Bassman Reissue question
Does the Bassman Reissue that was made before the LTD have a printed circuit board? Also out of what material and construction method for the joints is the cabinet made? I know the LTD is a pine cabinet with finger joints.
Thanks,
Jon
The Bassman RI (circa 1990's) was made with a printed circuit board and had a solid state rectifier which was changeable for a tube/valve rectifier. The cabinet was made from marine quality plywood.
The Bassman LTD has a pine finger jointed cabinet and is far closer in specification to an original '59 Bassman, although it still has a printed circuit board. Either one of the reissues make great harp amps with a few minor tube swaps..
Hello Jon- Looks like you got some good answers from the guys on this one! The Fender Bassman amps are printed circuitboard, but one of the main reasons I don't hate them is that the tube sockets and jacks are chassis-mounted. This makes them MUCH sturdier and easier to repair than amps that mount everything on the printed circuitboard!

Hi Skip. I have been seperated from my 59 BMRI for quite awhile (long story). It will be back in my loving arms soon and in need of a retube. I had been running the original Groove Tubes and was happy enough with the tone for guitar. Does the amp need to be biased if I change the SS rectifier to a tube rectifier? Thanks.
Hello Johnny- Thanks for writing. First, are you sure you need all new tubes? I doubt it. If you are setting it up for harp, I'd try some lower-gain preamp tubes, but the power tubes may be just fine. I would also say that checking the bias when changing to a tube rectifier would be good, but not essential. Some harp guys like the solidstate rectifier, especially outdoors.... give it a try.

Give the 5U4 rectifier a try, it's a nice change for the Bassman.
I have a question on my 2004 Ltd Reissue as well - I just changed out the stock tubes for three matched Baldwin 12AU7's across the board. Its certainly closer to the vintage sound that I desire, but not close enough. My question is - do vintage tubes help the cause in an amp that is so modern? I see these tubes selling for 5 times what I spent, but the gain is the same and the design is the same (I think) ...........can you hear a difference?
Hello SacTown- Thanks for writing. In general, new tubes are not as consistent or reliable as old tubes. The tonal differences between vintage and new-production tubes can be very subtle, but an experienced ear can usually hear a difference between say, your old 12AU7s and a new JJ version.
The more important concern with your RI Bassman is substituting lower-gain tubes (12AU7s or 12AY7s) for higher-gain tubes (12AX7s). This has a dramatic effect on both gain, volume, and tone. I would suggest a 12AY7 or 12AT7 in the middle position. Having a 12AU7 in that position makes the tone controls less responsive.
I don't think that vintage Jensen P-10R speakers would be a realistic option for most people to consider. $800 is not an unusual price to pay for a set of four.....! The RI Bassman is a modern classic. An awful lot of pros and semi-pros have used them for years. In my opinion, the only mods to consider are tubes. If I wanted to try some different speakers, I would consider ceramic magnets for more bass, but the stock Eminence Alnico speakers are fine for all but very high-volume players.

Jon, I had one of these a while back, and if I remember correctly, it had a PC board. The cabinet was still pine finger jointed. I still have my original '59 Bassman 5F6A. I had some trouble with it years ago and that is why I bought the 1990 reissue. Once I got the '59 back on it's feet, though, I dumped the reissue off on a friend.
An important lesson learned: Don't set drinks on a vintage amp (even though you'll see drink rings on most of them).
