    Some specific directions, the cap #, location would be helpful.

    thanks

    i haven't done one for several years but it is tedious, in that, you have to pull all the pots because they are PCB mounted and the bright cap in on that board...instead of removing it, i would recommend snipping one end of it so that if you ever need to connect it again, it will be easier...i believe it is labeled C10 and located between the 2nd input jack and the Volume pot on the vibrato channel.

    I have open the chassis.
    I cant find c10 on the board. I looked hard. And I cant look at the pots as the green board is covering it. Do you think it across the volume pots instead of the board?

    Here is the schematic:

    If it is c10 , then there is a c2 on the normal channel....should we snip it as well?

    you HAVE to pull the pot board because the cap is on the side beween the board and the chassis (hidden)...that is why it is a pain in the ass...

    do NOT snip C2...it is part of the tone stack...

    Ok sir,

    The job is done. Definetly takes overdrive better now.
    Though still not as i would want it. Maybe a speaker change is needed.

    I left c2 as is.

    Yes it was a pain. But got to checkout the innards.

    Something learnt.

    Thanks again.
