Hello...
I´ve a difficult question... is there any way to increase the Output of a Tubescreamer... is possible?
There is a formula to achive that?
thanks, all the best
Simplest way (and common) is add a booster after it. It is also possible to change the R in the feedback loop of the second opamp stage, but this also changes the tone response, it gets shrill.
People who don't know what they are talking about have active imaginations try running them on 18v. Unlikely to have any good effect without changing the second gain stage (and compensating by altering the tone control.)
BYOC OD2 is a tubescreamer with mods and an added booster.
Replace one of the feedback diodes with two diodes in series (as in Boss SD-1) or a single LED.
Jim's suggestion WILL increase output, but the clipping will be different. Perhaps a better approach is to raise the gain of the tone-control stage. Stock, it uses a 1k feedback resistor. Increasing that to 4K7 will raise gain and output substantially. The problem is that it will also change the functioning of the Tone control at the treble end (but not at the bass end). Using 2K2, instead of 4K7, will also raise the gain of that stage, but with a bit less impact on the Tone control functioning.
