These boards are very versitle and very well made
I got these boards to experiment with. They are really well made, and (assuming a good soldering iron for circuit board soldering) can be un-soldered and re-soldered several times. Being able to easily vary component values and voltages in a design is SO simple using these boards. So far, I have installed one into a 5W Fender Champion 600 and another one into a 75W Fender Bandmaster Reverb with little or no issues. Five-stars!
