| Yes, that's quite likely, although you should check all the batteries and power supplies to make sure they're ok. That includes the battery in your bass!
I solved a similar problem by using the level matching features of the EBS MicroBass II. But there are cheaper and simpler ways of doing the same thing - a simple attenuator box can be made with a couple of jacks and a pot, but it's far from ideal. Basically, any device that can handle the hot input without distorting, and has an output level control can be used to tame the hot signal. Just put it up front in the chain and drop the level until it cleans up.
Naturally, the quick fix alternative is just to turn down your bass!
