I want to run both an effected signal and a clean signal from my bass to my amp. I got a Dunlop Bass Wah 105Q. It doesn't have a on/off switch. I got an A/B box which allows either or both to be on. I ran one cable from my bass (passive pick-ups) to the Input of the switching box. One cable from output A to Input of wah. One cable from output B to a Y connector. One cable from output of wah to the Y connector and Y connector to amp. I understand that I am splitting the signal and expected the output to be diminished. When I have the clean signal selected, the volume is low. When I have the Wah channel selected, it works but is also low. I expected this. When both outputs are on, the clipping diode on my amp lights up and the amp makes an airhorn-like sound. My instincts tell me that isn't good for the amp. My amp is a G-K 1001RB, if that makes a difference. This doesn't make sense to me. What am I missing? It is not like I am running a short to ground. If anything, I'd think the 105Q would be bypassed as the signal takes the lesser of the two loads. Could the box be miswired? Am I supposed to run the effected signal and the clean signal to separate amps? Should I try this again with a basic effect pedal to eliminate the 105Q as part of the problem?
