Mic Eliminator works great. Sounds just like what is in front of the speaker without the hassle of setting up 2 mics (I run my MTS rack and G-Flex in stereo)
The only thing I had to do was change the speakers to match the impedance of the Mic Elim. I've used a Hellatone 60 in an old Peavey XXX 60 combo, so I went with them again, but with the 60L instead. Nothing like a pair of aged Vintage 30's with lower response.
BUT the Genz Benz speakers are quite good, and was quite happy with them in the cab...
The only speakers I never liked in the cab was the Peavey EVH speakers... sounded like poo...
