FENDER BLUES JR. MODS. We are often ask if we can do mods to blues junior amps and yes we do. There are many mods for this amp, we can do them all or just some, we can install new output transformers or speakers or just do the electronics.

MODS INCLUDE:

Tube Replacement. We have a selection of EL84 and 12ax7's for getting the best tone out of this amp but to do so you might like to do the following.. Output Transformer Replacement. We replace the standard undersized Blues Jr. Output transformer with a larger Hammond Output transformer or one of our hand wound transformers for better tighter bass, cleaner headroom and more clarity. Tone Stack Mod. Produces Twin-like clean tone and clarity. Changes the caps in the tone stack to the original values and reconfigures the Mid pot wiring. Presence Control. The presence control lets you adjust presence from a brighter, louder aggressive tone to a more laid-back sound that’s ideal for jazz or a warm, mellow tone. Sparkle Control. Operates much like a tweed-era tone control, rolling off the harsh highs gently across a spectrum that covers the treble and the upper mids. Coupling Cap Values Mod. Early stage cap values are changes for thicker tone and more bass. Adjustable Bias Mod. For setting power tube bias for best headroom or early tube break up. Replacement Speaker. A Celestion Greenback works well with this amp but any other could be used for desired tone. Cap Job. Replace all the signal path caps with Polypropylene "Orange Drop" caps and Silver Mica for clarity or SoZo for vintage tone. SwitchCraft Input Socket. Get rid of the standard plastic socket and install a heavy duty metal socket. Standby Switch. Extend tube life by turning off the high voltages on the tubes during playing breaks. Hum Reduction. We can sort out the amps hum and buzzing if you have these problems. Reverb Problems. We can sort out problems that you have with the reverb of this amp. Cheek out the testimonials on these Blues Jr. amp mods. Please email us and we can work out a price for the mods you want done. Want something better? Handmade? Point to point wired?

FENDER DELUXE REVERB AMP RE-ISSUE MODS

Cap Job for Re-Issue Amps. We can replace all the signal path caps In Re-issue Fender amps with SoZo caps for authentic vintage tone. Can be done on any amp fitted with standard caps to improve the amps tone. SoZo caps are current day replicas of the original "Mustard" caps found in old Marshall's and other vintage amps.

MIDI CONTROLLED CHANNEL SWITCHING FOR AMPS.
When installed into a 2 or 3 channel amp and used with a multi effects processor and a MIDI foot controller, your tap dancing days will be over. Without MIDI control in your amp, you would need to hit 2 buttons, one for the amp and one on the foot controller for the effects unit to get your sound. With the MIDI Mod installed in to your amp, or setup separately in its own box plugged into the amp, it will change the channels on your amp when you change patches on your effects unit, so you only hit one button on the controller to get all your sounds. And the channel changing can also be programmed like your effects unit can be. If installed into your amp, you will have a midi in socket and a small program button. Your existing channel switching operation will not alter, but now you will use this to program your amp to change channels when you access you sounds from your effects unit. The amps channel changing can still be operated as it was before the Midi Mod was installed. Top pic: Midi Mod kit and the bottom pic: Midi Mod kit installed into a Peavey 5150 head. This Installation controls the channels, effects loop and an added boost volume for the lead channel.
