Well, I bought a Behringer GM108 practice amp on April 15th. Last week, it started making a thud and static when playing. I have a replacement coming from Amazon tomorrow. Only problem is, I'm not too confident in the brand after this, even though their wah wah pedal seems to hold up. My question is, what's a good solid state practice amp. I kind of like the Fender Frontman 10G or the Marshall MGCD10 (I think that's the model). Anyone out there with any experience on these 2 amps? I'm not limited to just those 2, so feel free to share what else you can. Whatever I get has to have a headphone jack and mp3 input. Thanks for any info!
