    The tone control wiring is right. Maybe the pot is bad. I've seen that with new pots before.

    Hey man so I changed the potentiometer and it works now, but I don’t seem to get any crunchy sounds like I’ve heard from other 5e3 it seems to be all clean tones, I really like the clean tones but I thought it would have a little bit of a crunchy sound and I played around with all the knobs and both channels, I couldn’t get anything but clean tones? By crunchy I mean something like la grange, i don’t really know the proper term.

    Double check your resistor values. I had a similar situation with lack of gain in my 5f1. Turned out to be a couple wrong value resistors choking out my signal.

    Did you use a 1 meg pot?

    ^^This please^^ Each tube every pin. This will let us know if voltage is where it is suppose to be and of the correct value. Also tells if voltage is where it should not be. heaters and the pt HT before the rectifier will be AC . The rest will be DC

    perhaps some fresh photos in good lighting WITHOUT FLASH

    Boot Hill shows a classictone 40-18002 6k6 - 8 ohm output transformer. What output transformer do you have?

    Dave often recommends the 6k6 OT.

    What guitar are you using. I find things pretty clean with that OT and single coils. Humbuckers can heat things up however.

    Ugh so I checked my resistor values and they are all correct, I didn’t check voltage i’m a little nervous about that but I guess it’s my next step, I have no idea what transformer I have whatever he gave me, I play a strat with single coils, I thought that my input jack area was where the problem was so I took out all the jacks and resoldered them, but when I fired it up there was a huge problem it started making a loud noise even with the volume all the way down so I just shut it off and it made a big pop, so the nightmare continues, I’ll try to redo the jacks again today and see if I can measure voltage at the tubes. Maybe it just won’t get crunchy? It definitely sounds different than the you tube videos I’ve heard?

    I had the 6k6 ot in my deluxe and it had some grind to it. Not as much as the 8k but, it wasn't totally clean. I've since changed it for the 8k ot which I like better.

    I checked my voltages:


    With no tubes in

    pilot light- 6.6 v
    Fils 12ay7- 6.6v
    Wy3gt pin 4 - 388v
    Pin 6 - 388v
    Pin 8-2- 5.1v

    with wy3gt, 12ay7, and 12ax7b

    wy3gt pin 8 510v
    Pin 2 510v
    Caps from left to right
    510v, 480v, 352v, the big orange one on the right side was 175v

    with all tubes in and speaker plugged in

    caps 379v, 340v, 251v, Orange- 126v

    12ay7
    Pin 1,6 127v
    Pin 3,8 2v

    12ax7b
    Pin 1-166v
    Pin 6-195v
    Pin 8-45v
    Pin 3-1.2v

    6v6gt both
    Pin 8-20v
    Pin 3-370v
    Pin 4-340v

    Hopefully this helps, it’s still not getting crunchy at all

    If everything is right does anybody have any ideas for getting a little crunch in the tone?
