TWEAKER-88

1) AC INLET and FUSE: Connect a

universal IEC type power cord. Be sure the

proper value fuse is installed that matches

the ratings as indicated for your country on

the rear panel.

2) AC VOLTAGE SELECTOR: Makes

the Tweaker-88 compatible with the line

voltage in any country. Proper setting of

this switch is absolutely critical. Be sure

the switch position matches the line volt-

age in your country. Severe damage will

result from improperly setting this switch

and will void your warranty, as well as

destroy your amp. To change the setting,



screws securing the plastic safety cover

strip over the switch. Swing the cover

aside. Using a small screwdriver, slide the

switch to the proper setting. Replace the

cover and retighten the screws. Be sure to

install the proper value fuse.

3) TUBE FUSE: This fuse is directly

connected to the power tubes high voltage

supply. In the unlikely event of a power

tube failure/short, this fuse will open. If

this happens, it is a sure indication of a

defective power tube.

4-5) FOOTSWITCH: The Tweaker

88 footswitch has four pushbuttons for

control of channel switching, the effects

loop and the individual BOOSTS for each

channel. The cable splits into two ¼” plugs

coded to match the jacks on the amp.

6) EXTENSION SPEAKER OUTPUT:

Used to connect a second speaker cabinet.

Since the MAIN speaker is labeled USE

FIRST, it would reasonable to assume

this jack could be labeled USE SECOND,

which would be correct. See the section

later in this manual for proper connection

and IMPEDANCE SWITCH settings for

different speaker arrangements.

7) MAIN SPEAKER OUTPUT:

Labeled “USE FIRST” because you must

use this jack….FIRST. There is a special

circuit inside the Tweaker-88 that helps

you forget to plug in the speakers and at-

speaker load connected…but we didn’t

have to tell you that, did we ?

8) IMPEDANCE SELECTOR

SWITCH: Set this switch to match the

IMPEDANCE of your speakers.

9) EFFECTS LOOP: Basically a series

insert patch point between the preamp

and power amp. When an external effects

gadget is patched into these jacks, the path

is interrupted and 100% of your signal is

routed through the effects. This puts some

special demands on the effects unit. First,

the effects unit must be essentially trans-

parent, meaning it can’t mess with your

tone. Second, the input and output levels

lowest noise and maximum headroom.

Proper setting of these controls can be

achieved using the following method:
