Description:
EHX has resurrected the legendary Bad Stone Phase Shifter. With prices of 1970s’ vintage Bad Stones soaring, now is your chance to get a reissue that is faithful to the original circuit design and three-knob control layout, but features up-to-date enhancements for the modern player.
The Bad Stone delivers an incredible six stages of phase shifting plus a manual mode that lets the player freeze the phase. Its Rate knob controls the phase shifting speed which goes from a very slow swoosh to a rapid, oscillating warble. Feedback determines the depth of the phase effect and a toggle switch lets the user select Auto or Manual modes.
In addition to the die-cast package, other modern amenities include true bypass for maximum signal path integrity, an effect status LED and an AC jack that accepts an EHX9.6DC power supply.

Perfect on 1999 Volvo v90 XC AWD
I had looked everywhere for an oil filter wrench that would fit the cartridge filter on this1999 Volvo v90 XC AWD. Nothing local worked and then there was the issue where the recommended filter wrench slipped.
When I was ordering the 86.6mm wrench, I looked at the pictures and noticed it said if I had a specific type of marking on the housing then I would need this 86.4mm wrench instead.
Thanks to that bit of info I can now replace the filter.
Works 100% like a charm and filter was easy to remove with a standard ratchet.
Wrench seems well made and the price was perfect, especially compared to some of the others that are $35+.
Very satisfied with this purchase.

Money Saver!!!!
Purchased yesterday and put bot cans in my gas tank. Very pleased with how it works. Had a code P0175 02 sensor bank 2. Thought I had to replace the sensors but looked into products and read the reviews of these can. Check engine light went off this morning. Drove it aggressively after I used the cans and they worked as advertised. Highly recommend.

car performance improvement
I bought this to use in my 2021 chevrolet equinox when my check engine light came on with an exhaust issue. so far I believe it's working. I have noticed increased mileage and a little more "zip" in the engine.
