anyone heard anything about this?
any reviews?
or this type of mod:

Many posting on the Internet Newsgroups 'alt.guitar.amps' and 'AMPAGE' enquire about putting a tube rectifier in their silver-faced Fenders to 'soften things up'. It can sometimes be done without adding an auxiliary heater transformer (regardless of what the other 'guru' types may think), but below is a far simpler (and much better) solution.
Sag resistor works as well as tube rectifiers, with much less hassle.
Mesa Boogie used similar principles, calling their switch something like 'BOLD'/'SPONGY'. Value of the resistor depends on how solid the rest of the power supply is, and the threshold of when you want the sag to 'kick in'. A good starting point is 100-ohm/10 watt. I sometimes reduce the filter capacitor(s) value while I'm at it. Be careful not to go too low, or 'hum' will result. You then have two threshold 'levels' of sag, as well as the sloppy bottom end common to vintage amplifiers. Reissue Bassmans with reduced filtering and a 200-ohm/10 watt resistor can have more sag than Grandma's triceps!
