Don't own any, but I once got to play through a Maz Jr. They are great boutique amps. Warm, sweet tone that practically brings tears to your eyes when you play through one. Ultimate blues/classic rock toned amps.
It's because of that Maz Jr. that I love EL84 tone so much. 18 watt Marshalls and clones thereof have that same kind of warm sweet OD tone. Since I'm not quite ready to fork out $1000.00 + for an amp right now, I just get by with my EL84 loaded Vintage Club 30, VC 20, and my Epi Valve jr.
