I'm a plug in the amp kind of guy but I have this cheap Sovtek Tube Midget 50 watts that sounds good somewhat cranked, I don't have the ability to open it up at home to see what it would sound like really cranked. I'm looking for high gain non clean grungey low down meanacing sound...think Boris...Melvins.... What do I need? OD or distortion pedal? How about fuzz? Thanks in for helping me pop my pedal cherry.
