Too much attenuation changes the tone and makes it sound boxy. Be sure to use the correct value power (wire-wound) resistors for output impedance and using resistors with a high enough power rating is important but with the low wattage amp like the 2Stroke that won’t be much of an issue. 15watt resistors would do for amps up to 25w according to Gerald Weber’s book. I reviewed my copy and found that construction of both the single stage and two stage versions of his attenuator are featured.
