Thanks. The OEP30w appears to be an excellent choice. :tu:

Some advice that will help;
1/ The circuit you post is not the best design as it's a pedal not really intended as a dedicated preamp, unless you just want distortion all the time with no real tone control.
If you want a small battery powered amp then just build a simple preamp and add dirt circuits afterwards.
Just track down some easy small amp circuits,, try Vox pathfinder 10 comes with clean and dirt. :tu: The preamp will work from single supply with some modifications.

Also, I don't know how 1W resistors could give "better results".
Better how? Please define "better".
You only need higher watt resistors (1 watt and above) if the circuit demands require it.
Brush up on ohms law and calculate the current flowing in the circuit to determine if the higher wattage resistor is needed.
