When the Custom Valve 40 was getting rave reviews in the all-tube combo amp market, Traynor responded to the demand by expanding the line with the addition of the 2x12" Celestion™ loaded combo Custom Valve 80 - YCV80.

Two new tone-shaping controls give players unprecedented tonal variety for nearly any vintage tube tone. A 'Scoop' switch on the lead channel adds body for much heavier leads while the 'Expander' switch on channel two equalizes certain frequencies to create crystal clear new rhythm sounds - often simulating an acoustic-like tone from an electric guitar.

A parallel effects loop with separate input and output trim pots for better overall effects control and a series effects loop (or loop through) between the tube pre-amp and tube power stage give the performer more flexibility over the signal path than found on other amplifiers.
