Unleash the tone of your Pro Jr with the Supreme Mod Kit from Fromel Electronics!
The Fender Pro Jr is a great value and a good sounding little amp, and with a little help can be a GREAT little amp. These
mods will make your amp more reliable, have less noise and better tone.
If you want a total tonal transformation, this is the mod kit for you,
it replaces every cap and resistor in the signal path with Nichicon and
WIMA caps for higher value caps, MLCC's for smaller value caps
and 1% 1/2 Watt metal film resistors for Low Noise and precision
performance.
Additionally, the recap kit upgrades every tone-critical electrolytic
cap in the circuit with high quality F&T and Nichicon electrolytic
caps. All the capacitors in this kit were specially chosen for great
tone, reliability, and accurate fit in your Pro Jr.
Please Note:The Supreme Mod kit includes both the "Complete Mod Kit"
and "Recap Kit" that we offer and is the ultimate tonal upgrade for your
own amplifier! Included in the kit is all the components necessary
to to get your amp in top shape and the detailed instructions to make
the changes easy. If you have a basic understanding of
electronics and soldering skills you can do these mods in a couple of
hours. Included in this kit are the following upgrades:
Tone Stack - Replace the wimpy Bass and
Mid caps with high quality caps with corrected values to open up the
tone and get rid of that boxy sound. What about the Treble cap, replace
the ceramic cap with a high quality MLCC cap. The adjusted value
shifts the mids up very slightly, the result is an amp that sounds huge
and warm, not boxy and thin.
Power Stiffening - Doubles the
capacitance in the first filter stage, this reduces hum and increases
reserve power for solid bass and strong picking, This mod gives the amp
the extra torque it needs to push through strong when you are playing
hard.
Cooler Bias - You are
cooking the output tubes in your amp. This mod lets the amp run cooler
without sacrificing tone or drilling holes in your PCB. Your tubes
should live a long and happy life after this mod. I include a new bias
resistor that sets the idle on the tubes to about 8.5w which is right
where it should be.
Switchcraft Input Jack - Your input jack
is soldered directly to the circuit board, apply some tension when the
amp is plugged in and you could cause major damage to the circuit board
in the amp. This mod gets rid of the wimpy plastic input jack and
replaces it with a high quality metal Switchcraft jack that is panel
mounted and NOT directly soldered to the circuit board. Included is a
shoulder washer and isolation washer so the input jack does not ground
directly to the chassis and prevents ground loops. The jack comes with
high quality color coded leads for easy installation.
Proper Lead Dress - Take a look inside a
boutique tube amp and you will see all the wires carefully twisted and
placed for greatest reduction in oscillation and noise. The Pro Jr has
all the internal wires zip tied together. I give clear instructions on
dressing the leads inside the amp for optimal performance, this results
in lower noise and less chance for oscillation.
WARNING: Performing these modifications
WILL void the warranty on your amplifier. Working on amps can be deadly
if you do not take proper precautions. Follow these instructions very
carefully. If you are at all unsure of your ability to perform these
modifications STOP and take your amp to a professional to be modified.
You can also send your amp to me for modification.
No Warranty: This kit and
the instructions included do not include any warranty of any kind. The
modifications to your amplifier are at your own risk and you agree to
completely hold harmless the seller of this kit against any and all
