Great Great Great!

I have the 100w combo but liked it so much I wanted to use it with a fantastic 2x12 vertical slant cab I have loaded with Eminence Cannabis Rex (which are also fantastic). It contains a 3 inch internal speaker for home practice. This think absolutely kicks a$$. I use if for rehearsal with no cabinet and it more than keeps up with the drummer on the 50w setting. No cabinet hooked up, just the internal speaker. I also have a Mesa Express 5:50 and Hughes and Kettner Grandmeister 36 but they are sidelined for now. This head really does sound incredible and more than that, it FEELS like a tube amp. In conjunction with the Tone Studio software and full updates, this is amp is a beast. So so versatile, The effects are even more than solid. Boss has really thought this platform through and have come up with a solid winner. My Yamaha THR is gone. If you're on the fence, just get it. I am astounded at the quality of this little rig. It will be my go-to for some time. Everyone should have one in their arsenal if they are a working musician. And the head even without a cabinet and internal speaker alone, will more than satisfy the home player.
