I will try to bring the overtone preamp cathode resistors (cl1,cl2,od1 and od2) from 3.3k to 1.5k, as reported on the #124 schematic...also the caps on cl1 and cl2 will be replaced by 10uF...
I expect a bassier sound and more clipping in the lowend portion...am I wrong? Do you think it's a good idea to apply at the overtone layout?
#124 cathode resistors and bypass caps...

Re: #124 cathode resistors and bypass caps...
That will only work if you make corresponding changes to the plate resistors (i.e. 100K across the board).
Try it if you want, but I think the general concensus is that the OD sound is smoother with the higher plate values like the overtone, or even 220/150/220/150. At least that's been my (limited) experience. I tried #124 preamp values and although the clean side was quite a gem, the OD was less satisfying. I ended up yanking the low plates in favor of high plates to smooth out the OD. YMMV.

Re: #124 cathode resistors and bypass caps...
Thanks for the advice...So if you're a clean player, ala Mayer, better to go with 100k/1.5k/10uF...
I'm still not completely satisfied by the OD tone, so I think that this direction is the wrong one to take...

Less satisfying in a living room, more satisfying with a band

Funk - Do you honestly feel the OD of a low plate non-HRM sounds better than a high plate in the band setting?
