This product is good for anyone that wants a tube distortion with an added filter. Very tweakable. Kinda bulky space-wise yet rugged construction-wise), but it's justifiably so b/c of the tubes. When I turn it off it is dead quiet. Make sure you don't trip on the adaptor cord b/c I find it'd very easy to slip out years later after heavy usage, and also it's a unique adaptor type. I'd recommend this to anyone looking for out-there effects or anyone in need of tube distortion. You can turn the resonance knob all the way down and the filter is bypassed. The frequency light continues to work when the pedal is turned off, allowing you to see how it will modulate your signal. I also find that you need the master level a bit lower than you think and raise your amp's level instead b/c you get used to the fat sound. Turning off the effect: your clean signal is super loud so turn the master level on the pedal down. This product is fun to use with a drum machine and delay. Overall, it's a good effect but is pricy b/c of the construction and two tubes.

This pedal has so much to offer. This is for anybody into experimental style playing. I have found myself tweaking, looked up and 3 hours had gone by. Quality is excellent, value is a little pricy, but the features of this pedal are greater than any other analog pedal out there. The passthrough is excellent, no noise at all. Get this pedal if you are looking to create your own unique sound.

This pedal is absolutely amazing! I've been wanting to buy this pedal for two years now but had to settle for the Mini Q-Tron due to lack of money. But I finally got it and all i can say is "wow"! It's everything I thought it would be and more! Electro-Harmoinx simply makes the best effects pedals in my opinion, and this is no exception. The Tube Zipper might be confusing for some if you don't know how to work it, but just stick with it and mess around with the dials and find what you're looking for. Now go get that John Frusciante funkified sound!

This thing is off-the-wall insane!! This is the first pedal I bought about two years ago and I'm still figuring out new sounds to this day!! If you want something crazy and cool get this pedal...also makes a pretty good overdrive if you can stop making crazy noises.

I recieved the Tube Zipper for Christmas expecting an English Muff'n. I was pleasantly suprised! First of all, it came in a cool box. We're off to a good start. When I opened this wonderful box I found a piece of paper with some sample settings. Great! I watched the demo on this site and the thing looked complicated, but after fooling around with it you'll get the hang of it.

One of my favorite aspects of this effect is the size. Its' BIG! (Compared to my only other effect pedal) It's an impressive sight. It also has a cool grill covering up the tubes.

I put a 7 for value because that's average and...I did't buy it.
