It's almost like running a cheap compressor and having an EQ in the loop with the bass emphasized and the treble almost shut off. After a few weeks of trying everything I quit using it. I can really enjoy using. Maybe if you play with heavy distortion you'll have better luck. Then just rock the foot.
Any idiot can work it.
I run a Epiphone LP through a Mesa Dual rectifier. I ever bought. I'm just glad I bought it before I really knew what I was doing, or I'd really be embarrassed for getting. I bought an original crybaby recently. It quit working after a year of very occasional use.
