Go Dante  , and I made it sticky and locked so it doesn't get surrounded with posts like the mod and schematics, Dante we need to fix that but I can't work out how to move an individual post, topics sure but not a post within a topic

Is there a mod that expands or adjusts the EQ?

[MarshallJMP]

Take a look at the mod3.666 there is a section on modifying the EQ.

What does the acronym HDRM on the preamp schematic mean?
I have searched the net but cannot find it.

What does the acronym HDRM on the preamp schematic mean?

Looks like it either stands for High Data Rate Multiplexer (a digital data splitter) or Hold Down and Release Mechanism. My guess is it is the latter and it is referring to a connection to the front panel membrane.

HDRMs are the signal monitor points that go the clip LEDs on the front panel. Probably short for Headroom.

FYI: I added a bunch of MP-1 Classic schematics yesterday (thank you Sparker!!)
