Question about Roland Boss ST-2 Power Stack Distortion Guitar Effects Pedal

1 Answer

A musician friend of mine asked me to take a look at his pedal. Apparently there are issues with it cutting out. I figure it's just a bad lead connection on either the input or output jack, but can't really say for certain without a correct wiring diagram. Is there some sort of diagram available for this pedal?

Diagram is NOT likely to help much. Look for bad soldering at the input and output jacks AND by the power input jacks. Also look for cracked circuit board and or lifted circuit etch. Lastly, the pots and the soldering around them may be part of the problem. Most of the mentioned things are 95% of the problem.

You are either trying to: (A) push it too hard, (B) using the wrong type of fuse -- should be a "Slo-Blo" type, or (C) it has internal shorting or voltage modulation and requires service.

Marshall MG50DFX is cutting in and out


Often the bypass contacts on the FX insert jack fail to close. These jacks are really poor and after plugging in a plug several times the bypass switch contact becomes sprung so as to not make good contact causing symptoms like yours.

Open the unit and inspect the jack. You can bend the contacts to tighten them BUT they will fail again.

Externally sometimes you can make a short jumper cable to connect the preamp out to the PA in to bypass the failing contacts.

On an insert jack, you can just wire a TRS plug tip to ring and plug it in.

My Line 6 Spider Amp sound goes out when I plug in my FBV express pedal. Any advice?


Read this cut and paste and verify compatibility as a first step:

<<<
*FBV is not compatible with Spider II 15 or Spider III 15.

**FBV is only compatible with POD 2.0 units with pedal jacks labelled "FBV Pedal." It is not compatible with older units which have pedal jacks labelled simply "Pedal."

(NOTE: FBV is NOT compatible with Ax212, Flextone I, II or HD, POD® Pro, Bass POD®, Bass POD® Pro and Spider.)
>>>


Note there are apparently several versions. Check compatibility at this site:

Hi i have a 9150 rack system and an 8050 foot controller. i am having problems with either the lead or lead sockets,they cut out on odd occasions,i cannot locate a new lead anywhere


Apparently you can use a standard midi cable but will have to use the external power supply for the 8050. Try cleaning the contacts on the jacks and make sure you are using matching midi channels on the rack and the 8050.

Sustain pedal not working on my Yamaha P-90


What I figured out is that when i turn on the keyboard, if i hold down the pedal by accident, it will work in reverse. I dont know if this is what you mean. If it is, just dont touch the pedal when you turn it on. If it isn't, try to return the pedal. I dropped one, it had this problem, and they gave me a new one. Your cord for it might have been bent (?). Also, turn the keyboard on with the pedal already plugged in. It's not made to be plugged in while it's on. Hope this helps. - Matthew

Casio 1600 sustain pedal problem


Not if its like mine, its a completecircuit vs.incomplete circuit problems.

I had the exact same problem with my Casio keyboard and a Yamaha sustain pedal I bought.

I'm not an electrical genius, but I was able to get it to work by opening it up and doing a little modification. Of course I first just tried switching the white wire with the black one but that didn't change anything at all when I tried it. It turns out the Casio wants the circuit completed to sustain, and broken for no sustain, which is the opposite of what the Yamaha pedal does.

I opened it up and mine had three three flat metal strips let's call them Top, Middle and Bottom. The Middle and Bottom ones were joined together on the right side, and the Middle and Top ones were touching on the left side when the pedal was not pressed. These seperated when the pedal was pressed, thereby breaking the circuit because the wires were on the top plate and on the joined Middle/Bottom plate.

So to flip it I:
1. Unsoldered the Bottom wire
2. Cut apart the Bottom and Middle plates on the right.
3. Bent the Middle plate on the right to touch the Top plate instead and soldered those together.
4. Soldered the Bottom wire back on.

That's it! Once I figured it out, it took only a few minutes to fix.
Good luck!
