 OPTIONS TO BE ADDED TO YOUR PURCHASE

 

OPTIONAL ON-BOARD ATTENUATOR FOR STUDIO/RECORDING/LOWER VOLUME

On-Board, 6DB Attenuator (will be matched to speaker impedance)

This option can be added to any model: $175.00 for 6DB.

 

A brand new feature is now available for all production models that are intended to be used for recording and/or studio amps.  This option can be added to any amp model.  This is our switchable, on-board Power Attenuator.  This feature enables the amp's tone and volume controls to be set at just the right place to enter the "zone" while allowing the switching of a 6db Power Attenuator, thereby having the effect of reducing overall volume by up to 75% (-6db).  By activating a toggle switch, overall volume can be cut to about one quarter of stock power without having any affect whatsoever on the amp's tone. This is a highly sought after feature and makes all three models perfect for studio recording as well as playing in smaller venues without compromising one drop of tone.  This special feature adds enormous versatility to a line of amplifiers that are "dripping with tone".   

  Add Attenuator

"LINE-OUT" OPTION FOR RECORDING AND HOUSE PANELS

Line-Out Jack for direct connections to panel or other amp

This option can be added to any model: $50.00.

 

Many musicians "mic" their amps so they can capture the true tone and use a house panel or recording devisce. This option can be added to any amp model. Most amps have the ability to have a "Line-Out" circuit added to the external speaker jack or to the chassis, if you prefer.  If only one speaker jack exists, we can typically install an additional jack to accommodate the "Line-Out" feature.   A "Line-Out" jack can also be used to feed your amp into another amplifier.  This option is included in all PROFESSIONAL versions of our amplifiers.

DUAL CHANNEL REVERB AND TREMOLO

"CHANNEL BRIDGING OPTION"

 

Reverb and Tremolo for Channel #1 and Channel #2

"Channel Bridging" capability included.

This option will work on any amp that normally has two channels

with Reverb and Tremolo on Channel #2: $125.00.

 

This option adds Reverb and Tremolo to Channel #1 (Dual Channel Reverb/Tremolo).  Most importantly, it puts both channels in Phase with each other.  This allows "Bassman/Marshall Channel Bridging".  This is where a jumper cord is plugged into Input #1 of channel #1 and input #2 on channel #2.  Your guitar is plugged into input #1 on channel #2.  You can now use channel #1 to mix with channel #2 which thickens and fattens up your tone.  There is also no loss in volume if you decide to plug two guitars into your amp since both channels are now "in phase" with each other.  This option can be added with Marshall Voicing which makes for a really nice tonal combination.  This option is included on all PROFESSIONAL versions of our amplifiers. 

  

Add Dual Reverb/Tremolo
 

 

MARSHALL VOICING FOR CHANNEL #1

 

Marshal Voicing on Channel #1 for Two Channel Amplifiers

This option can be added to the DL2212(SE) Deluxe Reverb and VB3512(SE) Vibrolux Reverb:  $50.00.

 

Marshall Voicing can be added to any 2-Channel amplifier.  This include any AB763 circuit amp such as the Deluxe Reverb, Vibroverb, Vibrolux, Twin Reverb, Super Reverb an many others.  With this option, the first preamp is voiced with the same value components as the majority of Marshall amps.  This greatly increases the mids and punches them up for leads.  This option works well with an A/B switch.

Add Marshall Voicing

 

CLASS-A/B TO CLASS-A OPERATION

 

Cathode-Bias Circuit and Toggle Switch (emulates Class-A Operation)

Please call us before adding this option.  It will not work on every model:  $175.00

 

This option changes the way the power amps are biased and duplicates the Vox Class-A configuration so the power tubes are self biased to operate in Class-A mode. This greatly enhances finger responsiveness, but also reduces the overall output of your amplifier.  With the toggle switch, you amp can be switched between Class A/B and Class A operation.  This option is not recommend for every model.

   Add Cathode Biasing

 

 

FX LOOP - BUFFERED WITH GAIN CONTROL(S)

 

FX Loop, Series; Buffered Loop

This option can be added to most Blackface amps (Deluxe, Super, Vibrolux, Princeton, Vibroverb, Twin, etc.)

This loop included "mini-pot" to adjust the gain in the SEND and RETURN jacks:  $350.00

 

This is a super quiet, buffered and amplified "series" FX Loop.  A 16DB (total gain) buffer will be added to your amp with a net gain of 6dbs. Our Buffer includes mini-pots inside of each jack so SEND and RETURN signals can be adjusted with a small screwdrived.  There is also a toggle switch that enables the buffer to be completely bypassed.  Loops will be pre-set at "Unity Gain" and will work with most pedals.   FX Loops can introduce some noise into the signal path so they must be used with the shortest cables possible.  (They will not work well with two, 25' cables running to and from your pedals).  We include this loop on all PROFESSIONAL models of our amplifiers.

Add FX Loop


 

HALF POWER SWITCHING

 

Half-Power Switch (Can only be installed with 4 output tubes)

This option will work on any amp with four output tubes.  $50.00

 

This option works with any amp that has four power output tubes.  It removes two of the tubes from the circuit by lifting the cathodes above ground.  This reduces output power by 50%.  The Twin Reverb, for example, is a great amp to have this option.  Marshall heads rated at 100 watts will also work well with this option. 

 

Add Haf Power Switch

 

OPTIONAL CEASAR DIAZ-STEVIE RAY VAUGHAN TREMOLO CIRCUIT

SRV has the famous "Amp Doctor" Caesar Dias design a feature where the tremolo could be removed from the signal path adding back lost gain used by the tremolo circuit.  As part of our Special Feature series, we add this feature to all Blackface amp with the AB763 circuit design.  There is no additional cost since this feature is included as one of the options in a Special Series amp.  If you order a "Special Edition" version, this option is included at no additional cost.

A NOTE on CIRCUIT DESIGN

 

Three of the most popular "Blackface" era amps from the early 60's have been selected.  They are the PR, DR, and VB series.  Designs are loosely based upon the original "classic" schematics of the Fender® Princeton Reverb®, Deluxe Reverb®, and Vibrolux Reverb® amps.  We use only the finest parts such as Mallory M-150 and Orange Drop and Silver-Mica capacitors in the tone stacks, CTS potentiometer, Carling switches, and other top quality components.  Wherever possible, component and wiring layouts are similar to the original designs.  We have enhanced many of the wiring runs and component selection in areas where we find noise and hum may have been introduced.  We believe we have effectively turned back the clock by over 40-years with the production of these hand wired, boutique style originals that produce the sparkling tones that resulted in Blackface amps being so highly coveted.  (Note: Standard models are based on the same circuit designs and are built with basic components.)

 

A WORD on BIAS SETTINGS

A properly set bias is similar to the setting of the idle of a your car engine.  Just like the engine, there is an ideal range that makes your amp come "alive" and a range that just won't work.  At FireBelly Amps we set the bias for an optimal balance between clean headroom and compression.  We bias the Output Tubes at approximately 70% of their maximum plate dissipation ratings.  This is an ideal setting for most applications and does not overly stress the output tubes.  The correct bias setting will help your amp sound its best and find its perfect "sweet spot".

A Note on our CABINETS

Our cabs are constructed of  solid 3/4" finger jointed pine for overall strength and articulated tonal quality.  Best of all, our cabinets are built in the Ted Weber cabinet shop in the U.S.A.!  FireBelly Amps wishes to honor Ted Weber who was a man whose vision provided high quality cabinets and speakers.
