Hello all. I have been unable to find back panels (used or repro) for MM 130 Reverb and MM 65 Reverb heads. I am working with Mojotone and they can make some. I need help with a couple of measurements. I created the template (attached) and sent to them. They came back with these questions that I need help with:
- depth of v-notch
- width of v-notch at bottom
- height of the parallelograms
- distance between the bottom of panel and bottom of parallelograms
Any help? This could be a great source for those needing back panels.
Estimated cost from MojoTone (as of Feb 26, 2020) is $50.

MM Head back panel help! need measurement
Soultrain65: For my HD130 Reverb, I measured 2 3/8" for the depth of the v-notch, 15.5" for the width of the v-notch at bottom, 2 3/8" for the height of the parallelograms, and 1 7/8" for the distance from the bottom of panel to bottom of parallelograms. And not to muddy the waters, but for disclosure, I took some other measurements which may differ from yours: 9" for the height of the panel; 1.5" from the side edge of the panel to the cut in the v-notch; 6" between the tops of the parallelograms; 3" between the bottoms of the p-grams; 6" for the length of the top and bottom p-gram lengths; and 1 7/8" for the distance from the tops of the p-grams to the bottom of the v-notch. -George
George,
George,
I could use a bit of clarification. I plugged in the new measurements but they don't add up for total height and width.
- From top to bottom, 2.3/8, 1 7/8, 2 3/8, 1 7/8 adds up to 8 1/4, but panel height is 9".
- Across top of panel, 1.5" top left corner to edge edge of v-notch, 18.5 of v-notch, 1.5 to top corner is 22.5, but panel width is 22 3/4.
- Across top of p-gram, 1.5, 6, 6, 6, 1.5 adds up to 21, but panel width is 22 3/4"
Are my numbers wrong as the angles on the cuts are not 45 degrees? Maybe panel is 22.5 wide?
George, I was totally
George, I was totally guessing on all of the measurements from looking at a picture of a back panel, so all you provided is excellent. I'll pass the measurements to MojoTone and see if they can make it. Really again, Thank you!

Soultrain65, I'll see the amp again on Monday at rehearsal. I will take all measurements again. The lighting is poor and the amp was against the wall, so...

Man, you rock! I blew up a picture of a back panel on my computer and took measurements yesterday, then made a cardboard template. I was pretty close to your measurements but will send you data to MojoTone to get the panels made. I'll let you know how they turn out!
You're welcome and thanks!
