    i have a fairly simple setup now that im in an original hard rock band...wah>OCD clone>MXR micro amp>tc electronics tuner...
    i switched out the OCD for the BBE, and as soon as you turn it on, the volume drops easy 50%...maxing the volume doesn't even bring a unity level
    would the micro amp or tuner have an impedance level that's crushing the BBE?

    Run some deoxit in and out of the jacks of the BBE first. If you want to check impedance, try it at both ends of your chain and see if there's a difference.

    Highly unlikely there would be any impedance issues in a new issue. More likely that something has gone amiss with the stompswitch. This picture someone posted suggests it is the same stompswitch type I normally order and use. These can occasionally fail but be easily restored to working condition, as demonstrated in the video I posted some time ago.

    Cool...i tried taking the wah out before it, but didnt change anything
    I didn't realize a switch could fail while still passing signal...i can take it apart...i may even have an extra one kickin around
    Thx guys

    They CAN be rehabilitated. You do need to be careful prying up the tabs to get inside - they can only take so much bending before they snap - but I've restored many that became "involuntarily insulated". It happens. The dab of grease does serve a purpose, but the switch will continue to work without the grease, if you need to clean it off.

    I made the video because the failure rate being reported by hobbyists was WELL in excess of what would allow the manufacturer of such switches to stay in business, if their major commercial clients were experiencing a similar failure rate. The problem seemed to be that hobbyists were soldering to the switch lugs in a manner that exceeded the switch's ability to manage heat, and was liquifying the grease. Manufacturers get in large batches of switches with gleaming untarnished contacts, and use well-planned soldering methods that get in and out quickly, drastically reducing (though not always eliminating) the risk of liquifying the grease.

    If you do attempt disassembly and cleaning, make sure you don't lose any parts.
