Sign in to disble this ad
I'm sure this has been covered somewhere, but I couldn't find my answer through search function. I have the Ampeg BA115, and now want to move up to a Little Mark Head and 2x10 or 4x10 cab. Is there an easy way to use my combo amp as an extension? Is there an easy way to bypass the amp in the combo, or do I need to physically remove it somehow? Any suggestions, warnings, or directions to threads would be appreciated.

Voila, & you have a multi purpose unit that can still be used for rehearsal or as an extension cabinet! |

the switch will interrupt the speaker wire when it is plugged into another amp
look for a 1/4 NC type jack http://www.smallbearelec.com/Detail.bok?no=88
it would have to be installed as an extra input jack, I normally mount these on back of amp near the speaker.. just makes it easier..
I will draw up a crappy MS Paint drawing and post it.
Hope this helps... it works great .. I mod alot of combos to do this..

as soon as you connect a speaker cable from another amp into the jack it will disconnect the speaker from the combo and allow new amp to power speaker without any harm to combo..
any more questions let me know..
it is up to you to find a location that will work well.. good luck.

but I haven't looked inside my BA115 to see... I also HATE horns, so I disconnected it...
