I’ve been playing with my new 22 cal for a couple of weeks now but today, when I was showing it off and playing loud (about 60% on the dial) it started cutting off. It would drop to silent and then come back on, drop and come back on until the volume dropped to a certain level and then it’d come back on full time. Drive it hard again and it’d do the same thing.
I plugged it into a variac w/ an ammeter on it just to see what was what and noticed that anytime the power draw got much above .6A (six tenths of an amp) the sound would cut out.
Other than that I love the pedal and would sure like to continue using it. Is mine defective? What will it take to get it fixed?
Help??

From what you are describing it sounds like the cabinet you are using is a 4 ohm cabinet.
When we first sold the 22 Caliber we said it could work down to 4 ohms but we were wrong. When plugged into a 4 ohm cabinet, as soon as the 22 Caliber starts to distort, it overheats and shuts itself off. This usually occurs at around 11 o’clock on the dial.
The minimum cabinet impedance should be 8 ohms. If you are using an 8 or 16 ohm cabinet then something may be wrong with your 22 Caliber.

http://www.campbellsound.com/Definitely interested to hear your results with the 8 ohm cabinet. It should be fine.

It’s doing well. As soon as I plugged it back into the 2×12 4ohm cab the amperage went up, so I stopped and concluded the “test”
