up this effect for over-use can be ineffective and can even dilute what might otherwise be a nice sounding tone. External switching
of the TREMOLO is possible by a remote footswitch, see section on External Switching.
To obtain the smoothest TREMOLO effect, bear in mind that for every range of speed - there is a sweet spot on the Intensity
Control. This is especially true for slower speed settings. Generally speaking, the slower the speed - the less intensity, while faster
speed settings would require just the opposite. Getting the slow speeds to sound smooth may be a little tricky at first, for they are more
obvious when they are not optimized. Exercise patience and learn to blend the more active power of the Intensity Control tastefully for
these slower TREMOLO effects. Understanding the interaction of these two controls is crucial for obtaining great TREMOLO in your
TREMO.
POWER / ON: This switch delivers the A.C. power to the TREM-O-VERB. Make sure the unit is grounded (all three terminals of
the A.C. power cord must be connected whenever possible to avoid injury to the user as well as to the unit) and that the
proper voltage is present. Follow the cold start procedure described in the ON / STANDBY section below when
powering up your TREM-O-VERB.
ON / STANDBY: Perfect for set breaks... this toggle switch also serves an even more important purpose. In the STANDBY position
the tubes are at idle so that during power up they may warm up before being put to use. Before power is switched on make sure the
STANDBY switch is in the STANDBY position. Wait at least 30 seconds and then switch the STANDBY to the “ON”
position. This prevents tube problems and increases their toneful life substantially.
REAR PANEL:
POWER SELECT: The two different power selections of the TREM-O-VERB are equally important when looking for a particular
sound. “Spongy” works like a built in Variac, reducing all the internal voltages for a true vintage feeling and that extraordi-
nary “brown sound.” Power is reduced somewhat too, making it easier to achieve an overdriven power sound, especially when the
Rectifier Select switch is in the Vacuum Tube position. Using the TREM-O in this power setting will also
extend tube life and overall reliability, while still producing enough power to work many of your gigs...and
all of your recording needs! With the TREM-O-VERB’S POWER SELECT Switch in the up position,
maximum power, clean headroom and volume are obtained.
FUSE: This is the A.C.’s (Alternating Current) main FUSE and provides protection from outside A .C. fluctuations as well as power
tube failure damage. Should the FUSE blow, replace it with the same rating in a Slo-Blo type package. The domestic U.S. version
requires a 4 amp Slo-Blo FUSE. A power tube short or failure is often the cause of a blownFUSE...Follow the cold start procedure
mentioned in the ON/STANDBY switch section and watch the power tubes as you turn the STANDBY to the ON position. If a power
tube is going bad or is arcing you will see it! Turn the STANDBY switch to STANDBY immediately and replace the faulty
power tube and the FUSE if necessary. If you see nothing abnormal as you lift the Standby, it is possible that a power
tube shorted temporarily and blew the FUSE. If this is the case it may work again normally. To be extra safe, you might
want to replace just the adjacent tube or all power tubes in the “shotgun” troubleshooting tradition and save the re-
placed set as spares. See page 13 and 14 for more information on tube replacement.
