bassituation Posted August 23, 2014 Share Posted August 23, 2014 Hi, I picked up a decent one of these recently off ebay, thinking I could use it with an extension cab for pubs. But when I plug my extension cab in it seems to disconnect the main 12" speaker in the combo in favour of the extension cab? Bit disappointing really, is this how extension cabs usually work with combos, they cut out the main speaker? I can't find a manual or much info. Thanks.

gary mac Posted August 23, 2014 Share Posted August 23, 2014 That didn't happen with the Trace combo I had. The idea is that when the extra cab is connected you will be able to deliver the max wattage. Quote Link to comment Share on other sites More sharing options...
bassituation Posted August 23, 2014 Author Share Posted August 23, 2014 Thanks Gary, that's what I thought, but when I put my ear to the main 12" with the extension connected there's zip coming out of it, then when I disconnect the extension, it's back to it's normal sound. Odd. Quote Link to comment Share on other sites More sharing options...
JPJ Posted August 29, 2014 Share Posted August 29, 2014 Somebody may have changed the speaker (from 8 ohm to 4ohm) to get the full output without an extension cab and if they did, they've also gone on to do a cracking mod to the extension speaker socket to ensure you can't plug in an extension cab and inadvertently present too low a speaker load to the amp.
