It wouldn't be too hard to design and make. All you would need is a heavy duty momentary single pull stomp switch, a small PC board, a 4017 chip (about 1 dollar) some jacks and 1 or 2 4018 chips (1 allows use four things to plug your expression pedal into, 2 allows you 8 things)the 4017 is a decade counter. It has 10 outs, and you decide the ammount of steps by connecting the last step to the reset pin. You wire 8 of the 4017's pins to the 2 4016s ins.4016s have 4 different switches and 4 ins. When you give an in power, it closes a switch and makes a connection (which would be the connection between your expression pedal and the expression in of one of your pedals)You connect one side of the momentary switch to ground, and one side to the 4017 clock in. When you close the stomp switch, it connects the 4017 clock in to ground and makes one step. The step gives power to a certain 4016 switch, and closes one of the 4016's switches connections.So in essence, you can use 1 stomp to control 8 switches. The only downfall is that you can't skip steps, so you have to stomp through several before you can get to the one you want. The simple option is to make a box with an expression in, and as many expression outs as you want, and use a rotary switch to choose which pedal you want to send it to. The downside is that it is not a simple stomp, you gotta tweak it with your foot or bend over. The upside is no PCB, and it is a slightly simpler project.

Members SpectralJulian Posted April 18, 2006 Members Share Posted April 18, 2006 Just remember- PEDAL INPUTS: All pedal control input jacks are 1/4" tip-ring-sleeve (stereo) phone jacks. The sleeves are grounded and the ring terminals are supplied with +5.7 volts which is current-limited to about 0.5 milliamperes. The tip terminals receive the variable voltages from the pedals. An expression pedal for use with the MF-103 should contain a 50KW or 100KW potentiometer which is connected from the sleeve to the ring terminals. The potentiometer wiper is connected to the tip terminal. The pedal cable should be shielded, with the shield connected to the sleeve terminal. See Figure 11. When connecting one or more pedal control input jacks to a source of external control voltage such as an analog synth or a MIDI-to-CV converter, you should use patch cords with tip-ring-sleeve phone plugs. The ring terminal on the plug should not be connected to anything, so that the MF-103's source of +5.7 volts is not shorted out. Or, if you do not plan to use any expression pedals with your MF-103 but would like to apply control voltages to one or more pedal control inputs, you can use patch cords with regular two-conductor phone plugs. These will short out the +5.7 volt supply to the ring contacts. This voltage is current-limited, so you won't burn anything out, - but no pedal will work in any of the pedal control jacks if a tip-sleeve plug is plugged into even one of the pedal jacks. Applying a varying voltage to the tip terminal of a pedal control input jack has the same effect as turning the corresponding knob. A voltage change of about 5 volts at the tip terminal is equivalent to turning the corresponding knob through its entire range. You can 'program' your MF-103 performance parameters entirely from external control voltages, by turning all four control knobs (but not the DRIVE or OUTPUT LEVEL knobs) counterclockwise, and feeding 0 to +5Volt programming voltages to the tips of the four pedal control input jacks.

Without a website, all the reviews help! (ofcourse, not the negative ones. )@Olle, do you prefer the low-gain or high-gain mode? Link to comment Share on other sites More sharing options...

Yeah, but I can only think about making pedals because I don't have any capital to make them. Check back in a year. Link to comment Share on other sites More sharing options...
Members DonaldDemon Posted April 19, 2006 Members Share Posted April 19, 2006 Thanks for the idea! This may solve my pedalboard problem finally. I have a few more things I want to add but they won't fit. I will get a smaller board for the loop which will be chorus->trem->analog delay-> digital delay. Anybody use this as a live set up? I'd really hate to add to my set-up time but it may be the best way to go. Link to comment Share on other sites More sharing options...
