Ampeg Geminis (at least I & II) have bright switches built into the treble pots to engage a bright cap and a switch on the trem speed pot to engage a trem "afterbeat" mode. The problem is, the switches only engage at the end of the pot's travel. So if you want the bright cap engaged, the treble must be all the way up, and same with the trem speed. If I replaced those pots with a pull switch type and wired it up the same way, would it work? It would be nice to have the bright switch engaged without the treble all the way up. I'm not sure how it would work for the trem, but maybe I could get the afterbeat effect at a slower rate?
