I'm in the process of saving up for a used GK MB115 combo, which I will be using along with the MB115 I already have. I wanted to make a custom built cable to connect them from the active output jack of the top amp to the passive of the bottom amp. So I ordered the parts to make the cable from Small Bear Electronics. Here's what I ordered: http://www.smallbearelec.com/servlet/Detail?no=131
A 1/4 in. Mono, Flat, Right-Angle jack. Stacking one amp on top of the other doesn't give me much room for a standard sized jack, so I figured a small, flat jack would work better. I got two of these. I also got 4 ft. of this: http://www.smallbearelec.com/servlet/Detail?no=998
Proco 120SX instrument cabling. Standard instrument cabling.
So this afternoon I soldered everything up, then I plugged it in to the active side of my GK combo, and plugged in the other end into my Yorkville combo. I was disappointed to find out that while the signal was getting through I had to crank up the Yorkville to the max to get any sound out of it. Yet when I plugged in a regular instrument cable the Yorkie was nice and loud.
Is there something about those small flat jacks I'm not aware of? Why is the regular instrument cable so much louder?
