Dude. It's a good time to be a bassist looking for dirt. There are a ton of great dirt boxes out there for us nowadays. I'll name some I use and or know about that work for me or sound great to my ear.
DOD Carcosa- great versatile OD to fuzz. Affordable too. One of my favs
Way Huge Russian Pickle- Great green muff
Big Game Bedlam- OCD style drive/dist.
Way Huge Pork loin- I have a modded one and it's become one of my fav all time ODs
Idiotbox Blower Box- Rat style OD to heavy dist. Its a really sweet, mean and unique rat drive. Love that pedal
Fuzzrocious Rat/Cat Tail- It's a bass rat. It rips it tears it pillages. Its rules.
I havent had much success with it, but many others here have, the team awesome fuzz machine (TAFM) by small sound big sound (SS/BS). Its pretty versatile.
Of course there is the Darkglass stuff, the B3/7K or the Vintage series. All are awesome and great, but not for everyone. Plenty of YouTube demos out there for you to check out to see if they are for you.
I havent played one but I am hearing a ton of great stuff about Damnation Audios MBD1- versatile, monster of a bass dirt. And Electrical Audio is making some killer products as well.
It all depends on what you're after
@Wrylygrin85. I hear good things about the Aftershock too if that's something that sparks your interest. Seems hard to go wrong. But def do your demo shopping, there is so much great stuff out there right now be it fuzz, dist or OD or all of them! I named a lot of what I feel is among the stuff that actually worked for me in a band mix. My band mix anyway
And almost all those companies are wonderful to work with. Good dudes/people building good/great pedals.
And what type of band are you in??
