Congratulations and thank you for 
purchasing a professional tube ampli-
fier from Bad Cat. As with all Bad Cat 
products, your amplifier is designed from 
the ground up to provide the very best 
tones possible in a rugged, reliable pack-
age. Each one of our pro quality models is 
constructed with Bad Cat’s commitment 
to making the highest quality, hand-built, 
American-made amplifiers.

CAUTION

With a little care and caution, your Bad 

Cat amplifier should provide you with 

years of trouble-free operation and 

enjoyment. Please avoid damp areas and 

moisture during operation of the amp 

and in storage. This includes placement 

of beverages near or on the amp that 

could spill into the amp’s chassis. Liquids 

can easily damage tubes, switches and 

other parts. Immediately disconnect the 

amp from power source should a spill 

occur and dry the amp thoroughly prior 

to switching on the amp again. Drying 

may require the complete removal of the 

chassis from the cabinet and the removal 

of the tubes for cleaning. Avoid tipping the 

amp, using it in unbalanced positions, or 

lifting it unassisted to awkward heights. A 

little common sense will go a long way in 

making sure the amp does what it’s sup-

posed to do: provide you with dependable 

operation and great tone on a consistent 

basis.

GROUNDING

Please check thoroughly that the ground 

tip on the power cord plug is connected to 

true ground prior to operation of your Bad 

Cat amp. Using unfamiliar junction boxes 

can cause potentially dangerous floating 

grounds. Please do not cut or defeat the 

ground tip. 

FOR YOUR RECORDS, YOU MAY WISH TO RECORD THE FOLLOWING INFORMATION.

HELP SECTION

1) AMP WILL NOT TURN ON

  Check the power to the amp. Check for tripped circuit breakers, unplugged extension 

cords or power-strip switches that may be turned off. Check the fuse. If a dark brownish 

color or no wire can be seen within the glass tube, then replace. The amp may be perfectly 

fine but occasionally a fuse may blow because of high AC voltage surges. After the fuse 

has been replaced with the proper Slow Blow value and if the fuse fails again, the amp 

will require servicing.

2) NO OUTPUT with POWER light ON

  Tubes damaged in shipping will be the primary reason for your amp to not function 

properly. Please give us a call to help guide you through this simple repair.

3) KEEP YOUR AMP LOOKING NEW

  Use a damp cloth to wipe the controls on the front & rear chassis panels. Wipe the black 

vinyl covering with a damp cloth.

Operating Manual

 

TREM CAT 30

  SINGLE CHANNEL, 30 WATT, EL84 

Start with the rich chime of the EF86 side of a Black Cat 30. Add lush reverb and pulsating tremolo 

and you have one of the finest single channel amps ever made. A 4 - EL84 30 watt power platform 

running in Class A provides the engine. The Trem Cat is a Guitar Player magazine Editors’ Award 

winner and perhaps our most versatile single channel amp. 
The tone circuit is truly unique and affords unparalleled control over your tone shaping. There are 

two basic tonal options available. First, our five 

position tone cap selector and our standard bass and treble tone stack. The selector switch is the 

key to dialing in your sound. Position one bypasses the tone stack altogether and feels like you are 

plugged strait into your output section. Position two activates the five way tone selector. Allowing 

you five choices of tone caps and affording great control over the bottom end and thickness. Posi-

tion three moves you over to the bass and treble controls. 

Here the amp has more of a scooped hi-fi type of feel. Lastly, position four engages both the selec-

tor and the bass and treble controls. 

Between the cut control which adds high end sparkle, near infinite tone shaping can be had here. 
A master volume that can be switched out of the circuit along with a half power 

switch insures that you can get to any level of gain at just about any volume level.

Speaker Out

This jack is adding an extension speaker cabinet to be 

used with the internal speaker of the Tone Cat. The internal 

speaker runs at 8 ohms for a single 12 or 4 ohms for a 2x12 

and is parallel with the extension speaker jack.

