Searched but not finding..... I would like to add an LED to the front panel to tell at a glance whether the green channel is in Clean or Crunch mode. Has anyone done such a modification? It does not matter to me whether the LED is lit in Clean mode or Crunch mode, as long as it’s on in one mode and off in the other mode. Presumably it’s as simple as clipping one side of a particular resistor or something, and inserting the diode at that point.... if anyone is familiar enough with the circuit, please chime in
This is a 40c and an a origin 50H, both amps are being used as heads, through mg cabs, just wanted to share the tone

There's a video on YT where a guy added an LEDs to his foot switch so maybe it would be similar?

That one looks easy once the values are known. The clean/crunch indicator will be different. Ideally I could just tap the switch itself, or even better install an led button switch. But I’m not gonna remove a board-mounted switch. Too much potential for problems.
I'm sure I am preaching to choir here but here is what I ended up doing to my DSL40C. The bias on the power tubes was crazy high. 49 on one and 47 on another! Changed speaker to a Celestion Elite 50 Put a NOS RCA black plate 12ax7 in V1 JJ EC83 in V4 Kept stock power tubes and biased to 34.5 Favorite pedals so far are EHX Soul Food and a Dyna Comp with gain cranked on green channel clean and red channel lead 1 for solos. I didnt find a need to clip c19 because the fizziness was easily rectified with the speaker change, bias, and RCA in v1 and eq's dialed right. Tremendous amp. I do wish they'd have at least made the baffle board out of plywood or pine but I got by. Just not changing the speaker again. This ones a winner in there compared to the 70/80. Oh and also hit all pots and inputs/outputs and tube sockets with contact cleaner.
The Soul Food is a great pedal. I'm running an OCD into my 40C, which I didn't like that much until a speaker swap. After the swap, the OCD gives me this tweedy, Bassman-like low-end grit that I love for bluesy stuff. As much grief as I might get for this, I skip the green-crunch setting entirely now - I keep the green channel squeaky clean, I use the OCD for moderate crunch, then use the red channel in lead 2 with the gain dialed back to about 2-3 for heavier stuff. It's a perfect rig for me; I have no desire to change anything up right now.
Be careful with using Contact Cleaner in your pots. There’s another thread on here about the difference between contact cleaner and deoxit and the outcome was to use deoxit on pots because it has lubricants (that pots need), where as contact cleaner doesn’t and will dry them out. Great mods and good to hear your enjoying the DSL!
I used deoxit 5 on my tube pins to clean it, didn't seem to harm it but I learned about the solvent thing after i bought it
Here’s a few seconds of the DSL40c. Sound is Strat into a PitchFork (you’ll notice where I use it), but aside from that unadulterated. Captured from about four feet away on my iPad, the combo’s Creamback plus a 2x12 all firing. Classic gain, Crunch mode.
Thanks! I use the PitchFork via an expression pedal. On that song, it allows me to emulate the keyboard parts and the octave guitar riffs. Aside from that, it’s pure Marshall.
