Hey Coopertron
I have owned both
pedals.
I would say the first difference is price. The BH is cheaper than the BH2. If you go on a popular auction site, you can get either one for a real nice price.
The BH and BH2 both have switchless engage. As soon as you step on it, it's on. Which is one reason I love these pedals! I love the
wah sound out of both, too.
The main difference is that the BH2 has a switch on the left-hand side. When you switch it on (a red LED will show that it is on) you can use the "contour" knob to adjust the tone of the wah. It can get pretty extreme! The other knob is "volume". I LOVE this! It gives you quite a boost of volume. I enjoy these added features.
I would say that both pedals sound pretty close to the same...if you have the BH2 switched "off".
If you turn the BH2 "on" it just opens up more possibilities.
I play Ibanez Jem guitars through a Marshall DSL100 and Marshall cab. I have been using these wah wah pedals for about 8 years!
I started with a BH and after using it for a few years I bought a BH2 so that I could try it to see which one i preferred. Well....I decided on the BH2. I still use it...it is my only wah. I have been using it now for about 4 years and I love it. I gave the BH to the other guitar player in my band at that time and he still uses it. He told me that he will never get rid of it! In fact, I know of 4 guitarists who went out and bought a BH2 after they heard/saw mine at a show! I think it's because of it's ease of use and probably even the fact that you can make adjustments to it's overall sound.
Anyway...I am rambling now...I hope this helps you a little bit in your decision. I would say that you can't go wrong with either wah.
good luck
