Been trying to dial in my DSL40CR at home. Home is a single family home not an apartment and I do get to play louder than the stereotypical bedroom player ( when the wife is not home!) Per my free db meter iphone app I go up to around 90 db. Not loud at all but not the kid in the bedroom trying to not piss off mom and dad either. Still not in the sweet spot for the amp. Considered the C19 mod, and am adding a 1x12 ext cab with some kind of speaker to make it a little less harsh at my available levels of volume. Then as a semi - afterthought I stuck my Plexi Drive deluxe in front, on the clean side of the classic channel. It actually sounds pretty nice. I didn't get a lot of time to dial it in, but first impressions are that I can get a good Marshall sound without the less than desirable harshness that comes with this amp when not turned up a good bit. It would also save the C19 for when I can let it loose. By many accounts that I have read the C19 is a good thing when the amp is cranking hard. The other plus with this setup is that I can avoid the volume difference when switching between classic green and Red. I can use clean green, then bump it with the Plexi Drive. I think it adds options across all channels. the purist in me hesitated liking this, but if it's okay for a Jubilee to have a clipping diode then this can't be too un kosher, eh? I have considered actually looking into a modeller like Kemper, Fractal, etc to solve the volume vs tone dilemma, a Plexi Drive is still way more pure than that too LOL I might also try my Brute drive but I think that would drift farther from home re: solid Marshall rock tones. No harm in trying though. I initally got the Plexi Drive to get British with a Fender, and it did a nice job of simulating a Marshall, but dang does it seem right at home in front of a Marshall.
