avt 275 "cricket noise?"

big e · 09-06-2009, 08:16 AM

had not played anything on avt 275 for about four years. always kept in climate controlled conditions. just bought a ltd viper-400. started playing and didnt noticed anything. after an hour or so started noticing a "cricket" sound. more pronounced on clean. no cricket unplugged and turned on. took guitar back to store and plugged into different amp, no noise. noise increases with volume.

It sounds like it might be a bad or microphonic preamp tube. Try swapping your preamp tubes with a known good tube one at a time. If you don't have a spare, try switching them around to different positions.
