Re: Boss BD-2 vs. MI Blues Pro vs. OCD
Need a little more info about exactly what you want!!!!! There are a ton of pedals and we each will recommend something different...
Is this for: Total pedal OD, or pushing the amp?
What does medium gain mean to you? Tube screamer style, or Metal Zone?
What guitar? Single/Buckers?
When in doubt on this issue, I'm going to off the cuff say that the TS-9, Boss SD-1, and Bad Monkey are all fantastic classics. No reason to go crazy with a basic OD.
I am not a fan of the BD-2 for no particular reason, am not familiar with the Blues Pro. OCD is much loved. Of those three, I'd pick that.