Speaker Impedance

 

On a combo this rotary selector knob comes set at 8 ohms 

for a single 12 or 4 ohms for a 2x12. The selector knob can 

select between 4, 8 and 16 ohms. Check Ohm’s Law if us-

ing an additional extension cabinet to select the right ohm 

setting. Example: 8 ohms + 8 ohms = 4 ohm setting.

On a head, please be sure to select the proper ohms to 

match your cabinet. 

Speaker Phase Switch

This switch changes the phase of your amp’s speakers. 

When the amp is played by itself, either position will sound 

good, but slightly different. Here is another case where a 

little experimentation is worthwhile to find what is right for 

you. This switch becomes very important, though, when the 

amp is used in conjunction with another amp in a dual amp 

setup. If the speaker in the two amps are set “out of phase” 

with each other your tone could be weakened considerably. 

So when you’re running the amp simultaneously with an-

other amp, be sure to check this switch to see if one posi-

tion or the other is giving you a better result. 

TROUBLESHOOTING

 

Your new Bad Cat amplifier is designed for many years of 

professional trouble free operation. Common sense will tell 

you that if you notice any severe abnormalities in operation 

like burning smell, smoke, etc.; you need to shut down the 

amp immediately. Always consult your Bad Cat dealer if you 

are unsure of the problems that you are dealing with; i.e., 

take your amp to where you purchased it.

 

No Power 

ICheck the power source from the wall first. Make sure the 

power cord is properly seated at both ends. If there is still 

no power, check the fuse and replace if necessary with the 

correct rating only. 

 

Weak Output Level 

 

Verify the signal output from your instrument first. Check 

guitar’s controls and that the cables are working properly. 

Also, check any effects pedals that may be connected in 

between the guitar and the amplifier.

 

Adverse Sounds-Hum, Whistle, Loss of Dynamics, 

Feedback, Howling

 

Check loudspeaker cones, frayed guitar cables, controls on 

your instrument, the guitar’s pickups and any other devices 

that many be connected to your amplifier such as effects 

pedals or rack processors. Some of these devices are “am-

plifiers” in their own right with gain and boosted volume 

levels and they may cause hissing and unwanted  feedback 

if set too high in front of the amp. Shut down the amp and 

check the tubes. Wait for the amp to cool down. Remove 

the back panel of the amplifier. Avoid handling hot tubes 

as they can cause severe burns. Check the larger output 

power tubes first by carefully removing the tube shields 

or loosening the clamps, and then unseat the tubes from 

their sockets but note from which sockets you removed the 

tubes. Inspect the integrity of the filaments in the tubes. If 

one or more of these tubes are bad, you will need to replace 

the entire set of the power tubes. If all the tubes are OK, you 

can eliminate the adverse sounds by swapping the location 

of these tubes. If this fails to fix the problem, you may need 

to replace the entire set of power tubes with a new matched 

set. Use of inferior quality (unrated) tubes may cause dam-

age to your amplifier. You should also check the preamp 

tubes, especially the first input stage tube 

(far right if you’re looking at the amp from the back). Microphonics (feedback 

noise that cannot be controlled by turning down the volume pot on you guitar) 

indicates a bad preamp tube(s). You may want to swap the position of preamp 

tubes to see if this will fix the microphonics problem. Preamp tubes can go bad 

without warning but can also last many years without any problem whatsoever. 

As you can see when handling tubes, they are sensitive, fragile and somewhat 

prone to inconsistencies. Please handle your amp with care when transporting 

it. Although your Bad Cat amp is sturdily built and designed to take years of 

rugged use, the tubes are not. It’s always a good idea to keep extra tubes (both 

preamp and output power tubes) handy, especially for performance situations. 

An overwhelming majority of minor problems on tube amps are tube-related 

and it’s just a matter of swapping one or more out to have your amp performing 

like brand new again.
