    Wow! just got back from playing a festival. Usually I'd bring my 2x10, but
    thought why lug it. I know the sound guys and figured small amp would be
    plenty. I've been liking the way the Pro Jr turned out and it was a pleasure
    roaring through it today~and the guys also thought it sounded great:)

    Harp went through Masco and 4x8 cab, backline bass amp was an SVT, and drums
    were fully miced. Set my vol on 6 1/2 tone 4 1/2. Guess good sound sound guys and
    a little amp is all you need!

    I had my Budda get a hum (bad cord) and had to go to my old original series PJ for the night-same experience you had-massive tone and a great night! I gigged it for years and often sound guys would stick a mike on it when first seeing it-and most of the time after the show would admit it never got turned on! I tend to set mine at 10 or so and tone at 6 or 7 and use guitar to control it.

    1st: I doubled up the 1st filter cap and cut NFB wire.
    2nd: I cooled the bias and replaced 01 coupling cap with 05.
    All good mods~but the final trick was building a new cab and
    fitting it with 12" spkr tried a few and wgs ET65 did the trick!

    I've played it unmiced at practice and jams sure easy to haul
    around~only 26lbs! But miced up outdoors~perhaps I've got
    a new favorite...

    At some point I'm gonna change out all the filter caps...
    That should get rid of any extraneous noise the amp
    still has.

    I've had two PJ's and I sold my last one when I bought a Vox AC10.

    I sure miss that PJ.

    Great info. Thanks.

    How large was the venue? I just posted on Glowing Bottle subforum about this. I'm happy to mic it but I'd love to hear more about your experience.

    For instance, what kind of music do you play? How much headroom do you need? Any pedals? How loud was your drummer?

    Thanks!

    Hey birv2~ It was huge outdoor event with folks out on the
    ski slopes. We were playing hillbilly boogie/swing type stuff.
    Great sound guys doing the festival, everything miced including
    drums so it was loud, but with monitors it was perf. My Pro Jr.
    and harp players cab had SM57 mics close and off axis. I had a
    TS10 that I used on a few solos mostly slide stuff just to push
    it over the edge~otherwise I get gritty enough just digging in:)

    The sound guys thought my guitar sounded clean and clear...
    Power trio before us the guitarist was going into a 4x0 bassman
    w/several pedals and is a loud player! Perhaps by comparison I
    was clean and clear. I'd use the Pro Jr again even without the
    sound guys. Unmiced it has certainly held it's own at some loud
    jams~

    hope that gives some info~

    Thanks for the reply! Much appreciated.....

    So if your sound was clean and clear, I'm assuming you didn't have the amp cranked. I do realize that after 7 or so on the dial you don't get more volume, just more OD. So you had your amp volume on .... and with it mic'ed, it did just fine.

    I'm semi-interested in a bigger speaker/cab, but I truthfully don't want to add any more weight. It's about as heavy as I'd like right now!

    I'm also assuming you played a tele (of course!). How hot were your pickups?

    Played Tele with CS TX Special neck and Tonerider Hot Classic bridge.
    Vol & tone abt 3/4 open mostly in middle switch position, amp set
    with vol 6 1/2 tone 4 1/2.
    Built cab out of cherry, probably doesn't weigh any more with 12"
    than stock particle board and 10".

    Great sounding little amp but needs a few mods and a bigger and better cab. it's low end mdf stuff and the 10" sounds congested. My new cab is a larger pine cab. Weighs nothing and sounds great. Any new cab will be lighter, bro..

    Sorely tempted. I've been mulling over a new amp but what the heck, I like that Pro Jr anywhere I can play it loud enough to get it going. A new cab would be cool and pretty cheap fun to experiment with vs going down the new amp trail.

    Go for it Stubee! A little saw dust and a bit of solder...ah:)

    Not as much fun working on a PCB amp~gotta be more careful
    with the heat~but hey it can be done. Eyelet boards or terminal
    strips are a lot easier!

    I replaced the output transformer on my Pro Jr with a Mercury Magnetics product. Pushes out the presence now.
