WOW

though it doesn't exactly emulate any particular amp's response you will not believe clean and dirty tones of this caliber can come from a solid state amplifier in an MXR sized enclosure. The microblock eschews the fancy tone shaping features of the larger quilters in favor of a streamlined no-nonsense amp that fits on your pedalboard. It won't replace my vintage vox, but its definitely the finest backup amp money can buy.... and its not a lot of money! I'll always have this on my board at a show along with a super long speaker cable just in case. Get one.
