My Street Rod has lost the edge in sound. No problems volume only lack of harmonics.
Changed all the tubes remains the same. It seems preamp problem.
I do not get scheme. It is possible to get. Scott does not answer my mail.
Excuse my English. I am from Spain.
Thank you.

Try resenting your email...sometimes when I email him he doesn't get back to me until I resend it.
In the meantime check all your cables, make sure your bias is set correctly at about 65% of plate current. And if you have preamp tubes already it can't hurt to try and swap them one at a time and see what happens. Check your phase inverter tube also.

^I think he is looking for the electrical schematic because someone told him to get it. To mod it topox? I'd be really surprised if that is the problem/solution. Scott doesn't post his schematics for reason. I personally do not think it will do you any good. Don't spend money on a tech until you do some basic things. make sure your bias is set correctly at about 65% of plate current. And if you have preamp tubes already it can't hurt to try and swap them one at a time and see what happens. Check your phase inverter tube also. +1 This is what I would focus on too. A cold bias will def make your harmonics and girth disappear. Plug your guitar directly into your amp. What tubes do you have in there now exactly TS? |
