I think this pedal is great and sounds very good.
I have built a Laney Supergroup pedal and also a Naga Viper.
If I put the Naga Viper before the Laney Supergroup, then I get very close sounding like the Sabbra Cadabra.

Hello Mboratto!
Yes I coverted the Laney Supergroup Amp from tubes to JFETs and the sound is very close to the real thing.
I will see if I have the layout somewhere, or you can search on the Web for laney supergroup amp and the Catalinbread Naga Viper.

I haven't found the layout yet, but here is the schematics of the amp.

Heloo Mboratto!
I used the same values, but not R14 and the capacitor on the power line, I used a 100uF.
I replaced the resistors to the plates of the tubes with variable resistors, this is for that you can adjust the voltage of the drains of the transistors, start to adjust the voltage with the half of the power supply voltage (approx. 4.5V), and then adjust after how you want the circuit to sound.
For the power supply, I used a 9V battery, you can also use a charge pump to get 18V for more headroom, but then you have to adjust the variable resistors again.
Hope that you will get this pedal sounding good.

imho looks like first stage
from RunOffGroove "FET treble booster similar to the well-known Dallas Rangemaster", that has Range pot with similar effectA custom-tuned Rangemaster-based booster combined with the pre-amp section of a Laney Supergroup

Best pictures ever but i wouldn't have expected anything less . R30 needs 1M on it
