ive got this guitar effects pedal and it needs repaired .... their are 4 foot switches that need replaced and a digital swich. the 4 foot swiches are circled in red and the digital knob swich is broken off and circled in green where it used to be, and also close up pics are below. the digital swich/ knob operates the small digital screen on the board and can be spun in both directions infinitly as the numbers go up into the hundreds. there is no start or stop to this knob. if someone could identify these parts and tell me where i can purchase them to swap them out on the board it would be a great help !!
cant get the pics to work y ? |

First, good job in posting the pictures..
The broken control is obviously a potentiometer, however the numbers do not indicate the value & short of attempting to measure & guess the value, the sure way is to get a schematic that won't be easy. Not sure on the 4 footswitches, they appear to be simple push switches called "tact" switches and there is nothing special about it. Same type of tact switch is used on just about any thing electronic that has a push type button. Unless they are physically damaged & don't have the springy action, there is no need to replace..
I have seen several DODFX7 posted for sale on the net for around $30-60 & may not be worth the trouble.
.....btw, have a DIGITECH GNX4 processor & it's awesome. |

In closer examination, the broken control is NOT a potentiometer; it is actually an Encoder & CTS actually has a "288" series of encoders available. (forget measuring it). It is even more critical to use one with exact parameters or will not work.
Digikey has a selection, but w/out knowing the exact parameters, it is a hit or miss
