I received my Blues Machine yesterday. I think it just may be my last amp because it can do everthing I need WITHOUT ADDITIONAL PEDALS! I had a Tweedyverb that was great but I play about 75% at home and the it can get loud, even on it's low power switch and with 6V6s. The Blues Machine's master volume is exactly what I was looking for because I can set all the controls where I need them and then just use ONE knob (master volume) to control the volume without changing the tone or overdrive. It's pedal controls the Tweed, Drive and Boost settings so that gives four settings plus you can combine them for even more overdrive options. Also, it's cathode/fixed bias switch, smooth switch, humbucker/single coil switch and effects loop makes it way more versatile than any amp I've ever owned. It has plenty of clean headroom in the blackface setting and can get very LOUD. I don't see why anyone would need more power than this amp has. I got it with an Eminence Lil' Texas Neo magnet speaker and it sounds as good as I hoped it would. It sounds very close to the Jensen Neo 12-100 speaker and that is exactly the sound I was looking for. This Blues Machine weighs in at about 42 lbs which is only 5 lbs more than the Tweedyverb. I'm also looking forward to trying a volume pedal in it's effects loop to be able to control the volume while playing. Henry said this will work just like the master volume control. Has anyone tried a volume pedal in a RedPlate effects loop? For me, the Blues Machine is the perfect amp. Thank you Henry!
