Randall EOD 88 User manual

EOD88 OPERATION MANUAL

Congratulations on the purchase of your new RANDALL EOD88 Amplifier! Some things in music are obviously inspired. There is a
famous interview with!Ozzy in which he talks about how Black Sabbath’s sound evolved in the early!days: “We were just a blues band
and then it took on an ELEMENT OF DOOM…”

So, In the spirit of that early pioneering of heavy metal, we have created the EOD88. With 3 gain modes, KT88 power design
and a built in fuzz circuit, this amp personifies old school but within a fresh modern approach and appeal.

We at Randall Amplification appreciate that you chose the EOD88 head Amplifier and wish you years with tons of gain, great
tone and enjoyable playing time. Please review the safety instructions below and be aware that the documentation provided in
this manual references 120volt USA versions of the models covered.
Note that the POWER listed on the back of the unit should be for your countries’ power standard.

“This apparatus is for professional use only.”
