Strange cab combo, but sounds great

[Ray 911S]

How's this for an unusual guitar speaker cab duo? On a whim, I had a custom jack wired into my Fender Rumble 100 bass combo. When a plug is inserted into the jack it disconnects the horn as well as the bass power amp feed so that only the 18" driver is live. I use this 1X18 cab as the right channel and my Marshall 4X12 on the left channel from my guitar head. For playing Blues on the Strat this is a really great sounding set-up! And I just unplug the speaker cable from the Rumble 100 and all is ready to go for bass.
