Comments: Pro Tube Series/Pro Reverb amp. Fender did it a disservice to call it a “Pro Reverb”. It is so different from the blackface and silverface Pro Reverbs that it really doesn’t fit the description, but it is a wonderful amp. On the clean channel at the 12.5 watt setting and with the bright switch clicked in it sounds so much like a Deluxe Reverb that I doubt it you could tell the difference. And the gain channel has a very pleasant, warm presence (not a harsh gain like other Fender amps (Prosonic) seem to have). These were quickly discontinued so there seems to be very few of them out there. – Dave Underwood

    Love Mine – great for home and Studio – I add a JBL D130 (original) in an early Bandmaster sized 2-12″ enclosure 10X20X30 closed back with a cross over to a hi-freq driver installed in it and the combo does superb with my Pedal Steel, Lap Steels and Guitars.  Would consider owning a backup.

    I have one and gig with it. This amp really got a bad rap. It is not a living room amp. It needs to be played at live-gig volumes so the power tubes are put to work. It doesn’t sound good until its really pushed; you need the room size and air-volume for this amp to really come into its own. It actually sounds like crap in my living room–a definite Jeckel & Hyde thing going on.

    The clean channel sounds great–nice and chimey, a classic Fender sound. Overdrive channel is nice on a Fender amp; I re-tubed the gain stage with a 5751 and it really gave the channel more clarity and definition. Like all tube amps, you can really fine-tune the tone with a retube. Fender isn’t a tube manufacturer and they go to the same marketplace to tube their amps.

    On the “con” side–it is heavy. I hate lugging it around. Also, tube changes are difficult due to the layout of the chassis and the fact that the tube sockets are attached directly to the circuit board under the chassis deck.
    Also, at 1/4 power, the tremolo circuit is under-powered and is barely noticable.

    All in all, this is a great gig gin amp.

    Terrific amp very classic fender chimey sound thang going on here just picked one up for £650 and really happy with it but it definitely needs to be played at gigging volume …..if you want a boudoir amp buy a champ! The stock speaker (Jensen)was a bit shrill on the highs so I swapped it out for a Weber ..good call this is now a different amp night and day

    Im considering a pro now, Im currently using a concert rivera model from the 80’s, a real sweet amp tho Im not overly fond of the low volume sound. its gets real sweet and compressed when your pushing it. I imagine the pro is a lot like that but have not gigged with it. I do like the reverb and vibrato combo on this amp. it will be nice to have one amp with all my fav things which is reverb, vibrato,and pedal 2
    channel switching. maybe my concert and champ will finally be retired after about 20 years or so of use.

    I have this amp and the reverb is making a lot of noise. I want to change the 2 tubes for the reverb/vibrato but I don’t know which ones they are. Can you help?

      The reverb driver is a 12AT7. On the tube chart inside your amp its number V7. All other preamp tubes on this amp are 12AX7’s so it’s not tough to find it.

    I have a 2002 pro reverb reissue. I think this is a great amp. It’s a beast of an amp to carry around but aside from that, it’s a great amp. I’m having a problem with it now and it has me scratching my head. I was using the amp a couple of weeks ago and all of a sudden….no output! I took out the tubes and had them tested. One was completely gone and two more were weak. I replaced the three of them. They were 3 of the 12AX7’s. I thought for sure that I had the problem solved. Brought the tubes home, installed them….same issue was present.
    I say that there’s no output but I think it’s more of an input problem. When I tap on the tubes, I can hear the taping noise coming through the speaker. Also when I flick the output switch to full, I can hear a small hiss in the speaker get louder.
    Any suggestions as to what the problem might be would be greatly appreciated!

    I bought mine new in 05. I just use the clean channel and use a pedal for the OD

    the cleans are fat snappy and warm with clear definition. Plenty of power even at the 12 watt setting which I use most of the time. I use it in the studio as well a bar and out door festival gigs. When im out doors I put it to full volume.

    the reverb is noisy when its above 4 and hums quite badly at 7 or 8 to the point its gets unusable.

    I only use the verb a 1 or 2 so I have no issues.. From what I read on the net theres an inherit problem with the verb circuit. No tech I found was able to correct it but you can tame it with a lower power tube in the verb socket.

    its a great amp very heavy but the tone out weighs any negatives.

    the head it improves with a speaker change but im still using the stock Jensen and I have no need to change anything.

    little know fact is you can use the loop button as a clean boost and use the setting on the back to dial in the amount of boost

    another plus plus is it has external bias and balance pots so tube change take 10 minutes and I can do them by self
