    I just purchased a 1970 Guild Maverick Bass Combo I'd like to use for recording and small gigs. It is an all tube 25 watt combo with a CTS 15" speaker. Problem is the speaker starts to breakup at about noon on the dial. I'm looking for a vintage year correct replacement (don't tell me some modern thing).

    The dimensions of the sealed portion of the cab where the speaker is 19" x 20" x 8". The 8 inch depth is what's throwing me, i don't think I'll be able to fit a JBL D140 or K140 in there.

    Or should I just get the thing re-coned, you think that will assist?

  2. Are you sure the speaker is actually messing up? Most tube amps start to distort between 10 and 12 o'clock on the volume knob. 25 Watts isn't going to go very loud.

    If you're sure it's the speaker, then just buy an old CTS 15 off eBay or something. They aren't expensive.

    Breaking up at noon on the dial isn't uncommon at all for a whole lot of tube amps. Unless the speaker has coil rub or tears in it or something, that may be just how it is.

    Re-cone is the only way to go to keep it authentic.

    thanks guys, it gets plenty loud at noon, and depending on how i adjust the tone control and bass and treble i can get more headroom if i don't have thunderous bass.

    i guess my only question now is how do you know if you need a speaker re-coned? there's no tears and it looks fine, but after 40+ years would it be fatigued? or is that just a myth
