Title: Treble booster minor differences but... how much minor?
Post by: rockaffe on April 20, 2025, 01:41:08 PM
Recently I've built a clone of the TB-83 treble booster. The schematic I've come up with (or better, the component values) is the one in the image.
It's sound great, no complaint at all.
But.
Some days ago, I've come up to a schematic of the same TB that have some differences in component values, and I would like to ask, how much those differences have impacts on the general behaviour of the effect in order to decide to build another one with those value.
Here are the "other" values:

R5: 120K
R4: 1K
R8: 2K4
R6: 47K

R5, R4 & R6 : Never mind the bollocks..
R8 : 11% lower Collector current..
