Bias Switch; Send Level; Loop Select - Mesa/Boogie Dual Rectifier Trem-o-Verb Owner's Manual

34's. Make sure that the BIAS Switch is set correctly to match the tube type that you are using. Failure to do this will result in tube
failure that could possibly burn resistors in the Bias supply. Although this is a fairly simple repair for an authorized technician, it is
easily avoidable. ALWAYS CHECK THE BIAS SWITCH setting if you experiment with alternate tube types and you will enjoy
uninterrupted performances from your TREM-O-VERB.
SEND / RETURN: These two 1/4" jacks are the patch point for external signal processing effects. The Effects Loop in thewired in
parallel the TREMO is wired in parallel with the unaffected or dry signal which enables you to preserve the integrity of the all tube
tone and feel that the TREMO is capable of delivering. To use the Effects Loop for your processors, simply connect the Effects
SEND jack to your first effects' INPUT jack. Connect your last effects' OUTPUT jack to the Effects RETURN jack.

SEND LEVEL: This is the master SEND LEVEL Control for the parallel Effects Loop. The inclusion of this control makes it possi b le
for different channel specific volume levels to be used via the front panel channel MASTER Controls, while at the same time insuring
that you will not overload your processors' INPUT stage with an incompatible signal strength. For the best results, try this method:

LOOP SELECT: This 5 position rotary type switch determines the status of the Effects Loop. The Loop can be assigned to either of
the channels individually or active at all times (Loop on ORG. & RED) It may also be triggered remotely with MIDI controlled switching
devices by connecting the EXTERNAL SWITCHING jacks and selecting EXT. SW. on the LOOP SELECT rotary. As you might

SLAVE LEVEL CONTROL: This 1/4" jack and control provide a signal derived from the speaker jack. Perfect for using the TREM-
O-VERB as a master pre-amp, or additional power amps may be connected for more power when needed. Some players use this
to derive an FX Send Signal and go to other amps for their wet sound.
The Effects Loop interrupts the signal between the pre-amp and power section. Therefore, the RETURN
jack can double as a "Power Amp Input" jack. Remember that the Loop must be engaged for signal to
pass this junction. You will also want to run the MIX Control at 100% to use the Loop as a Power In patch
point.
NOTE: We suggest that when using the TREMO'S power section only, that you have the amp
switched to the VINTAGE ORANGE channel and the Channel Cloning switch set to "NORMAL". This
assures a more neutral power sensitivity thus making the TREMO more friendly to use as a power
amp.
1.) Set up the VINTAGE and MODERN channels to your preferred Gain and Tone control settings.
2.) Adjust the individual channel MASTER Controls to the desired listening level.
3.) Set the rear panel Effects Loop SEND LEVEL Control so that your processors' INPUT indication
LED is displaying the proper input signal strength ( hopefully unity gain .)
4.) Adjust the front panel LOOP ACTIVE MASTER Control to the desired level. See page 5 on: LOOP
ACTIVE MASTER - for more information regarding SEND LEVEL.
surmise, the ORG. AUTO position assigns the Loop automatically to the VINTAGE / ORANGE Channel
and every time the ORANGE Channel is called up, the Loop will be engaged. RED AUTO duplicates this
scheme for the MODERN / RED Channel. For you purists, the TREMO gives you the ability to remove all
Loop circuitry from the signal path completely by selecting the BYPASS LOOP position.
