technically I think you could it with an adapter (since it's XLR, unlike the TM) but I wouldn't recommend it, you might damage your cans and or your ears. What I do in situations like this is run the output of the rebel into a small (2 or 4) channel mixer that will allow you to control the strength of the signal and then use the headphone out on the mixer. That'll allow you to get some heat goin' on the rebel without killin' your ears or your cans. I have a little cheapo behringer mixer that I bought for about 80 bucks for just this purpose, works great for certain recording situations or when I wanna jam along with a track without buggin' the family or neighbors. Hope this helps. Did you get your tourmaster fixed yet?
