salut mec, moi chui a rimouski (bas st-laurent) et le mien il as une "poff" de bass vraiment trop basse et presente, je peu quasiment pas utiliser de humbucker avec, par contre avec des singles coils c'est jouissif

est ce que tu as testé tout tes voltages, fais des modifs ?
parce que une solution assez simple serais de reduire la valeur du pot de treble ou encore augmenter la resistance du grid stopper(input)

au pire envoie moi un message et on pourras sechanger nos coordonnées pour pouvoir tweaker ca, moi j'prendrais bien un peu plus de high :twisted:

btw, sorry for those who dont understand french, im just tryin to help a fellow 18watter :wink:

no offence to anyone here !

No offence .. Thanks for helping. We all want to help.

To Fatten Tone on sIII Channel
1. Change C1 to 0.022uF
2. Change C2 to 2.2uF -OR- change R5 to 2.7K -OR- both
3. Change R11 to 33K
4. Change VR5 to 500K-A or 250K-A to give the bass control more useful range

For modified Treble control, try the following modification to the R-C filter around the Treble control potentiometer.

33K /250pf– more gain and treble;
47K/330pf - middle of the road;
56K/500pf – bassier slope, less gain

You can try various combinations. Also, yoiur tbe for V2 may be harsh as well, try a different one perhaps.

I would also check that the values you have in there match the layout and the tube is good. It's rare for someone to say the TMB channel is too bright.

That's the first one I would try. Even 0.01uF or 0.015uF might be enough.

Also, what kind of speakers are you using? They have a huge effect on tone.

G12H-30s are great speakers for Marshall 18W style amplifiers.
