This ckt is good. If you want to be able to adjust Vpp, use a
little potentiometer instead of the diodes, a .5-1K pot should
fine work with the 3K resistor shown.

Less safe would be to replace both 3K and diodes with a 5K pot
[less safe in that it is more easy to fry something in case where
the pot is adjusted to the wrong position].
