your local Ampeg Dealer, or directly from
shop.ampeg.com.

(unbalanced) cable from this 1/4" output to
send a line level signal to an external effects
processor. The output here is affected by all
controls. Use the Effects Loop Return jack to
feed the returned processed signals back into
the power amplifier—see item 21 (RB-112,
