Of course there are accepted mods (or ‘upgrades’) that are absolutely not going to ruin the vintage value of your Bassman head.Changing to a 3-prong AC cord is pretty much an expected upgrade or mod, as is replacing the filter capacitors.Therefore, we want to modify the chassis as little as humanly possible, and save the replaced resistors and capacitors in a little baggie.Should you decide to fleece some other sucker via e Bay with your ‘original’ Bassman head, it’s easier to do if the ‘old’ parts are still around.
Out of the box the silverfaces and blackfaces will fit many occasions and are therefore not widely discussed in terms of serious mods like, for instance, the Princeton Reverb.I recently purchased a 1972 Silverface Champ for 40 bucks.I am not an expert on amps, Fender amps, or Silverface Fender amps. I am merely someone that loves old gear, appreciates Silverface amps, loves to write, and loves history.Still, it’s not just the tubes that provide the desired distortion in tube amps.There are also the other critical components that tube amps require, which transistor amps don’t have.When striking a chord on your guitar, the whole value chain of electrical components must quickly transport a large amount of energy (current) to the loudspeakers.Tube amps usually have a slower response time than transistor amps.The Vibrolux is quite similar to the Pro Reverb 2×12″ except for the smaller speakers, output transformer and power transformer. 10″s provide a more scooped, responsive, punchy and sparkling sound than 12 inch speakers.The 12″s are fuller, warmer, looser in the low end while having more mids and a more three-dimensional tonal spread.That Music Master Bass amp or Silverface Champ that you could have bought all day for 50 bucks as recently as 2 years ago can run as high as 350-400 on ebay now.Though, hopefully no one will bid on those that are that high. But, they are still available at killer prices, if for no other reason, there are many of them still available..a silverfaced amp was passed over in the 80's and 90's by someone that HAD to have a tweed or blackfaced one.by Frank Stroupe ***WARNING-There are voltages inside of a tube guitar amp that can KILL you.There are components in the amp that hold live current long after the amplifier is unplugged.So, here I am, writing about the history of some old gear, the Silverface Fender.
