Well, I bought a 1001RB-II on Ebay. Took it to band practice tonight. In my haste/excitement/stupidity, I connected the GK speakon to my Eden WT-330 speakon instead of disconnecting the speakon from the Eden and connecting the cab to the GK. That's right... I disconnected the speaker cable from the speaker instead of the Eden and connected amp to amp. The Eden was turned OFF. I powered up the GK. When the light turned from red to blue, there was a medium volume pop which I did not expect. On the GK, all EQ knobs centered, all other knobs at zero, -14db input pad engaged. Turned the volume up about 1/3 on my active bass, preamp up about 40%, master up slowly. Very distorted, even at low volume. Tried different settings on preamp and master. No good, still very distorted. So, I gotta ask... did I blow this amp putting its speaker signal into another unpowered amp? Could the 1001 have blown that fast if the impedance it was connected to was very low? The GK is definitely blown, I just want to know if I did it. The seller's add said that everything worked as it should, no issues. If you can type and laugh (or cry) at the same time, I would appreciate hearing from the TB community. Thanks.
