Dating fender super champ
I use this before buying a amp always-check all four transformers-will tell you if there has been problems along the way. On the bottom lower corner of the grill cloth was/is a 1×2 inch “JBL” plastic logo that Fender attached.
By 1968 deluxes usually left with CTS/EMINANCE speakers (Jensen had closed down) Once in awhile you can see the EIA code, CTS-starts with a #137-sometimes these are under the doughnut fender speaker label.
Around the back, there's a single 8Ω speaker output, a line out and a footswitch input.
No footswitch is included, but purchasing the requisite Fender accessory will let you remotely switch channels and turn the effects on and off.
This directory contains USENET articles Mic has saved about guitars, equipment, pickup, techniques, players, and so on.
Mic has graciously granted permission to post the stuff on the JT30 page on the off chance that it might be useful in the context of Blues Harmonica.
A single input feeds two independent, switchable channels sharing common treble and bass EQ controls and a DSP effects section.
As on the XD, the first channel simply has a volume control, while the second has volume and gain knobs, plus a 16-position rotary switch to select amp voicing.
Its in the middle of the 6 preamp tubes with the removable shields. For a black face, this transformer would have been made in 1964 during the 23 week (—423) The trick to this is they don’t renumber the decades.
Over on channel 2, the Super Champ X2's amp voicing selector greatly expands the combo's tonal palette.
By altering coloration, compression and overdrive characteristics, the various voicings do a good job of imitating a range of classic amps.
You’ll find 2 rows of numbers, top set is the Fender part #, always starts with a 022, in this case it would be 022921. Works as follows, they have 6 numbers, first three is the EIA manufacturer, ignore this. A silverface made on the 23rd week of 1974 will have the same date code.
The only good thing about dating amps this way is Fender never deviated-still valid today. If your JBL says D120F on it(look for the “f”) certainly could have been stock.
