I am building an extension cabinet to use with my guitar amplifier. I am using two speakers wired in parallel is this the proper jack for me to use?
Asked by Anonymous on November 28th, 2022.
This can function in the described application, but if you are simply wiring both speakers in parallel to a single jack and no switching functions are required, the W-SC-11 may be a more ideal candidate.
Product Reviews
These are the best shunned tip jacks out there. Could not be more pleased with the speed at which AmplifiedParts gets my orders out to me.
