Gentelman "pfschim" uses and loves his 12" combo with 15" extension cab.
thanks for the kind reference.
yes, I have a WA 12 combo (4ohm) and a Scout 15 (4ohm). I have used this rig on about 20% of my gigs over the past 2 years where I need more volume and overall coverage.
I am very happy with the WA stand alone, and use it this way most of the time. But, no matter how nice an amp it is, it's still only a 1x12 after all. When I stack these two I am running the WA at 2ohms and getting about 500w into two well matched 4ohm cabs. The added flexibility of the dual "player control network" is pretty nice on this rig too. I set the 12 to a 4k or 3k crossover, and run the 15 at 5k. Tweet on the 12 is nudged just a bit, tweet on the 15 is rolled off just a bit.
Great, Big, updated Old-School tone with my Fender/Lakland/Lull 4's.
If you have a specific question .. post it, or PM me and I'll be happy to respond.
Having said all that ... let me also say that I recently picked up an Accugroove Tri115 and it has started to take the place of the Scout 15 more frequently when I need the bigger sound. It's a great combination, with the WA 12. the Tri115 really fills out a full range of freq's (bigger cab, dedicated mid driver, sweet soft dome tweets), where the Scout does the full low end and low mids, but not as much of the mid presence as the Tri115. Downside is that there is an ohms mis-match with the Tri115 .. it's 8ohms vs the WA 4ohms, so I am not getting balanced power application to both cabs. Ahh well, there is always something to work out, isn't there ?
enjoy!
