Firstly when you step on it it makes a large pop sound, a 1m resistor could sort that EHX and it only costs a fraction of a cent, secondly the features, the switch is pointless, one way its barely audible the other way its active, when it was active there was an intermittent static noise and it is not a very deep chorus effect. So after installing the 1m pop resistor, repurposing he switch to change cap sizes for deeper modulation (it sounded not much like the Nevermind album until modded) and replacing the 3007 and 4047 chips along with a couple of other resistors it now works as it was intended. This will be the last time I buy a product from EHX.
