Hey guys, I have hauled this amp to my amp tech twice and spent $200 but have had no luck. I have a 2005 Ampeg SVT CL that is doing the power fault led flash when using my Mark Hoppus bass through it while driving the amp hard. This ONLY happens when driving the amp hard with that specific bass (around gain 4, master 7). The amp makes a poof sound and fades away then the power led starts flashing. If I use my Ibanez bass everything works just fine. My amp tech has resaugthered the board and biased the amp. I think the Mark Hoppus bass is driving the amp too hard with the Seymour Duncan Quarter Pound pickups. Any experts know what might be going on? Is it just a situation where I can roll the bias back a little bit on the back of the amp? I've had this amp for a few months and really want to enjoy it, it's been in the shop for 3/4 of the time.
