I just bought a new rig for my loft space, and I'm between deciding on whether I want to keep the DSL1 head or the 20. I'm running through a Victory vertical 2x12 and using Suhr, Ibanez, and Fender guitars right now. Also using a pretty decent pedalboard for boosts and loop fx. I'm genuinely surprised by how good the DSL1 is. It's thick, more vintage sounding on the ultra gain channel than I'd imagined (within the lower regions), but easily boosted into 80s territory with a klon clone. The fx loop works great. The MV is right on. Even the reverb sounds good to my ears. The only problem with this amp for me is the clean channel. It's very thin and trebley, and it doesn't take gain pedals at all. At least, not at reasonable volume levels for in house playing (i.e. loud stereo levels on a £3k + setup -- no waking baby/annoying wife/sound of strings stuff here). In comparison the 20, and I'll admit that I've played it less than the 1w, feels lacking to me. Maybe it's because I can't get the tubes cooking, who knows. It just doens't give me, at the minute anyhow, that great Marshall tone that the 1w head gives me. Takes pedals slighter better on the clean channel thanks to the gain pot, but still nothing to write home about in that dept. Something I do like, however, is the standby switch. So what are your thoughts on the above? Interested in all opinions and shared stories if you've used or owned these amps. I'm tempted to try one of the 50th anniversary heads instead as I've heard that they take pedals better on the clean channel?
