    I own one of these that I bought from S.I.R. Los Angeles back in about 1979. The manager at the time showed me the rental logs for the amp and EVERYONE had rented it at one point, including Beck, Bo Diddley, Muddy Waters, etc. Pretty much everyone except for Clapton and Page. I’m not even a guitar player (I’m a reformed drummer) but I had to have it – right then, that day. It matches up nicely with the Jazzmaster that The Ventures gave me the day I left the band after two years as FOH/Road Manager. That particular Jazzmaster is the guitar they recorded “Walk Don’t Run ’64” with.

    I bought a 62 brown Pro a couple of years ago on ebay and it is near mint. Just the filter caps were replaced. I did some upgrading on them. They were cheap Chinese caps and didn’t do a good job of filtering and they were new. I put in some Sprague Atoms beefing up the mains to 100 uf and it just roars. I took out the Oxford 15M and set it aside. Wasn’t a great sound but held up to the 40+ watts alright. I wanted a big beefier sound with a high decibel(SPL) rating. Not a lot of choices but Eminence has a few. The 150 watt Legend and a 75 watt version they used in the Vibroverb reissues. The 75 sounds a little better.Eminence also makes the Big Ben in the Patriot series with a british tone and can handle 225 watts.It also sounds nice. All three speakers have over 101db rating and are frickin loud! I also run it through a 2-12 Marshall cab with the G12H-30 pulsonic cone Celestion greenback speakers. Now were talking tone. I have a picture of Chuck Berry in the early sixties playing his Gibson ES-350 and behind him is a 62 Fender Pro with the wheat grill and doing his “duck walk”.He’s plugged straight in to the amp and sounding great I’ll bet.My amp looks just like it.Hung it in my guitar room.It sounds great with my Strat but just sounds pissed off with my Paul Reed Smith and its hot humbuckers…Mark K.

    I have a transition model ’63. Tube chart says LC, but it is a brown face, flat logo on a silver grill cloth and black tolex. Came with a JBL D130-f. I visited a steel players site and they subject of the transition models came up. Seems it was a limited run, or until Leo used up the old stock. Great chimey sound and tremolo. I used a 65 Fender Reverb unit with it. Killer tone with my Telecaster.
    I traded for it to use with a Vox Continental but Dual Showman sounds better with the keys. Anyone else heard of the transition model ’63?

      I stand corrected! After disassembling the amp, I found a few hidden clues that this was a pretty good retolex, but not one of the transition models. I have since shipped the cab to MOJOTONE for a complete rehab of the cab and tolex and grillcloth like what came on the amp. The JBL checked out at the speaker shop, and the amp will undergo a complete check to make sure there are no issues with authenticity.

        Mojotone has shipped the cab. My tech has gone over the amp. She’s all original, except the power transformer, which is a ’65. I’m currently looking for an early 62 or mid to late 61. Rough brown tolex with Oxblood grillcloth with gold weave. Too cool!

    When I was in high school in 1973 I acquired a brown Fender Pro in a trade, identical to the one pictured. In my ignorance I traded it away for god knows what POS. At the time the browns were considered just used amps and certainly not yet vintage, collectible or even desirable. Heck they didn’t even have reverb! Everyone wanted Marshalls or at least a modern Fender black or silver face. I weep to think of the one that got away, especially when I see them selling for $2500+.
