Okay, what brand was the 1x15 + 2x10? How many Ohm was the speakers?
The cabs were Mesa Diesels. Both at 8 ohms, running at 4 ohms. Definitely got loud enough for my uses, and we play decently loud. Not crazy, stupid loud, but as loud as your average rock band with two tube g**tarists and a heavy handed drummer.
My 1x15 always had some sort rattling or slight distortion issue, even before I had the WA and last week I finally found out that the speaker is sorta busted. That's probably why my initial tests with the WA weren't as good as I thought it could be. It sounded like I was farting or running out of steam, but this could have been a majority of it.
Also, I have an update on what I think about the 2x10 and 1x15 as individual cabs. I found that I might have set up my rig wrong when first playing through all my cabs. As I mentioned, no probs with the PH1000. But the 2x10 + 1x15 felt like I was taxing the power section. Well, after finding the 1x15 needs a speaker recone or replacement, I have to temporarily use just the 2x10. Initially, it sounded what I thought it would be at 8 ohms. Not loud enough, getting close to farting or getting farty when digging in the low notes. Also, not much lows except at certain frequencies. Overall just no consistency. Then I realized that after recording direct from my Sansamp BDDI, which I usually run into the front of the WA, that the BDDI was still in LINE output rather than INSTRUMENT! Rather than go back to INST output and still running in line, I decided to eliminate too many factors and just ran LINE output to the WA return jack.
MUCH BETTER! Lows were LOW and sustaining. Consistent across the board with a very creamy sound. I could definitely crank the volume with no sound of the speaker nor the power section starting to give out. Actually, I had to turn it down. Overall, much more headroom. Much more pleasant and enjoyable experience with a single 8 ohm cab. And now I see how and why people say that the WA is way more what they need with a single cab. I didn't have a chance to try it with the BDDI back into the front input or with just the bass straight to the front input, but I will soon.
So...? What went wrong here? I could be wrong, but I think I was overdriving the input. It sorta fooled me into thinking the WA just couldn't put out the volume I wanted it to. Is this a valid assumption of my experience? Or am I way off here? I'll make a new thread to ask this as it is part of my continuing quest to understand volume and clipping in relation to preamp / poweramp input balance.
Sorry to get off track, but basically I'm saying that when used correctly, even an 8 ohm 2x10 could sound way huge with the WA, if you know the cab is capable of doing so. (edit) And I wasn't even using the WA preamp that must everyone agrees is some of Mesa's best work. I'll definitely get this to work with the preamp, with and without the BDDI. And even if I don't, well, the Walkabout is one sweet little poweramp with an insurance plan!
