MT-2 it is C41 and it is 100uF 16VDC.
DS-1 it is C21 and it is 100uF 16VDC.
The only input capacitor I've ever seen that needed replacement is one that had been overheated when the reverse protection diode failed in a PW-2. If you could explain the symptoms you are seeing, maybe we could help diagnose the problem?

this morning when i plug it it sounded so slow the volume will increase and its not normal sound, as i stum my guitar harder, then after a few minutes it will be in its normal sound then when i turn it off again it will come back again, i bought a 1000ma adapter coz i think it was the problem but i was wrong, a friend of mine told me that maybe its in the input capacitor but i dunno where is the input caps hehehe
one more thing, my adapter can switch to 6 volts, so i switch it there then it sounded ok there but the light was not bright and the gain decrease |

Ah... the caps I gave you are the power supply input caps, not the signal input caps.
It is unlikely that two pedals have failed with the same fault at the same time (but not impossible!)
I'd suggest looking for other causes... Are they both powered by the same power supply? Have you tried them with a known good battery? |

Also, have you tried it with another guitar cord?
Or even another guitar?
Have you plugged straight into your guitar amp, bypassing all pedals completely to make sure it's not your amp or guitar?
Assuming you use a small patch cord between both pedals, have you tried a different one? Especially cheap patch cords are known for weird volume drops/swells, try wiggling around with the jacks.
Good luck. |

hi Laurie, doc Bob,and Dirk
so do you know where is the input signal caps located? its not in my guitar chord not not in my guitar or amp its my problem since last year, especially during cold weather, what i do is to put it at he back of the fridge coz its warmer there, then when i use it it will be ok |

Hi macOy!
The main thing I have seen that responds to hot and cold like that is a "dry joint"... where the solder isn't properly making contact and the heat expands the metal and makes the contact.
If it is a dry joint, they can be really hard to find. I think at this point some high resolution/really clear pics of the solder side of the circuit board would be a good thing for us to see.
