OK, I own a Shure FP-24 the same as the mixpre, however it does not work on rechargables. Shure will not mod it and I am told Sound Devices will not either. does anyone know if there is a way to hack this to be done on one's own? I am in europe so shipping it to them even if they would fix it would be a proposition, and after my adventures with the mail here, no thanks.
