Dean Markley Signature 120 Schematic?
« on: March 08, 2015, 08:45:08 pm »
Just curious what this amps circuit is based on. I hear Bassman and Marshall thrown around online but would love to see the actual schematic.

Plexi, this is what I've been able to find. Most likely you've already seen these....

Probably the soundest most accurate thing I read was "contact Dean Markley directly and ask".  :laugh:
Hope this helps!
Tapping into the inner tube.

Thankyou John for your research time and info. I ran across those links as well. Sort of bits and pieces of info but nothing completley dedicated to the Signature Series 120. I think i will just pull the amp from the rack and take a bunch of detailed pics. Write down what i see and create a layout.  I guess i could email Dean Markley as well and see where that takes me.  Thanks much. :icon_biggrin:
