Built a new pedal with one of the GBOF boards I had laying around.  I wanted to build a modified Hornby Skewes Si Treble Booster with features I would incorporate into a commercial pedal if available.  Way cheaper than a BSM pedal, but more versatile.  I added a tone control consisting of a variable input capacitor (borrowed from another Si based treble booster schematic) as well as a “Thick” switch to change the standard output cap of 1n to a 10n output cap that just “thickens up” the sound to my ears.  Schematic and board layout below.

I also used 47u and 33u Capacitors in parallel for an 80u capacitor equivalent to keep true to the original schematic, but 100u works fine here and actually some vintage Si HS treble booster photos show 100u and 125u caps as well.  Finished pedal pictures below.  Unfortunately after the last clear coat dried I dropped the enclosure on the paver brick patio resulting in the damage to the right sided corners of the pedal, but I was just not going to start over again with the enclosure graphics and finish.
