Did anybody find any major differences between the older (red )pickup booster SFX-01 and the new one (brown) ? The older one might start the db boost at minimum 6 db, the newer one i gather starts at 0.
The main difference I can tell is that the old version had a 470k input impedance and the new one is 250k. The 1st one is easily modded, (with one resistor), to be 1M input impedance with the gain starting at zero.
