Did a solo bit at church this morning. My Fishman loudbox mini was working fine when I practiced last night. Got it to church and set up, turned it on and got what sounded like fuzzy radio air. Weird....plugged in and turned the amp back on to howling feedback...got the master volume down in a hurry. There's a constant hum with volume down, gingerly turn the volume up a little and I'm getting massive overdrive tones. Bleh...plan two using a DI box to the PA. I like having the Fishman as a stage monitor but this would have to do. When I got home I tried the amp again with the same results. I figure something in the preamp stage is gone with the amount of volume and distorted overdrive I'm getting. It's unusable as an acoustic amp. The mic channel seems to respond OK, besides the constant hum from the instrument channel. Even when I turn the instrument volume all the way down there's a hum. Ripped it apart and looked things over. There's nothing obvious...no burnt/charred components. All the solder points seem firm. I was really hoping something wiggled loose on the car ride but I'm not finding it. I considered looking into sending it somewhere for repair but in my experience solid state issues usually mean replacing the entire circuit board which equates to expensive. I've had and used this amp for a 6 years now so maybe this is an opportunity to upgrade. It would be nice to have something with separate DI outputs for each channel so I'm considering a Fishman Artist. I'm looking for feedback or suggestions on a new Acoustic amp. Must have 2 channels, be under $1000 Canadian (about 790 US), prefer separate DI out for each channel (to keep the sound guy happy). Have enough oomph for small/mid solo gig when a PA isn't around. I like the Fishman Artist on paper but just wondering if there's anything I should look at.
