I just picked up two used Earthquaker Devices pedals in the last week or so, and like them so much that I've got a third one on the way. I got an Arrows boost and a Speaker Cranker, and they're both going to be used a lot both for recording and in a live setting. I think the Arrows is the boost I've been looking for. It's not entirely transparent, because it's designed to give your tone a midrange bump to cut through a band mix. It does exactly that! The Speaker Cranker is great on its own as a semi-clean boost, but when turned up it really drives a clean tube amp into overdrive nicely. And it gooses other dirt pedals really well, too. The pedal on the way is an Erupter Fuzz (one knob!), so I can't wait to see how that works out.
