I'm getting a crate V50 which I know doesn't have a very good distortion channel. I'm getting a distortion pedal to fix this but I don't know which would be good for this use. I play grunge, punk, metal, rock, and other genres like those. I've looked at the French Toast octave distortion pedal by Danelectro and the Bad Monkey tube screamer and I like them both as pedals. But I don't know if they would be good for how I'm using them. Are either of these two good or is there something better for a reasonable price. Thanks much!
