Title: Golden Oldie, The EA TREMOLO
Post by: darrenw6000 on March 14, 2017, 07:49:31 PM
I went back and built the Tonepad EA Trem the other day, all working just that the RATE (B100K) is reversed so clockwise the rate is slower. I can't see why it would be, anyone point me in the right direction to get the rate better, i would have thought a C100k might have worked but it didn't.

Would swapping your wires to lug 1 & 3 of the pot do the trick? 

A 'C' pot would change the taper, so it would change your speed more quickly at one end of the rotation than the other.  If you want to completely reverse the effect, I think just swapping lug 1 & 3 will do that.

ya i think this is the answer, swap lugs 1 & 3. an B or C taper will both work (or even A taper though the control will be really bad). the C taper should give the best control over the lfo speed.
