Hi Mike and everyone, I went to the factory again recently to sort out the design for a true bypass footswitch circuit so it can have an LED on/off indicator. That is working well so now Stephen is arranging the next prototype board layout which I am looking forward to seeing. Because there will be a true bypass it will not be possible to have a balanced output connection. Not a great loss, it would have been easy enough to do if there would have been an output stage in use all the time but I thought a true bypass would be a better idea.
Hi Glen, Thank you. I have added you to the list.
Hi Mick, I did in fact already put you on the list, rightly or wrongly!
Hi reverbrob, Thank you, I have done that. Please note that this unit does not contain an EF86 valve, it has solid state circuitry that emulates 2 different EF86 circuits from the AC15 models of 1959 and 1960. Regards, Charlie
