is magic to your ears and to your hands. Simul feels great and is inspiring to play!
10 WATTS reconfigures the whole set of 6L6s so that the two nearest the 5U4 run pure Class A, single-ended—no longer push-pull.
This is the ultimate low wattage output circuit that duplicates the essence of the best really old vintage circuits. Here, the second
harmonic (an octave above the note played) is NOT cancelled out (as it is in push-pull circuits) and provides a magical halo surround-
ing the notes. Onset of clip is so gradual that it's hard to pin down the transition from clean to overdriven.
These three power choices give you ultimate flexibility as to the styles and venues the MARK V can adapt to instantly and in fact,
it's like having three separate amps in one case - each having the perfect amount of power for a different application. And when
you combine the power of the separate PREAMP Channels, the combinations of EQ and the POWER options, you have the most
comprehensive collection of tube amplifiers ever brought together in one chassis. That's a bold statement; but after you spend some
time exploring the combinations we're sure you'll feel the same.
OUTPUT & SOLO:
These two controls the overall output (volume) level of the MARK V when the EFFECTS LOOP switch on the Rear Panel is switched
into the LOOP ACTIVE (switch up) position. With the EFFECTS LOOP in the HARD BYPASS (switch down) position the OUTPUT and
SOLO are inactive and the overall volume levels will be determined by the MASTER control in the Channels. The EFFECTS LOOP
adds a whole stage of amplification and the OUTPUT and SOLO come after this stage. The HARD BYPASS feature is intended for
recording or solo playing environments where the balancing of the three channels is not so critical.
The OUTPUT control enables you to raise and lower the entire playing level of the MARK V without affecting the balance you have
set between the Channels with the Channel MASTER.
The SOLO control is a footswitchable Master Volume for the whole amp that is wired in parallel to the OUTPUT control. This allows
you to dial up a preset amount of boost and switch to it when it's time to step out for solo passages or any time you want to showcase
a part. Simply set your desired overall playing level with the OUTPUT, Select SOLO on the MARK V Footswitch and set the desired
increase in volume level with the SOLO control.
NOTE: The SOLO control may only be used to increase the volume beyond the level of that set by the OUTPUT. You cannot use the
SOLO to switch to a level lower than that set by the OUTPUT Control.
NOTE: Check the setting of the SOLO control before switching to it as it may be set high and cause a shocking increase in volume.
The STANDBY shuts down part of the high voltage to the power tubes so that they can rest at idle without wear. It provides a start-up
procedure (follow the Cold Start procedure... wait at least 30 seconds after powering up with the POWER switch before turning the
STANDBY to ON). This reduces the shock on cold power tubes and increases their life. The STANDBY is also great for muting the
sound during speaker changes and should also be used to cool the amp down during set breaks or when swapping tubes.
A built-in variac is included on the POWER switch so that you may run the entire amp on a reduced voltage "brown-out" condition. This
reduced voltage changes the sound and feel of the entire amplifier. SPONGY Power scoops the midrange and increases the sag to
achieve a more vintage, looser, easier-to-clip character. FULL POWER (BOLD) delivers maximum headroom, focus and punch and
is considered the "normal" mode of operation.
