A) Boost:
I built a simple duende boost from the tagboard FX site into the shell of an old chorus pedal I wasn't using. I also built this on veroboard so I'm amazed it works, even though I managed to break the mains adapter. It's batteries only until I make another parts order.
Soundwise I really like it and I find myself leaving it on to give my amp a little kick.
B) Tone mod
The Fender Excelsior comes with a tone switch instead of a pot which is neat in some ways but curseworthy in others. fortunately replacing the switch with a 500k pot is well documented online and easy to do, even with my clumsy hands
It seems to work fine, and its good for taming the high end a bit. The hardest part about this mod was adapting the switch space as well as the washer I used to fit the pot. I did have a 'oh fuck I've bricked it' moment when I first fired it up; seems like when moving the amp around I must have just nudged the fuse out slightly.
