    I have a Champ Clone with a Weber Signature 8S alnico speaker. The tubes are Genalex.
    It does well with mids and highs but lacks lows. Are there ways to mod it to get more bass response?

    Other than bigger speaker? How about a full range 8" ?

    It's a lil hard to get much more bass from that little circuit/speaker combo... As Mike said if you can get a bigger speaker that's the easiest and probably the best way.

    If your good with a soldering iron you could try changing the second coupling capacitor from the .022uf value to the good ole' Fender Deluxe value of .1uf. Might help but a bigger speaker is probably a better solution.

    Champs in a stock-sized cab with an 8-inch speaker (the only size that will fit in the stock dimensions) are inherently boxy sounding without much low end. It's the law of physics. However, an extension cab with a 12" speaker can really beef up a Champ (you can just unplug the internal speaker and use the amp like a head for the 12). Alternately, a larger custom cab that fits a 10" or 12" into which you transplant the chassis (no harm done as it's only held in the cab by a pair of bolts) is the option if you want to keep it as a combo.

    I'm always bemused by people who want 'more bass' from a Champ.

    I've owned three, 68 drip, 76 SF and the Fender EC. All of them produce a balanced tonality through the stock alnico Jensen (68), ribbed Weber Sig (76) or smooth cone Weber Sig 5F1 EC.

    When I micc'd these amps up, they sound like a big Fender. When recorded, there's numerous examples which demonstrate they sound good stock standard.

    You aren't ever going to get big amp, gigging tone out of them.

    They can be enormously improved with a proper service. There's not much power to play with so you can't afford to lose freq response.

    I have a Fender Rhodes plugged in for practice and it gets fine mid range and but no bass notes at all.

    Turn it around and face it towards the back wall....instant bass boost.

    Try running an EQ pedal after your OD box if you use one - see Wampler's YouTube video on this- was a game changer for me- much increased tonal flexibility!

    I've got a Champ clone w/ a 8" Weber Alnico Blue Pup. I get a better low end with a neck pickup with scooped mids. Without a tone circuit, you're pretty much limited to what your pickups are putting out. My Strats with CS54's lack mids, so I get good low end from those as opposed to my other Teles and Strat that have a mid-60's tone to them when I use that amp.

    There are two options I've got:
    1- Use an EQ pedal. I use a Boss GE7 with it sometimes.
    2- plug another speaker into it. All my amps are 8ohm, and from time to time I'll unplug the 12" Weber 12A125A
    from my Tweed Deluxe clone and plug that into the Champ.

    Wouldn't the WGS G8C with 18 ounce speaker get you there pretty cheaply? I'm hoping it will be as full sounding as indicated by many of the reviews I've read. I have one and had hoped to make a baffle this weekend to install in my cabinet, but didn't get it done.

    12" closed back enclosure. But may move into bass players territory.

    22uF/25V bypass cap on V1a. This will increase overall gain too, if it isn't already fitted. Similar can be done to v1b, but may not be desirable. Make them switchable?. Warning : You may end up with the bass, but it'll likely be flub. Croc clip various caps in place until you find what you like?. My Champ-a-like has no bypass caps and I find the bass to be all I could wish for. It sits so beautifully.

    Larger speaker. A 1x10", 2x10" or 1x12" cab can make a heck of a difference.

    EQ pedal. Cheap, simple, effective.

    Where do you find the bass to be missing?. A 1x8" close mic'd sounds glorious when recorded or lifted through a P.A. Perhaps less so on its own. Is this in a band context, recording or pleasure-noddling?

    Which clone is it?, is it a PCB or turret/eyelet board?
