This is keyboard #3 for me. I think I am finally there. Good feel with the Glorious Pandas (pre-lubed), good sound with a custom internal pad (poly-fill layers wrapped in tape and cut to size). Matching green metal knob from lovemyswitches (turns out knobs from guitar effects pedals fit well and come in a huge variety).
Anyway, I think I am done. My attention has been shifted to classic typewriters. I recently fell in love with the early 1970's Galaxie Twelve in Atomic Blue. (look it up, you too will be smitten). Now THAT is a mechanical keyboard!
I'll have to check out the effects pedal knobs! I have an actual guitar knob on mine, but I had to sand down the underside a bit to get it to have enough clearance to click easily. I'll have to check out effects pedal knobs!
