Hi there Guys,
I have just purchase a CMI amp, not Guitar so am proable in the wrong forum,
but like everone else I know very little about them, Mine is equipted with 3 10′ celition red lable speakers (never see 3 in one cab befor) and is named the MAXIMIN 30 W tremelo Master (which i belive equates to a pitch/ wave range ind amplification terms), I also know that they were fairly unsucessful as a cheap amp in the 70’s and only made for 1 year 76-77 I think. and also many did not make it past the proto type stage mine says July 1977 Z501 as a serial number 🙄 on the back. any info or direction to another sit would be a great help I will try and post a pic, (havn’t recieved the amp yet and will send picks of the inside when it arrives. http://www.imagestation.com/picture/sraid202/p3929fc28e23ef1f0f187d1d1c13afb3b/efae4380.jpg.
