I recently picked up two Mark IV's, a transition A/B version Wood & wicker combo and a B version head. Grab and go is in jest? I do use the thiele cabinet in conjunction with the combo but the combo has to weigh 80 lb.s. alone, plus the ATA case and you're looking at "hey, can you give me a hand?" There is something about Mark IV's that I love that you can't find in any other amp. If you like Boogie's, this is the best of the bunch. My JP2C is awesome and my Mark IIC++ is a legendary monster of an amp, but the Mark IV for some reason just takes over and sends the tone to Heaven 11!!! It is so tough to choose which amp to bring!
I sent an email to MESA inquiring about modding RHY2 for more drive. They sent a generic email stating they received my inquiry and will get back to me within 72 hours.
