    It's still getting there, one circuit diageam, kinda... its kind of a diagram/layout.

    As a few may know I've been trying to trace the circuit of my amp without a schematic, because one isn't in the public domain yet, so I could look into some of the modifications I'd like to make.

    PPIMV type 3
    Switch for the fx loop
    And I now want to change out the LED, becauee somebody else did and now it looks cooler than my amp so I want in! :-D
    I may look jnto the ao called 'metal mod' or settle for the one wire mod... but, this is where im at with the diagram.... All I can say about the gap between V2 and V3 is that it somehow goes from the 330k slope resistor, down to the bottom, around the power reduction section and back in below the Phase Invertor.... if somebody want to have a go at the rest, or the reduction section, good luck to ya!
    Imma getting my mods done and out of it! :)

    Since there is no schematic yet, there is going to be a limitation on modification.

    Hi
    I also have a 50c

    I am trying to figure how take a tad the bright of the Boost only. Maybe if I put a cap between some legs of the pot it would work....

    But having no schematic is quita a try and error thing

    Anyway, is quite new, will let it break in through one year or so before doing anything

    Based on my experience, a V30 will add more highs!

    I put all mullard preamp tubes in mine and it seems to have taken a bit of the highs off, mine is also a head being run through an MG cab with 2 greenbacks in it.

    I'm am quite amazed at the outcome so far.I have been using my Modded monte allums SD 1 pedal and also my home made GGG TS 808.
    Amazing warmth and clarity and very pedal friendly.
    I keep my Line 6 DL 4 permanently on in the FX loop and that helps too.
    I'm playing a Gibson Les Paul.

    I have a 20, dont know if they are much different than the 50 but I like how it pairs with my home made open back 12" Hellatone 60 cab.
    These are phone recordings but they get you an idea of the tone. I also have an orange 1x12 with a V30 but its still getting broken in.

    Sounds great brother, I only purchased the 50 because my grandson is a hard hitting drummer, I demoed the 20, liked it enough to order the 50.
    Cheers
