I just acquired 1 of these. $125. Literature says it’s a purpose design for steel guitar and 200watts. Solid state with a 15" Black Widow.
I bought it from a non-musician who knew nothing about it and I test drove it outside on his front porch with my trusty SM58. I thought it might have potential, his 20 month old daughter thought it was the coolest thing she had ever seen or heard (I’m sure she would have been dancing if she knew how to walk a little better) and they looked like they could use the rent money so I bought it. I don’t have buyer’s remorse, but I do have feedback.
An authoritative drunken harmonica player once told me that the only time you have to worry about feedback is when you stop playing, but I am hoping to find a more practical solution. After a little more experimentation and maybe knowledge, I will write Peavey and see if they can recommend a fix. Their tech support is legendary, they may already have a fix.
Any suggestions y’all might care to offer are appreciated.
