Cheers! I'm a 50+ novice guitarist (<2 years) and I purchased a DSL5CR a few months ago, so it's well run in. It was an upgrade from my Vox Mini SuperBeetle (looks amazing, sounds good) and I'm very happy with it. It looks and sounds great. I play almost exclusively in 0.5 watt mode and am very happy with the tone I get at reasonable volume levels. As I'm improving as a player, and as my ears are becoming more attuned to tonal differences, I am starting to recognize that while very good, there is room for improvement in the overall sound. Today I removed the back for the first time, verified that I could disconnect the speaker leads easily, and I removed, examined, and took pictures of each tube. I was pleased that I was able to put everything back together and that everything worked the same. Having done that, I'm looking for some advice and recommendations. I need to buy a new set of tubes. I plan to replace all 3, with a goal of having a full set of known good replacements - the old ones - and a possible upgrade in tone. While I know there is room for improvement, I don't know enough to fully articulate what I'm looking for - sometimes I want a little more brightness, sometimes a little more warmth. Can anyone recommend a tube compliment that would achieve my goal of being subjectively "better" while not messing with the overall characteristics of the tone, which I like? Second, I'm considering a speaker replacement. I have 4 candidates with a goal of keeping this change under $100. The stock 10-30 sounds decent, but even my newly trained ear can hear limitations. The highs can be a bit tinny when I attack hard, and while I like the distorted tone, it can be a bit messy. Not sure if that's the right way to describe it, but it's the best I can come up with. I'm considering all Celestions, if only because the seem to be a general tonal match to Marshall circuits. I'm considering a VT-Jr for $60, a G10N-40 for about $70, a Greenback for $100, and a G10 Vintage for about $95. Is the VT-Jr a real upgrade? It's only $25 more than a new 10-30, so I'm a little hesitant. If it doesn't sound much better I could always throw it in the Vox and try something else. I look forward to any input. I've been reading the forums quite a bit and have learned a lot, but it was high time I signed up and put my questions out there. Thanks, all!
