    I posted this in the stompbox forum but got no response, so I thought I would ask over here...

    Mods -- I hope this is ok, and if the first thread needs to be deleted, please go ahead :)

    I recently picked up a vintage Drive Master pedal off CL.

    It makes a lot of noise. Even with the volume and gain rolled way back, there is significant hiss, and if I crank it up, the hissing is ridiculous.

    Would anyone know if this is normal for this pedal? I opened it up to have a look at the board and didn't see anything obviously wrong. I did notice, however, that when the pedal is switched on, the clipping LEDs do not light up. Again, I'm not sure if this is a normal thing or not. Also, there is one electrolytic cap on the board at C7 and I was wondering if this might need to be changed due to its age.

    I should also mention that it passes signal just fine, and there doesn't seem to be anything wrong with the general sound of the OD. The tone controls work just fine, except that they will enhance the range of the hiss in the frequency band that they cover.

    Thanks for your insights :)

    Hi there

    An old user here

    And still using it. I use with a Bassman LTD and a TS808 before ALWAYS ON. Just for leads and that stuff.

    1-NO hiss at all
    2-No, LEDs don't have to light up to work as a diode
    3-No need to change anything in mine. Well had to change the stomp switch years ago. At that moment I realised LED didn't light up but the pedal worked

    4-No problem ever but have to clean pots from time to time (two times in 15 years I believe )

    I use plain Boss type power supply with a daysy chain and no problem ever

    Sorry I can't help much more

    I had not thought of the power supply, so thanks for the suggestion. I will try with a battery instead!

    Actually, that's a huge help. Without knowing what the noise floor of the pedal is supposed to be, it would not be possible to know if mine is malfunctioning. So thanks for letting me know how yours performs :)

    You might PM @11Gauge and ask him about it.
    I've read a good bit of info he posted about the Drive Master and similar Guv'nor.

    OK, so I tried a battery instead of the Boss power adapter, and the hiss did not change. Excellent thought though...

    I would love it if he'd stop by and share his thoughts, but I don't want to impose with a PM.

    I also read some of his posts about the Drive Master, but most of it was over my head!

    He also AFAIK does pedal repairs along with new builds.
    My Drive Master isn't as hissy as you describe so it seems you could reasonably ask him about fixing it.
    I have a pedal or ten I could send his way when i free up some cash flow...
