I use this combo since couple of moths - it works/sounds perfectly as stand alone combo, with my HX Stomp and Roland GR55 synth. I use the DV Mark Little Jazz Combo on a daily basis for practice and for small chamber concerts - especially when I have to perform as a one-man orchestra. When it needs more power, I add external PA. Sometimes it is paired with the H&K TubeMeister 16 twelve in a stereo system. Then I use the distortion on the tube preamp, sent to the HX Stomp, and the stereo output signal returns one channel to H&K and the other to the DV Mark Little Jazz Combo - a wonderful, light, practical, and first of all, a great-sounding amplifier :-)
