Bought this used, sounds great until signal decay/ Basically, what happens is after the first (heavy or clean) attack is good, but as soon as the decay begins, it seems to fall of IMMEDIATELY to zero, rather than "Cruising down."

I used the headphone jack so I could test to see if it was speaker -- same issue. Any ideas/suggestions, folks?

PS: If there is a more specific area I could have posted this, feel free to let me know and I will move it to its rightful area...
