I found a pedal manufacturer I really like and would like to share with the group - http://www.lounsberrypedals.com. For the record - I have no connection with Lounsberry Pedals (except as a satisfied customer), I don't make a dime off of their pedals and I don't ask for or get discounts. I have four of their pedals and paid full price for each one. I'll also pay full price for a couple of pedals I'm planning on getting in the near future. I saw an advertisement for the Lounsberry Organ Grinder and it sounded like an interesting pedal so I bought it. It adds a warmth and richness to your sound with no loss of low end so you can keep it on all the time. It also adds some grind when you play double stops or dig in a little bit (or a lot). I didn't have a specific need I was trying to fulfill when I bought the pedal, but when I used it with my 6 string SX, it really brought the sound to life. The thing I really like about the pedal is that, unlike a built in preamp, I can use it with any of my basses. I have the 6 string SX which I really just tinker with, but i have a 4 string I use live for drop tuning. I won't say that the pedal brings the SX all the way up to my MusicMan soundwise, but it makes the SX sound very good. Also, I called Greg to talk to him about a pedal with a little more grind and he built me a pedal that is somewhere between the Organ Grinder and one of his overdrive pedals, the Nigel. This custom pedal sounds like the Organ Grinder when bypassed, but has a lot more drive like the Nigel when it's on. There are a lot of subtle and not so subtle sounds in this pedal and I was able to get a really good Larry Graham "Dance to the Music" grind going on. Anyway, I recommend that you look into these pedals. Greg is a good guy, easy to work with and he now has a pedal designed specifically for the bass which I'll add a review for as soon as I get it.
