Nice to hear from you. I hope all is well. No, I used a standard mono speaker jack to make it foot switchable. Thanx for the info. I wouldn't know how to install the LDR. I replaced them in my 2:90 but that was for the half drive mode. Which didnt help with the pops. Anyway, i'm not sure what to do at this time. Its been groovy without the mod activated. I started with a 2.2 uf T110. I think that I already asked you but do i need to put the 100k in? or is that just for 10 to 15uf's? Or , even w/ the 2.2uf in, will it thicken up the gain? Thanx for your time, Jim
