I run my SG through a mini Tumnus set at unity gain, with just the slightest overdrive, in front of the OR15. In the loop, I use a Zoom MS-50g for graphic eq, delay, and reverb (HD Reverb). For me, it's the perfect combination. The Tumnus enhances the harmonics at this setting (Tumnus...
Did this problem exist with the old, original power tubes? I suggest reinstalling the old tubes and checking bias,
to see if the problem is originating in the tube, rather than a bias resistor.

You have perfectly described my favorite od pedal:
Even the color is my kinda thing. I set the volume at unity and leave the gain at 8:00 for an extremely low, "transparent" effect.
That's exactly how I acquired my DSL 50. Dude sold it to me cheap because it had crackling and very low output. I took it home, assessed that one of the power valves was blown, plugged in some matched JJs, then biased. It's been faithful ever since that day.
JCM 2000 DSL 50 models do not appear to suffer from bias drift. How do I know? Aside from my DSL 50 showing no symptoms, all the research I have done (on the bias issue) points to the DSL 100 models as mentioned in charveldan's post above. :)
Come on, Marshall, throw me a frickin' bone. I didn't get the "buy one get one free" 2-fer special when I purchased my 100h! I didn't even get a shmoke and a pancake!
Then, come to think of it, what would I do with two? My DSL 100h from 2014 has functioned flawlessly since I first flipped...
As an owner of both a JCM 2000 DSL 50 (made in 2000) and a DSL100h (made in 2014), I can honestly state that the 100h is as reliable as the JCM. I run it in triode 50w mode, with all of its original factory tubes, and have never had any issue with it. The JCM has a Drake OT, and a new set of...
