    Prosonic discontinued in 2002. Several models were made in the Custom shop before assembly line mass production.

    You know you have a Custom Shop Prosonic if it has four things.
    It will say “Fender Musical instruments” under the jewel lamp.It might say “Fender Custom Amp Shop” on the tube diagram inside the amp.The serial number that starts with LO instead of CR. It has a green jewel light (not a red one).

      I know this is a late reply, but just read this post today (5/20/16) and wanted to note the differences in my Prosonic amps.
      I have one in the red snakeskin that has an “LO” serial number, “Fender Amp Custom Shop” on the tube chart label, and “Professional Tube Amplifier” on the front plate under the light jewel.
      I have a seafoam green one that has an “LO” serial number, “Fender Amp Custom Shop” on the tube chart label, and “Fender Musical Instruments” on the front panel under the light jewel.
      I have a black tolex one that has a “CR” serial number, no mention of Custom Shop on the tube chart label, and “Professional Tube Amplifier” on the front plate under the light jewel.
      Just found that interesting that none of the three of them matched with respect to those parameters.
      In side-by-side comparisons of my 3 amps, all using matched Groove Tubes in power section and Groove Tube pre-amp section, (subjective to variances introduced by tube age, etc), they sound almost exactly alike at the A and AB rectifier settings. However, on the SS rectifier setting, both the ones with the Custom Shop indicated on the tube chart label sound ever so slight smoother than the black tolex one that does NOT have the Custom Shop indicated on the tube chart label. Note again that both the “custom shop” labled ones have different serial number/factory/faceplate designations.
      Just observations to share and digest.
      Having said all of that, I like my Prosonics better than any amp I have ever owned, played, or heard. I own approx 25 Fender, Ampeg, Univox, Gretch, Marshall, etc. amps, and for my likes, nothing matches a Prosonic.
      As much of a “Prosonic Fan” I am, I have found my recent attention stuck on my new Fender Super Champ X2. What a fun little amp!!

    Just to set the record straight, the Prosonic was designed by Bruce Zinky of the Custom Shop, but none of these amps were actually built there, nor were they sold as Custom Shop amps. The “LO” prefix to the serial number indicates that the amp was made at the old Sunn Amp factory in Lake Oswego, OR. Late, production was moved to Corona, and those amps are indicated by the prefix “CR.” The Lake Oswego amps are supposed to have better-quality components than the later models, though. Fender is said to have made modifications to Zinky’s original design, but with a few circuit and tube mods, these amps go from good to really great!

      Mine is loudest when the rectifier switch in back is on number 1 labeled “Tube” and quietest when switched to 3 labeled S.S. AB2. Isn’t that backwards from what it is supposed to be? In the 2 middle position it is mid loudest too.

    These amps are sensational, especially the early “LO” series. Highly underrated and highly desirable IMO. The gain channel is amazing with cascading gain and compression. The clean channel is more like an AC30 sound, a little darker than traditional fender clean channels. These amps are becoming rarer and collectable as the word gets out.
    If you can get a red snakeskin or sea foam green custom shop model, (only 500 made) go for it, you will not be disappointed.

    My friend just purchased a sea foam green lizard skin amp. The backplates that protect the tubes are missing. Is there somewhere I could get replacements manufactured or ordered?
