Hey guys. I got a Peavey TNT 130 combo with a 15" woofer inside, and I am planning on getting a 4x10 cab and a pretty powerful head. I was wondering if i could use my TNT as an extension speaker instead of buying another 1x15 cab. I really like the sound of that TNT and was wondering if I could do it. As for inputs it has a high and low gain input and a power amp input. Let me know what you guys think.
