After my modding of the BOSS SD-1, he got the idea that we could mod his Blues Jr. I have to say I was hesitant. I am a novice at soldering and the SD-1 mod was my most advanced project by far. Lets just say he had more faith in my skills than I did. So he bought several mods from billmaudio.com .
He bought the following
- Standby switch - very easy and one I have ordered for my own Jr
- TwinStack mod - free mod
- Presence control - hard one
- Sparkle control - another hard one
- Basic kit for the cream board - inexpensive but a lot of work
It took us about 4 hours to complete these and we left off the bias pot because it was getting late. Another day.
It came out great! I have to say I was really impressed with the results. I did purchase an expensive soldering station with digital temp. I didn't want to screw this up with my old soldering station. That thing gets way to hot. The new station has a really fine tip as well. Making fine work really easy.
Here is the top with new jack, standby switch, presence, and sparkle controls:
