Convertible amps are designed with Accutronics 2-spring reverbs. These are the most
natural sounding reverb units available and they provide a wide range of reverb for your
playing styles.
7) PENTODE/TRIODE SWITCH:
This switch changes the operation of the EL-34 output
tubes, which use five components inside each tube. With this switch in the up position,
the tubes run in the Pentode mode and all five components operate for full 100-watt
power. The sound is brighter and crisper.
With the switch in the down position the tubes run in the Triode mode and three
components operate for 60-watt maximum power. The sound is smoother with a little
less edge. Experiment with this switch to find where you like it for your musical style.
Some amps have
60/100-watt
switches. What they do is turn off the voltage to two
tubes. That causes the power to drop but also places stress and wear on the two tubes
that are on. The Pentode/Triode switch allows all tubes to run stress-free and provides
longer life to all the tubes.
8) VARIABLE DAMPING:
This circuit is included with Convertible amps to give you
more control over your sound. Damping is the amount of control the amplifier has on the
speaker. High damping (turning the control to the right) increases the control of the
speaker - the sound is crisper and tighter. Low damping (turning the control to the left)
decreases the control of the speaker - the sound is looser and fatter sounding with
slightly more presence.
There is no recommended setting because only you can tell what's best for the sound
YOU want to produce. This control is effective ONLY when the speaker is connected to
the "Variable Damping Out" speaker jack.
9) 4 OHM, 8 OHM SPEAKER JACKS:
You can use these jacks to match the amp
impedance to the input of the speakers you use. Proper connection to these jacks will
give you maximum power and maximum damping.
If you choose to run an 8 ohm speaker in the 4 ohm jack, no damage will result in the
amp or with the speaker, it will just sound different from being played through the 8 ohm
jack. The same situation is possible with a 4 ohm speaker in the 8 ohm jack.
You can also use all three-speaker jacks at the same time with different speakers. The
Convertible amp's strong transformer can handle almost any load with no damage.
10) SLAVE OUT:
Use this jack for patching the output signal of the amp directly into a
mixer, tape recorder, or another amp. Just use a regular guitar cord from Slave Out to
the guitar input of the other unit. The circuit is wired after the output stage so all tone,
volume, damping control, effects loop,
etc. controls will affect the outgoing signal. Output
is one volt at full power.
