    My vibrochamp came with an added external speaker output. I've heard on forums that the 8 inch speaker really limits the sound.
    Should I either:

    1.) just go the easy route and pop in a Weber 8 inch speaker

    OR

    2.) find a 1x10 or 1x12 cab and speaker set to 4 ohms to run it through (a lot more work and time-consuming)

    Is the extra 2 inches really worth it? Also a huge factor for me is keeping the volume low for my neighbors so it might actually be smart to keep the smaller 8 inch.

    The 8" does limit the sound, but the sound that it makes is sweet. Would be the perfect practice unit, if it only had a reverb tank. I'd leave it alone, you can hear it fine at home, and if you need something a little more gutsy for playing out, watch the funny papers for a good used PRRI, etc.

    A few considerations.

    If stock your VC is set up for a 4-ohm speaker. Those are available but less common. I would not suggest running the amp on an unmatched speaker.

    On the VC's I build I replace the RCA jack and use a 1/4" jack like the other amps use. Obviously that requires modifying the speaker cord. That gives the option to use an external cab.

    The 12" will not be louder due to size. It depends on the speaker. You will get better spread. You may even try a 2/12 or a 2/10 cabinet. 8-ohm wired in parallel will give the 4-ohms needed.

    The big improvement with these amps comes from stuffing in a bigger OT , and one with a much better sounding 8 ohm tap!
    On my second VC a 1982 reissue model that I did the OT mod to I also cut the baffle to fit a 10" driver .
    It takes a bit of doing, but it will fit, it's just that dependant on the steel frame of driver you use you may have to notch it to clear the long multi section filter that hangs down off the Chassis.

    I had a 65 Vibro Champ and ran it thru my 67 2X12 Bandmaster cab.

    You would be surprised the difference when moving more air.

    Even for low volume home use moving more air with bigger speakers sound better imo.

    I have a Champ and a VChamp, both of which have the tone of the gods when fed into one of my Marshall 4x12 cabs that I wired to 4 ohm. Very thick, airy and beautiful Class A tone and quite loud too! 5w can make a lot of noise!:cool:

    I have 1968 Vibro Champ that I modified to mount a 10 inch speaker and it is a tremendous improvement.

    you don't need to mod the amp.. just replace (and save) the rca jack and replace with a 1/4 switchcraft.. fits the same hole. Make a new speaker cord (and save the old one with the RCA amp jack) and you can run either the internal OR the external speaker for under 5$ and not drilling any holes

    Or you can make a speaker lead with a male RCA jack on one end and 1/4" mono jack on the other end. (For use with an external speaker cab)

    My Champ (non-Vibro) got a larger OT a while back, as well as a new Jensen P8R (AlNiCo) 8" speaker. Both made a big difference and together they're a huge improvement on the stock setup. I actually prefer the way it sounds through the 8" speaker compared with a 1x12 cab.

    Yes, over driving a speaker a little is a big part of a great solo / lead sound!

    Why bother.. unless you arent solder iron friendly? One more thing to forget at home or trip/disconnect

    This is the same thing I do. I like the flexibility. Grab and go when the small combo is what I need. Use it as a head when I want something else.

    There are lots of different ideas about lead tone and distortion, as evidenced by the posts in this thread. Not right or wrong just different tastes. I rarely like the distortion contributed by a speaker. But that sound is certainly what many well-known players wanted from a Champ. My favorite setup with a Champ is a 2/10 Alnico cabinet. Lots of fun options to explore.
