Awesome, thanks! I played with it more seriously today in the practice space. The volume/gain thing is so weird compared to the Mark 3s! It kind of seems like:
- With a Mark 3 if you set the rhythm channel to overdrive, you can hear it start to make the lead channel a bit fuzzy, loose, eventually noisy. If you back off the rhythm just below where it starts overdriving, the lead channel sounds normal.
- With the SP, the rhythm channel gain sounds pretty similar to the Mark 3's when you're running it hard. But overdriving at that stage has a much more drastic effect on the lead channel, and you have to back the rhythm off way down into its clean range before the lead channel settles down.
- I could see this bugging me if I was planning to switch between channels on the fly, because I have to lower the rhythm gain so much that the lead master ends up being at like 1 in order to get the channels even close to balanced, and there seems to be some cutoff point where setting the lead master too low suddenly makes the lead channel sound all weird and fuzzy.
Anyhow, I swapped a 12AT7 into the lead position and that helped a lot
...now I can get overdrive around 4-5 instead of 1-2 (which is good because it drops off hard around 1), and running it flat out doesn't get too crazy. I still have to keep the rhythm gain low-ish though, because turning it up past 4 or so does something to the lead channel that even the lower gain tube doesn't tame. Weird!
I guess the plot twist here is that this is mainly going to be a bass rig, taking the place of my D-180. I am excited to try it on guitar too, especially considering how different it is from my Mark 3s.
