.
It took my sound to a new life, cutting into the mix without raise the amp volume.
I put it into a single enclosure together with a DerScreamer, also from Musikding, and they are both great. Their combination is simply all I need to play whatever I play...

Highly recommended.

5 from 5 Good boost

Very good kit, nice PCB and quality components. Easy to built with schem (dontt forget to download...) and let place in a 125B to have a buffer or else.
Thanks musikding !

5 from 5 More than a boost

Its really an impressive pedal. Just one knob and a lot of possibilities. Kind of preamp pedal. Sounds really great.

5 from 5 Warm boost

Really bridges clean to overdrive with something warm and furry in between. More than just a volume boost if that is what you are seeking. Buts its nice! And an easy project to start your stomp box empire!
