To Punch-In, you only need to hit the RECORD button to immediately Punch-In from an armed track in the Play mode to the Record mode. Then to Punch-Out you just hit the PLAY button.

You no longer have to hold down the PLAY & RECORD button to initiate a Punch-In . This makes your punches faster, more accurate and much more efficient with much less possibility of making a mistake by not hitting both Play & Record buttons simultaneously.

We construct a smal 'Fast-Punch' PCB board that attaches to your Logic Board that is hard-wired onto specific components on the logic board.

We then fully test your Fast Punch Board and burn it in inside our hot-room for 24 hours prior to shipping to you.

To order this modification, please place your order online from this page (scroll down). Then carefully remove your Logic Board from your M79 recorder (turn the power off first). And following the shipping details below.

Carefully wrap up your Logic Board in several layers of bubble wrap and place it in a sturdy shipping box, filled with additional packing peanuts and seal it up.

Then place this sealed box within ANOTHER outer shipping box with packing peanuts. This is the ONLY way to safely ship these boards to us!

Remember, these boards are priceless! Sapre replacement boards are very, very hard to find, if at all !
