Hey Guys - First post to the forum and hope all are doing and rocking well. I own a DSL40C and like most didn't care for the channel switch treble increase when going from the green to the red channel. Because this amp has so much gain I wanted to keep it low on the red channel. Well because of the cap marked C19 in front of the gain pot on the board it caused the amp to be way too bright when switching to that channel. Well I found out from a thread on TGP new Marshall DSL 40 and 100 cap "mod" - The Gear Page from a generous player TMAC about C19 being the culprit. See pictures of the cap in the link above. So this morning I pulled a leg of that cap out and voila, no harsh treble. Just a smooth transition from green channel to Red on Lead 1.
I don't know what Marshall was thinking putting that cap in but this amp is now that much better for covering Marshall tones in a small versatile pkg and probably so with DSL100H since its the same circuit. I do not miss a separate set of tone controls at all. Just a switch from a clean slightly breaking up amp to a thick juicy lead or rythm tone.
Sorry I don't have clips but it's totally a worthwhile endeavor to try it. If you don't like it solder the cap leg back in. Takes 10 to 15 minutes to do.
Also I would suggest using a low wattage iron like 25 watts or so or you got to be fast with a 40 watter when pulling the cap leg. Also be careful when messing around inside of these amps since they have lethal voltages stored up in the filter caps. If you don't know what you're doing have a tech do it.
Anyway thought I would share since so many players have experienced frustation from these amps being too bright on the Red channel.
Just for reference the only other mod I did is replace the 70/80 speaker with a G12-65 and put Electro Harmonix pre amp tubes in V1 and Mullard reissue in V2. I play mostly a mahogany maple capped strat with Van Zandt single coils and a Wolftone Marshallhead A2 magnet in the bridge.
Cheers
