Guitar Amp Modifications and
Tweaking
Would you like to have your
silverface Fender
converted to Blackface specification? Click here for more info.
Fender Blackfacing
How about a better bias adjustment circuit for
improved tone and longer power tube life for your silverface Fender amp? This is included in the "blackfacing"
conversion or can be done to many other amps.
Would you like to get rid of that "ticking" sound
in your vintage Fender vibrato circuit? $15
Would you like more intense Tremolo
in you Princeton Reverb. Then can be done without changing the character
of the effect. $15
We can add spring reverb to your
Fender Deluxe, Bandmaster, Concert or Showman. You'll have to give up the
vibrato function and the "Normal" channel that you probably never use anyway.
The new reverb circuit will feature bass and treble controls. Cost is
around $225 to $265 depending on whether you want it to be footswitchable or
not. Note: there is not enough room in the head cabinets to add the tank
without excess humming so you'll have to find a bigger cabinet or mount the tank
outboard of the head cabinet.
Would you like to have
previous modifications removed to put your amp back in stock condition?
Do you want more gain, more
treble, less treble, more bass, less distortion, more distortion, more “sparkle”?
Other available mods available
for many but not all amps;
Reverb on the "normal" channel.
We can convert many solid
state rectified amps to tube rectified or tube rectified to solid state
rectification. This changes the dynamics and headroom of the amp.
Triode/Pentode Switch (1/2 power
switch)- This allows
to you reduce your output power level to about 1/2 of normal. This usually
means a reductions 20-30% in output volume and a slight loss in treble response.
Price ranges from $65-$150 depending on amp model but is $80 for most amps.
Post phase inverter master volume
control - This allows variable output volume while keeping your preamp gain
turned up for a "cranked up" sound at lower volume. Price
from $65 and up depending on amp model. $75 for most amps.
Ever wish your Fender Deluxe Reverb
had more volume and headroom?
Bring in a Blackface or Silverface Fender Twin Reverb and let us convert it to a
"Super Deluxe Reverb". Price: $575 This
includes the following:
Replace both transformers
Install 4 new 6V6 output tubes.
Install octal tube socket for tube rectifier
New GZ34 Rectifier tube
Re-locate transformers, choke and bias pot
All new power supply and bias supply capacitors
(Sprague Atom)
Several circuit changes as necessary
These and other modifications may be available
depending on amp make and model.
